2005 Bremerton Water System Plan
Introduction
The City of Bremerton has a remarkable resource: a clean, abundant water
supply. Surface water from the Union River and groundwater from production
wells provide the source for Bremerton's water. The City supplies
approximately 3 billion gallons of water each year from these sources to over
56,000 people, representing over a third of all drinking water supplied in
Kitsap County.
Bremerton's water system is a Group A System operated as a municipally-
owned water utility under the direction of the City of Bremerton Department of
Public Works and. Utilities. Bremerton Municipal Code regulates City Utility
operations to provide safe and reliable water service. The water service area
consists of the Bremerton City limits and portions of the surrounding
unincorporated area in Kitsap County. Approximately half of the water is used
within the city limits, a third is provided to the Puget Sound Naval Shipyard,
and the remainder is used in the unincorporated
areas. All customers are represented by the
Bremerton City Council, the Bremerton Water
Utility's governing body.
Purpose of the Update
The 2005 City of Bremerton Water System Plan
(WSP) Update was prepared in response to
Washington State Department of Health (DOH)
regulations, which require all water purveyors
to update their water system plans every 6
years. Changes since the last plan that affect
Bremerton's water system planning include:
. Projected population growth increase in Bremerton's water service area,
with a resulting projected increase in potable water demand,
. The update ofthe Kitsap County Coordinated Water System Plan, in which
Bremerton's water system figures as a key element,
. Passage of theW ashiIlgton State Municipal Water Law requiring water
systems to implement more specific water efficiency measures and requires
more coordiIlationofwaterplanning between state and local agencies,
. Assumption of the Tracyton Water System by Bremerton in 2004, and
. Implementation of Watershed Planning for the Kitsap Peninsula in 2000
and plan veto in 2005 which halted the process.
Executive Summary
2005 Bremerton Water System Plan
The Water System Plan Update describes
. The existing water system,
. Future demands on the system forecasted over a 20-year planning horizon,
. A conservation plan designed to lessen these predicted demands, and
. A number of potential capital improvement projects to address supply,
distribution, and storage needs in Bremerton's water service area.
In accordance with the Growth Management Act, this plan is designed to be
consistent with other City of Bremerton, Kitsap County, and regional plans for
land use and municipal facilities. It will be used by City planners in their
review of proposed land use actions to ensure that these actions are compatible
with the long-range plans for Bremerton's water system.
Forecasting the Growth of Water Demand
The key to developing a water system planis the ability to project the demands
that will be made on the system in future years. In Bremerton, planning for the
water system's future must take place on both a local and regional level.
City of Bremerton
Water Demand Forecast
Population growth and the
resulting water demand
were projected for the
entire Bremerton water
service area on the basis of
Comprehensive Plans for
City of Bremerton and

Executive Summary
2005 Bremerton Water System Plan
Meeting Future Needs: Planning for Conservation and Water
Supply Strategies
Water conservation is an important means of deferring
the need to develop additional sources of water supply.
Conservation can serve as an additional increment of
supply by enabling the existing transmission and
distribution systems to serve more customers while
maintaining the same capacity. The ability to postpone
the construction of capital facilities makes conservation
an option that is both cost-effective and environmentally
sound. The conservation plan combines proven
measures used by the Bremerton Water Utility in past
years with public education and involvement activities
promoting the advantages of water conservation by
means of school programs, special events, and the
distribution of home conservation kits, printed information, and mass media.
Overall, the recommended conservation measures are projected to result in
water savings of 5.2% by 2024.
Potential regional water supply opportunities to meet predicted growth m
demand include:
. Maximizing conservation opportunities,
. Expanding groundwater resources,
. U sing reclaimed water from the City's wastewater treatment plant, and
. Aquifer storage and recovery.
Recommended Capital Improvements and Financing Plan
The Water System Plan contains the City's capital
improvement program (CIP), developed to guide the
growth of Bremerton's water system through the year
2025. Included in the CIP are:
. Improvements to distribution system plpmg and
storage,
. Construction of an ultraviolet treatment facility to
meet new federal regulations,
. Upgrades to groundwater supply systems, and
. Continuation of seismic and security upgrades to
supply.facilities and reservoirs.
The total cost of capital improvements proposed from 2006 through 2025 is
$48 million. Funding will come from a variety of sources, including developer

extensions, capital facility charges for new hookups, state and federal loan
programs, rates, and bond sales.
The capital improvement program developed in this plan is highly dependent
on the rate, location, and nature of future development within the Bremerton
Service Area. If development proceeds in a manner significantly different
from the assumptions and projections used for this plan, revisions to the CIP
may be necessary.
Looking Toward the Future
The main challenges in the future of the Bremerton water system as described
in this plan are:
. Providing appropriate water supply and infrastructure to meet the
anticipated growth in the water service area,
. Maintaining compliance with current and future water quality regulations
as required by the Safe Drinking Water Act,
. Communicating effectively with water customers about the value of their
water system to increase customer understanding, confidence, and support.

Introduction and Water System Description
1.1 Introduction
The City of Bremerton has a remarkable resource: a clean, abundant water supply. The
Bremerton Water Utility supplies approximately 3 billion gallons of water each year to over
56,000 people. This represents over a third of all the drinking water supplied in Kitsap County.
Bremerton's Group A water system is a municipally-owned water utility under the direction of the
City ofBremerton Department of Public Works and Utilities. Bremerton Municipal Code (BMC)
Title 15 regulates City Utility operations to provide safe, reliable service to the residents of the
City of Bremerton and to those non-residents within the service area. These utility operations
include water, wastewater, and stormwater. The Water Utility is managed as an enterprise fund in
the City's budget. The water service area consists of the Bremerton city limits and portions of the
surrounding unincorporated area in Kitsap County. Approximately 80 percent of the water is
used within the city limits (includmg "Navy systems), and 20 percent is used in the unincorporated
areas. All customers are represented by the Bremerton City Council, Bremerton Water Utility's
governing body.
The Bremerton Water Utility owns and operates two water systems. Additionally, the Bremerton
Water Utility has contractual requirements to provide water supply, operations, and maintenance
for the Rocky Point Water District, supply all the water to the Puget Sound Naval Shipyard and
Jackson Park Naval Housing water systems, and sell water to the City of Port Orchard as outlined
in Table 1-1 below.

operated by the City of Bremerton. Since the W517 Zone is a small non-transient, non-
community system, it is only required to prepare a small water system plan; however, since it is
operated in conjunction with Bremerton's main system, its planning information will be included
in this Water System Plan. Copies of the Water Facility Inventory form for both systems are
included in the Appendices. Other water systems purchasing water from the City of Bremerton
are responsible for their own water system planning (see Table 1-4).
1.2 Water System Planning Objectives
The purpose ofa Water System Plan is to provide a uniform process for purveyors to:
· IdentifY present and future needs,
. Set forth the means for addressing those needs, and
· Demonstrate the system has the operational, technical, managerial, and financial capability to
maintain compliance with all relevant local, state, and federal plans and regulations.
Bremerton is required to develop a WSP according to Chapter 246-290-100 Washington
Administrative Code (WAC) and by BMC Section 15.02.020. This WSP is to be approved by the
Mayor, adopted by the City Council, and administered by the Director of Public Works and
Utilities. All anticipated water system projects should be identified in the Capital Improvement
Program portion of the WSP. Information contained in the WSP should be referenced when
proposing new facilities or modifications to new facilities.

1.3 Water System Plan Background
Previous WSPs were completed in 1975, 1982, 1992, and 1999. The last plan was approved by
the Washington Department of Health (DOH) in December 2000. This 2005 WSP update was
prepared in accordance with DOH regulations (WAC 246-290), the DOH "Water System
Planning Handbook", and the 2003 Municipal Water Supply Efficiency Requirements Act, and
was also coordinated with the City of Bremerton Comprehensive Plan, the Kitsap County
Comprehensive Plan, and the Kitsap County Coordinated Water System Plan.
The following changes have occurred since the 1999 WSP was completed:
· The Risk Management Plan for Chlorine in compliance with 40 CFR 68 Clean Air Act required
that the Environmental Protection Agency (EP A) implement a program to manage and
prevent accidental releases of hazardous substances. Bremerton completed the requirements
for this regulation in 1999 and is in compliance with all updates.
· Implementation of the 1998 Washington State Watershed Management Act began in the
Kitsap Peninsula in 2000 but this water planning process was halted in 2005 due to a veto
from the Squaxin Island Tribe.
· The Bremerton West 51 T Zone was designated as a separate water system in 2001.
· The United States Congress passed the Public Health Security and Bioterrorism Preparedness
and Response Act of 2002. A Vulnerability Assessment and Emergency Response Plan were
developed for the Bremerton water system in compliance with this act.
· Passage of the Washington State Municipal Water Law in 2003 requires water systems to
implement more specific water efficiency measures and requires more coordination of water
planning between state and local agencies.
· The Tracyton Water System was assumed by the City ofBremerton in 2004.
· The Kitsap County Coordinated Water System Plan was updated in 2004.
· An agreement with the City of Port Orchard in 2005 specifies wholesale water sales from
Bremerton and coordination of the West 580 Pressure Zone development.

1.4 Bremerton Water System History
When the town of Bremerton was incorporated in 1901, with a population of 1,000, drinking
water came from local wells and streams. The City of Bremerton has had a public water supply
system since 1902, when a private water company, The Pacific Coast Pipe Company, diverted
water from Charleston Creek. The Anderson and Gorst Creek sources were developed in 1909
and 1911, respectively. The City of Bremerton purchased the 2 million gallons per day (MGD)
water system in 1917 for $225,000.
Growth of the Puget Sound Naval Shipyard and the City after World War I required significant
improvements to the water system. In 1919, storage for 10 million gallons (MG) was added with
the construction of Reservoir 4. The Union River was considered as a future water supply
source. In the 1930's, 2,800 acres of the Gorst Creek watershed and 2,200 acres of the Union
River watershed were purchased by the City. Development of the Anderson Creek wellfield
began in 1940 to meet increased demands of World War II shipyard activity. Reservoir 4's
capacity was increased to 11 MG in 1945. Casad Dam on the Union River was completed in
1956. Use of Charleston, Gorst, and Anderson Creeks as potable water supplies was
discontinued in 1963, 1979, and 1984, respectively. Gorst and Anderson Creeks are still
maintained as emergency water supplies. Since the late 1970s, the City has been developing
ground water sources in East Bremerton and the Gorst Creek Basin, and in 2005 rehabilitation of
the Anderson Creek well field was completed.
In 1992, Bremerton received approval from DOH to continue to operate the Union River surface
water supply as an unfiltered source. Bremerton is one of only a few systems nationwide that can
meet the strict water quality requirements (which are described in Section 4) and is approved to
operate an unfiltered surface supply. In 2001, DOH designated the West 517 Zone as a separate
Water System Description

water system. In 2004 the Tracyton Water District service area was assumed by the Bremerton
Water Utility.
1.5 Overview of Existing System
The City of Bremerton draws water from a large surface water reservoir on the Union River and
thirteen wells. Water is distributed to customers via approximately 300 miles of water pipe
varying in size up to 36 inches in diameter. Pump stations move water from pressure zone to
pressure zone and distribution system reservoirs provide storage. Booster stations and pressure
regulating stations control service pressures within the system. Facility locations are shown in the
Schematic (Figures I-2a-b) and Water System Map (Figures I-3a-c). A summary of the
Bremerton water system is provided in Table 1-2. Detailed descriptions and inventories are
provided in the following sections.

2005 City of Bremerton Water System Plan
1.5.1 Sources of Supply
Surface Water
Approximately 60 percent of the water supply for the City of Bremerton is provided by
the Union River system. The main source is the Union River Reservoir, located behind
Casad Dam, a concrete arch structure that rises 130 feet above the river and provides
approximately 1.4 billion gallons of water storage. Water flows from the reservoir down
the natural streambed to the McKenna Falls Intake Facility. Three branches of the Union
River meet near the Intake Facility. Water from the Union River and West Branch (used
seasonally) is blended at the McKenna Falls Intake Facility, where it is screened and
cWorinated. Water then enters the transmission main and flows to the distribution
entrance point at Reservoir 4, where it is treated with sodium hydroxide for corrosion
control. Flow is controlled by a valve at Casad Dam, a flow control valve on the
transmission main near the Twin Lakes Reservoir, and by the level in Reservoir 4. Since
1992, the East Branch of the Union River no longer enters the intake but continues
downstream to meet downstream flow requirements.
Bremerton owns and controls 98 percent of the 2,964-acre Union River watershed that
supplies the McKenna Falls Intake Facility. This allows the City to effectively control the
activities in the watershed and protect source water quality. The estimated firm yield for
the Union River System is 2,020 million gallons per year (MGY).
The City of Bremerton actively protects its watersheds through the provisions 'in the
Watershed Control Plan and the Bremerton Land Management Plan, which include
security and monitoring provisions. The accessible areas of the watersheds are fenced,
gated, and signed to limit access only to authorized personnel. The area is regularly
patrolled to ensure trespassing is kept to a minimum. Regular water quality monitoring of
the surface sources verifies the effectiveness of the watershed protection program for the
City. The City operates the surface system under the non-filtration requirements of the
Surface Water Treatment Rule (SWTR). To continue to operate the Union River source
as an unfiltered supply, Bremerton is required to conduct an annual sanitary survey by
DOH and submit an annual watershed monitoring report to DOH documenting
compliance with the unfiltered source criteria of the SWTR.
Water quality of the surface sources is excellent. Turbidity is continuously monitored and
is generally below 1 Nephelometric Turbidity Unit (NTU). Higher turbidity levels do
occur during heavy rains; however, these events are usually of short duration. When
turbidity approaches higher than desirable values, the water to the intake is shut down, and
the water either bypasses the intake or is stored in the Union Reservoir until sufficient
settling occurs. High turbidity water from the West Branch is not allowed to enter the
system and passes downstream. Raw water coliform testing confirms that fecal coliform
concentrations are less than 20 colonies/100 mL in 90 percent of the samples collected
over any 6-month period. With the redundant cWorination facilities, automatic system
shutdown capabiiities, and bypassing of turbid water, water quality of the surface source
meets all Safe Drinking Water Act (SDWA) requirements.
Water System Description
1-6
2005 City of Bremerton Water System Plan
To comply with the SWTR, cWorine contact time (CT) values are calculated according to
WAC 246-290-636. Chlorine residual is monitored continuously at the Twin Lakes valve,
Pump Station 3, Gorst Monitoring Station, and Reservoir 4. For process control, a
minimum cWorine residual of approximately 1.4 milligrams per liter (mg/L) is maintained
at the entrance to the transmission system at the McKenna Falls Facility, and a minimum
cWorine residual of approximately 1.0 mg/L is maintained at the entrance to the
distribution system at the Reservoir 4 inlet. The State requirement is a minimum of 0.2
mg/L at the entrance to the distribution system with detectable cWorine residual
throughout the distribution system. CWorine grab samples are taken at points in the
distribution system at the same times and locations as coliform samples.
Prior to entering Reservoir 4, the pH of the water is increased with sodium hydroxide at
the Corrosion Control Facility (CCF) in accordance with 40 CFR Part 141.83. The target
pH value is 7.7 standard units (SU). The CCF began operating in March 1999.
Distribution system pH and customer tap lead and copper monitoring verifies the
effectiveness of the corrosion control treatment.
Groundwater
The City of Bremerton's main system currently has ten active production wells supplying
approximately 40 percent of the water to the system. The West 517 Zone system has
three wells serving that system. The City completed two other wells (Wells 21 and 22)
not yet been put into production pending water rights approvals and two replacement
wells at Anderson Creek. The wells (described in detail in Table 3-1) are generally located
in three groups: East Bremerton wells, Anderson Creek watershed wells, and Gorst Creek
watershed wells. The locations of the wells within the system are shown on the Water
System Map and Schematic (Figures 1-2 and 1-3). Most wells pump directly into the
system during operation and are controlled through the Supervisory Control and Data
Acquisition (SCADA) system by the level in the reservoir(s) they supply. Anderson Creek
wells pump into a common sump, and discharge into the system is controlled by system
operators. Water quality in the wells is excellent. Each well, with the exception of Well
19, is equipped with cWorination facilities for disinfection.
The eight aquifers the City draws drinking water from are:
· Anderson Creek Shallow Artesian Aquifer
· Anderson Creek Deep Artesian Aquifer
. Twin Lakes Aquifer
· Gorst Sea Level Aquifer
. Gorst Valley Aquifer

Aquifer characteristics are more thoroughly discussed in Bremerton's Wellhead Protection
Plan (1996) which was previously submitted to DOH.
Water Rights
Water rights are discussed in Section 3, Sources of Supply.
1.5.2 Hydraulic Gradients and Pressure Zones
The City of Bremerton operates eight major hydraulic gradients or pressure zones within
the distribution and transmission network. Seven pressure zones are in the main system:
four zones in West Bremerton (W256, W440, W580 and W650) and three in East
Bremerton (E240, E398, and E490). One pressure zone is in the West 517 Zone system.
The number designation refers to the overflow elevation of the controlling reservoir(s).
These pressure zones are illustrated in the Water System Map (Figure 1-3). Hydraulic
gradients within the zones are generally controlled by the water levels in the system
reservoirs. Service pressures within the zones are maintained at acceptable levels under
normal, peak, and emergency operating conditions.
Pressure regulating valves are described in Section 5 and include installations for reducing
pressure and pressure relief Pressure reducing stations allow water to flow from higher
pressure zones to lower pressure zones as needed. Pressure relief valves prevent over-
pressurization by relieving excess pressure to atmosphere or to a lower pressure zone.
1.5.3 Storage Facilities
The City of Bremerton currently operates 19 reservoirs (16 distribution and 3 raw water)
in the Main System and two reservoirs in the West 517 Zone System. These reservoirs
range in storage volume from the Union River Reservoir behind Casad Dam to Reservoir
6, a 0.15 million gallon (MG) elevated steel tank. The reservoirs are described in detail in
Section 5 and provide peak demand storage, emergency and fire flow reserve, and
hydraulic gradient control for the system. A total of 32 MG of storage capacity presently
exists within the Main System and l.2MG in the West 517 Zone System.
When it is full, the Union River Reservoir provides 1,400 MG of water in storage for the
system. Excess water from the Union River canbe diverted to the Twin Lakes Reservoir;
however, the Twin Lakes reservoir does not directly provide storage to the system. The
Twin Lakes Reservoir sits on a hydrogeologic divide and has no natural outlet. Its water
seeps into the ground to provide groundwater recharge to both the Gorst Creek
Watershed wells and to the Union River drainage.
1.5.4 Pump Stations.
Bremerton operates pump stations ranging in size from 60 gpm to 4,000 gpm.
Descriptions of the existing pump stations are listed in Section 5. The pump stations
move water from lower pressure zones to water storage reservoirs in higher elevation
pressure zones. Booster stations increase the pressure in a limited area to adequate
Water System Description
1-8
2005 City of Bremerton Water System Plan
pressures. These stations are required to ensure an adequate supply of water at acceptable
pressures to all customers in the system.
1.5.5 Transmission and Distribution Piping
Bremerton has an extensive network of transmission and distribution piping ranging in size
up to 36 inches in diameter. The pipe inventory lists approximately 300 miles of pipe with
the majority being 6-inch or 8-inch diameter distribution piping. A listing of the quantity
of pipe by diameter is provided in Section 5.
Transmission main piping is used to move large quantities of water from one area of the
system to another, generally without service connections. It includes the piping bringing
water from the McKenna Falls Intake Facility and the three pipes crossing the Port
Washington Narrows to supply the east side of the system.
The distribution system serving the City of Bremerton is a grid of 4-inch to 16-inch mains
comprised of cast iron, ductile iron, polyvinyl chloride (PVC), steel, galvanized steel, and
asbestos cement materials. Ductile iron and cast iron pipe make up the majority of the
system. Flow within the system is generally from west to east. The system contains fire
hydrants and valves to provide Utility customers with fire protection.
1.5.6 Telemetry and Controls
The City ofBremerton utilizes a sophisticated SCADA system to monitor and control the
water supply and distribution system. A central computer and two master telemetry units
(MTUs) are located at the Public Works and Utilities office. Additional information on
the SCADA system is provided in Section 6.
1.6 Existing/Future Service Area
Figure 1-4 shows the City ofBremerton Water Utility service area. The City ofBremerton Water
Utility's main system serves over 56,000 residents in Bremerton and portions of Kit sap County,
including the Gorst area to the south and the western portion of the Manette Peninsula in central
Kitsap County from the city limits to Bucklin Hill Road. The West 517 Zone service area
includes the Gold Mountain Golf Course, Aero Mobile Estates (master metered), Bremerton
National Airport, and the Port of Bremerton Industrial Park. The City also provides water and
operations and maintenance to the Rocky Point Water District and contracts to supply water to
the Puget Sound Naval Shipyard and Intermediate Maintenance Facility (PSNS&IMF) and the
City of Port Orchard. (Refer to Tables 1-3 through 1-5 for details on water service agreements.)
The current service area includes approximately 5,300 acres within the Bremerton city liinits, not
including PSNS&IMF. Bremerton serves approximately 6,800 acres within Kitsap County,
including the Rocky Point Water District. As shown on Figure 1-4, the City ofBremerton Water
Utility service area is essentially contiguous with the surrounding water purveyors as follows:
· North - Silverdale Water District and Erland Point Water Company
· South - The City of Port Orchard and the Sunnyslope Water District
Water System Description
1-9
2005 City of Bremerton Water System Plan
· East - North Perry Avenue Water District
· West - Unclaimed service area
1.6.1 Service Area Agreements
The Utility has written service area agreements on the boundaries between their respective
service areas with:
· Erland Point Water Company
· North Perry Avenue Water District
· Rocky Point Water District
· Silverdale Water District
· Sunnyslope Water District
Currently, Bremerton is in the process of developing a written service area agreement with
the City of Port Orchard. Tables 1-3, 1-4, and 1-5 summarize the agreements between the
City ofBremerton Water Utility and other water systems.
Growth in the service area is expected to occur in the area north of the city limits in the
Manette Peninsula, south of the city limits near the Bremerton Airport, south of Werner
Road, and west of Kit sap Lake. Population projections and land use are described in more
detail in Section 2.
The City currently pursues annexation of areas on the edges of the city limits. The
Outside Utilities Agreement must be executed prior to receiving water service outside city
limits in accordance with the Bremerton Service Area policy that requires property owners
outside the City boundaries to support annexation to the City ofBremerton as a condition
for receiving City utilities (see Section 1.7.3).

1.6.2 Service Area Characteristics
The service area is located within the Puget Sound Lowland. Geologic uplifting of the
Cascade and Olympic Mountain ranges formed the Puget Sound Lowland. Erosion of
these mountain ranges deposited sedimentary materials in the lowlands, and glaciation
carved the low rolling hills, scattered lakes, islands and inlets. The Vashon Drift,
composed of unconsolidated silts, sands and gravels, was deposited about 13,500 years
ago by an ice sheet known as the Vashon Glaciation that advanced from Canada. These
deposits are as much as 3,000 feet thick and normally are divided into three units. The
upper and lower units consist of glacial drift deposited by the ice or glacial meltwater and
are composed mostly of layers of sand and gravel alternating with layers of silt and clay.
The middle unit consists of a non-glacial deposit of silt and clay that normally ~eparates
the other two units. The thickness of the upper unit is normally 200 to 400 feet. The
middle unit ranges. up to 260 feet, but is commonly between 10 and 80 feet thick. The
thickness of the lower unit is estimated to be between 2,000 and 3,000 feet.
The topographic features and waterways are generally oriented on a north-south axis
corresponding to the orientation of the Cascade and Olympic Mountain ranges and the
direction of advance. and retreat of the Vashon Glaciation. Lands range from sea level to
over 600 feet in elevation and include forested regions to the west in the vicinity of the
Union River and Gorst Creek Watersheds. Bordering the marine shoreline are moderate
to steep, irregular cliffs carved first by glaciation and then by erosion. Steep slopes also
border the numerous small stream valleys that were the sites of glacial-melt water streams.
The average annual precipitation vanes, but is generally between 45 and 50 inches per
year in the City and about 60 inches per year in the Union River Watershed area.
1.7 Service Area Policies
Bremerton has a legislatively-mandated "duty to serve" within its water service area, as
designated in Figure 1-4. Section 3 describes how Bremerton determines adequate water capacity
to serve additional customers. The Bremerton Water Utility procedures for processing water
service requests are contained in the Kitsap County Coordinated Water System Plan (CWSP) and
the Bremerton Municipal Code.F ollowing is a summary of adopted policies/ordinances relating to
the Bremerton Water Utility service.
1.7.1 Kitsap County Resolution Adopting the Coordinated Water System
Plan
Resolution No. 090-2005, dated May 9,2005, adopts the latest update of the CWSP. The
first CWSP was completed by the Water Utility Coordinating Committee in 1992. The
resolution was adopted subject to a specific purpose, goals, and policies. The purpose of
the CWSP is to maximize the efficiency and effectiveness of water service in the County
by defining service areas within which utilities accept responsibility for providing service.
Goals and policies set forth pertain to coordinated planning, water supply and distribution,
planning and design standards, and appeals.
Water System Description
1-14
2005 City of Bremerton Water System Plan
1.7.2 Bremerton Municipal Code Regulating City Utility Operations
Bremerton Municipal Code (BMC) Title 15 regulates City Utility operations to provide
continued safe, reliable utility service to City of Bremeron residents and those non-
residents the City agrees to serve. These utility operations are water, wastewater, and
stormwater. General Utility provisions are listed under BMC Section 15.01, and Water
Utility provisions are located in BMC Chapter 15.02. In summary, Title 15 includes
general provisions such as operations, utility service agreements with customers of the
Utility, conditions of service, penalties for false information, developer system
improvements, system development and construction standards for modification or
improvement, and utility permit requirements. The authority of the Water Utility includes
adopting, establishing, and enforcing standards, rules, and regulations; developing and
implementing comprehensive planning; recommending rates and charges; and providing
utilities and contract services.
BMC Chapter 15.02 includes subsections concerning development of a water system
comprehensive plan, service availability, service beyond city limits, construction standards,
abandonment of private mains, private pressure adjustment, hydrants, irrigation and fire
service metering, service connections, connection size, meters, backflow and cross-
connection control, water system operation and maintenance, interruption of service for
emergencies, abatement of nonconforming unauthorized or unsafe conditions, cross-
connection control inspection, meter operation and maintenance, excessive consumption,
waste of water, prohibited acts, assessments, rates, fees and charges, billing, and appeals.
1.7.3 Outside Service Area Policy
The Outside Utilities Agreement is a recorded document which must be executed prior to
providing water service outside city limits and is an element of the Bremerton service area
policy. The BMC requires property owners outside the City boundaries not to oppose
annexation to the City of Bremerton as a condition for receiving City utilities. Potential
outside-of-city customers who do not wish to support annexation have the following
options:
. Drill their own well in compliance with County requirements,
. Be served by another public water system,
. Construct a new public water system operated by an approved satellite system,
management agency according to the rounty Coordinated Water System Plan policy
and state regulations, or
. Not proceed with a proposed water-dependent development.

2005 City of Bremerton Water System Plan
Section 2
Planning Background Information
2.1 Existing/Future Service Area
The City of Bremerton Water Utility serves approximately 57,000 residents in its water supply
area, which includes the Bremerton water service area (city limits and portions of unincorporated
Kitsap County) and other areas with service agreements. These areas were described previously
in Section 1, Table 1-1 and Figure 1-4 (service area map). Continued growth is anticipated
within the current service area. Approximately 90 percent of the Bremerton service area lies
within an Urban Growth Area (UGA). UGAs are specifically designated for growth at urban
densities.
Service areas - both retail and wholesale - are determined through a process described in the
Kitsap County Coordinated Water System Plan (CWSP). Retail water service area boundaries
are established by agreement between the water purveyors. Bremerton has service area
agreements with all adjacent water providers with the exception of the City of Port Orchard,
which is still under discussion. The CWSP provides the legal mechanism for water utilities to
establish an exclusive retail service area. A designated retail service area denotes a specific utility
has accepted responsibility for development of cost-effective and efficient water service to
accommodate the future growth these areas will experience. Growth management objectives
established for these areas must be accounted for in each utility's approved Water System Plan.
The establishment of retail water service area boundaries carries two obligations:
1. The county and state governments recognize an identified utility as responsible for providing
all retail public water service within a designated area, and
2. The designated utility shall assume responsibility within its service area for planning and
implementing water system development and proper utility management.
2.1.1 Bremerton Service Area within City Limits
The entire City of Bremerton is within the "Bremerton UGA." Although most land within
the City is already developed, Bremerton is planning for significant growth through infill.
The City of Bremerton 2004 Comprehensive Plan lays a foundation for an increase of
about 12,000 people between 2004 and 2023. The Comprehensive Plan proposes changes
iIi the comrnunity design ethic, as well as emphasis on regulatory incentives. Bremerton
is anticipated to attract a larger percentage of the population growth than in the past. The
Comprehensive Plan's key urban design model is "The Centers Concept," a mixed-use
urban village approach to planning. Population growth for the City is largely calculated
on the ability of strategically-placed, mixed-use activity centers to attract new residential,
commercial, and industrial uses.
Planning Background Information
2-1
2005 City of Bremerton Water System Plan
Approximately 58 percent of the City's growth is expected in the new "Neighborhood" or
"District Centers." Bremerton will position itself to attract development requiring the
modification of existing zoning categories to provide sufficient industrial, commercial,
and mixed use lands for business opportunities. The "Centers" approach builds on the
City's initial focus on the Downtown Regional Center.
Initially, growth will continue to focus on urbanizing neighborhoods on the edges of
Bremerton. This pattern is most evident along the Highway 303 corridor north to the
Silverdale area. In addition to Bremerton's Urban Growth Area, the City recognizes that
its long-term health is tied to a larger area of interest, identified in Figure 2-1 as the
Eventual Growth Proposal Map. Existing and future urban areas in Kitsap County, under
growth management precepts, should be associated with a city.
2.1.2 Bremerton Service Area in Unincorporated Kitsap County
Much of the unincorporated part of the Bremerton service area has experienced
significant growth in recent years. This trend is expected to continue into the future,
particularly in those portions within a UGA, such as:
. North Manette Peninsula - The area north of the city limits and south of Waaga
Way within portions of both the Bremerton East and Central Kitsap UGAs.
. Sherman Heights/Navy Yard City Area - An area south of the west Bremerton city
limits and north of Gorst, which is within the Bremerton UGA.
. South Kitsap Industrial Area (SKIA) - The Bremerton National Airport and the
Olympic View Industrial Park are designated as a stand-alone unincorporated joint
planning area.
e Gorst - An existing commerciallindustrial area at the head of Sinclair Inlet, which is
designated as the Gorst UGA.
2.1.3 land Use
Figure 2-2 shows comprehensive plan designations in the Bremerton water service area
indicating what type of development is authorized for the property. Excluding the City's
watershed and utility lands, a breakdown of generalized future land use categories
follows. Approximately 54 percent of the service area consists of urban single-family
residential land use. Roughly 1 percent of the service area consists of single-purpose
multi family residential land use. Twelve percent of the service area is designated for
mixed-use commercial and residential "centers" land uses, and an additional 5 percent is
designated for single-purpose commerciaL Industrial land uses comprise a total of 23
percent of the water service area and open space and parks make up roughly 5 percent of
the service area. Industrial areas include the greater South Kitsap Industrial Area (SKIA)
and the Puget Sound Naval Shipyard.

2005 City of Bremerton Water System Plan
2.2 Related Plans and Requirements
Several other existing plans and requirements must be considered in the planning of a water
system in Washington State, as described below.
2.2.1 City and County Comprehensive Plans under the Growth
Management Act
The state legislature passed the Growth Management Act (GMA) in 1990 to require
coordinated planning for projected growth in the faster-growing counties in the state. The
GMA emphasizes control of "urban growth," including the type of growth, its intensity
and location, and the utilities and services it needs. The GMA requires all urban counties
and their cities to develop and adopt 20-year comprehensive plans, along with regulations
to implement those plans. The plans must address specific issues, including but not
limited to, land use, transportation, housing, capital facilities and services, natural
environment, and economic development. The act has been amended in subsequent
legislative sessions.
The GMA requires local plans to be consistent with GMA requirements. If the
comprehensive plan cannot show the provision of adequate public facilities and services
to supply new development, the plan must be changed to allow only the amount of
development that can be provided with adequate public facilities and services. Sanctions,
including withholding of certain state revenues, are authorized for non-compliance with
the GMA. Highlights of the GMA, as it pertains to water plans, are described below:
. Urban growth. Encourage development in urban areas where adequate public
Jacilities and services exist or can be provided in an efficient manner.
. Reduction of sprawl Reduce the inappropriate conversion oj undeveloped land into
sprawling, low-density development.
. Economic development. Encourage economic development throughout the State that
is consistent with adopted comprehensive plans., Promote economic opportunity Jor
all citizens oj this State, especially Jor unemployed and Jor disadvantaged persons,
and encourage growth in areas experiencing insufficient economic growth, all within
the capacities oJthe State's natural resources, public services and public Jacilities.
. Permits. Applications Jor both State and local government permits shall be processed
in a timely and Jair manner to ensure predictability.
. Environment. Protect the environment and enhance the State's high quality oj life,
including air and water quality, and the availability oj water.
. Citizen participation and coordination. Encourage the involvement oj citizens in the
planning process and ensure coordination between communities and jurisdictions to
reconcile conflicts.
. Public facilities and services. Ensure that those public Jacilities and services
necessary to support development shall be adequate to serve the development at the
Planning Background Information
2-5
2005 City of Bremerton Water System Plan
time the development is available for occupancy and use without decreasing current
service levels below locally established minimum standards.
. Capital facilities. GMA cities and counties must demonstrate that they can afford the
infrastructure needed to support expected growth. If the services cannot be provided,
the land uses must be revised or the levels of services (LOS) reduced.
. Comprehensiveness. Comprehensive Plans must integrate planning for land use,
housing, transportation, capital facilities and utilities. All areas of cities and counties
and all plan elements must be addressed from an area-wide perspective.
. Consistency. Comprehensive plans must avoid internal contradictions and must not
interfere with the successful implementation of the plans of neighboring jurisdictions.
Plan policies must be consistent with the direction established by the GMA, Vision
2020 and adopted county-wide planning policies.
The GMA requires counties to establish "Urban Growth Areas" (UGAs) to help guide
urban growth into the most appropriate areas and to reduce urban sprawl. Kitsap County
has established several UGAs, including UGAs in the greater Bremerton area. Some
UGAs are associated with an incorporated city, and some UGAs in the greater Bremerton
vicinity are "unassigned." Unassigned UGAs are found north of Riddell Road in East
Bremerton and south of the City in the South Kitsap Industrial Area and other areas such
as Gorst. UGAs associated with the City of Bremerton may be annexed into the City at
any time. Unassociated UGAs are intended for urban-style development, but are not as
likely to be annexed into a city without prior association of the UGA with that city. The
following identifies UGAs in the greater Bremerton area and their associations.
Regardless of association, substantial portions of some or all of these UGAs will be
provided water service by the Bremerton Water System.
Greater Bremerton Urban Growth Areas:
. Bremerton West - Includes unincorporated areas adjacent to West Bremerton such
as Navy Yard City and the Sunnyhill Road unincorporated "island."
. Bremerton East - Extends north of East Bremerton to Riddell Road.
. Central Kitsap - Unassigned. Extends north of Riddell Road to the Silverdale
UGA.
. Gorst - Unassigned. Includes the urbanized area at the head of Sinclair Inlet.
. McCormick Woods - Unassigned. Extends south of the former Northwest
Corporate Campus to the McCormick Woods golf course and nearby residential
development.
. Port of Bremerton/South Kitsap Industrial Area - Unassigned. Extends south of
the Bremerton Watershed to the Bremerton Industrial Area and Airport.
In addition, the County has established several "Urban Joint Planning Areas" - areas
designated as Urban Reserve or Urban Industrial Reserve that may be needed to support
future growth. These areas will be subject to coordinated planning to determine how each
area should be configured, designed, serviced, financed and/or governed.
Planning Background Information
2-6
2005 City of Bremerton Water System Plan
These joint planning areas are located adjacent to City of Bremerton UGAs and within the
Bremerton water service area.
Greater Bremerton Joint Planning Areas:
. Port Blakely/ Kitsap Lake South - An area southwest of Kitsap Lake adjacent to the
City of Bremerton incorporated Port Blakely properties west of Kitsap Lake.
. Gorst Area Urban Reserve - Areas immediately west and north of the Gorst UGA
extending toward the Navy Yard City.
. West McCormick Woods - Areas adjacent to the McCormick Woods UGA to the
west and south and extending toward the Gorst UGA.
The GMA requires cities and counties to enter into agreements for ongoing coordination
of their comprehensive plans. Agreements must specify how all major aspects of urban
development will be managed, including the extension of utilities and other urban
services. Under the GMA, the City of Bremerton, the City of Bremerton Water Utility,
and Kitsap County must coordinate their comprehensive plans and water supply plans.
In 1992, Kitsap County adopted countywide planning policies spelling out the County's
intent to develop "Urban Growth Management Agreements" (UGMAs) with other
jurisdictions to coordinate planning and growth activities within established UGAs. The
City of Bremerton and the County have not yet developed an UGMA for the Bremerton
UGA. To ensure coordination of public facilities, the UGMA will contain at least the
following provisions:
. Establish a method of sharing net revenues, services, and expenses (if appropriate) in
annexations of significantly developed areas.
. Consider pre-annexation agreement issues related to the provIsIOn of urban
governmental services.
. Designate level of service (LOS) standards.
. Identify services to be provided in the UGA, the reasonable purveyors, and the terms
under which the services will be provided.
The City amended the Bremerton Comprehensive Plan in 2004, which includes a Capital
Facilities Element and six-year Capital Facilities Plan (CFP). The CFP is a six-year
finance plan that identifies expected costs and sources of funding for needed facilities,
including water facilities. The CFP must be amended annually to stay in compliance with
the GMA.
Kitsap County submitted its Comprehensive Plan to the state in December 1994, but it
was appealed to the CentralPuget Sound Growth Management Hearings Board and
declared invalid in 1995. The County adopted a revised plan in 1996, which was declared
partially invalid in 1997. This was followed by the most recent plan adopted in May
1998, and in February 1999 the Hearings Board rescinded the invalidation. Non-
compliance issues regarding joint planning areas were resolved in November 1999 in all
areas with the exception of the Port Gamble Joint Planning Area. The County's 1998
Comprehensive Plan was amended in 2002, 2003, and 2004.
Planning Background Information
2-7
2005 City of Bremerton Water System Plan
To be consistent with the GMA, the Bremerton WSP must address how the City plans to
provide water to expected new residents over the next 20 years. The WSP includes a
, '
financing plan for water facilities. Information from the plan will be summarized and
included in the City's CFP during each annual update. The water financing plan will be
updated annually, consistent with the GMA. The annual updates will supersede the WSP
financial plan during interim years until the WSP is again updated.
2.2.2 Municipal Water Law
In addition to the importance of conserving water for fish, growing communities,
agriculture, and industry place an increasing demand on Washington State's water
resources. To help meet these growing needs, the state legislature passed the Municipal
Water Supply-Efficiency Requirements Act, commonly called the Municipal Water Law
(MWL). The MWL amended sections of the State Board of Health Code, the laws
governing public water systems, and sections of the State's Water Code. These changes
affect the water system planning process, provide greater certainty and flexibility for
water rights held by public water systems, and more closely tie water system planning and
engineering approvals by the Department of Health to water rights administered by the
Department of Ecology.
The MWL allows for the expansion of the place of use of a municipal water supplier's
water right to all areas included in its service area, as described in an approved WSP.
Expansion of the place of use on a water right through an approved WSP now requires
local government consistency determinations. Consistency determinations should reflect
the water system's entire service area. The MWL requires DOH to ensure consistency
with local adopted plans, regulations, and polices (including CWSPs) and establishes a
municipal water supplier's duty to serve within its retail service area. Ensuring local
government consistency is the responsibility of the water system.
Sections of the MWL pertaining to water system planning are:
. Municipal water supplier definition - Provides the definition of a municipal water
supplier and establishes municipal water supply purposes.
. Water right connection/population limitations - Clarifies the State's Water Code
by stating that the number of water service connections and population are not
limiting attributes of water rights for water systems that have a DOH approved water
system plan or other approval that specifies the number of connections.
. Plan review coordination between DOH and the Department of Ecology
(Ecology) - Amends the State's Water Code directing DOH and Ecology to
coordinate WSP approval procedures with water right determination procedures for
WSPs.
o Service area consistency - Allows a municipal water supplier to expand the place of
use on its water right to all areas included within the service area described in its
approved WSP. This benefit is provided if the water right holder is in compliance
with the terms of its WSP, and the service area is consistent with applicable approved
comprehensive plans, land use plans, development regulations, coordinated water
Planning Background Information
2-8
2005 City of Bremerton Water System Plan
system plans, and watershed plans. Place of use is not reduced if the service area
identified in an approved WSP is smaller than the place of use in the water right.
. Conservation requirements - Provides direction on conservation to municipal water
systems with 1,000 or more connections. This includes reporting the conservation
measures the utility has put into practice in the past and how those measures have
increased its water use efficiency.
. Current conservation programs and the conservation rule - Directs DOH to
develop water conservation rules expected to be finalized in 2006 and to involve key
stakeholders in the process. Municipal water suppliers are to continue to meet current
conservation planning requirements and implement their current programs.
. Local government consistency and duty to serve - Requires new services within a
water system's service area to be consistent with applicable, approved local land use
plans, comprehensive plans, and development regulations. Water utilities must
delineate retail service areas in their WSP. Water systems with DOH-approved WSPs
now have a duty to provide service to new connections within their retail service area.
. Reclaimed water-Requires systems serving 1,000 connections or more to evaluate
reclaimed water opportunities.

2.3 Population Estimates for the Bremerton Water Supply Area
The residential population estimates for the Bremerton water supply area are presented in Table
2-2 and Figure 2-3 and include estimates for years 2000 to 2004, forecasts for years 2005 to
2024, and methodology used. The forecasted population used for this WSP is about 12 percent
lower than the forecast required for use in the 1999 WSP.
The Bremerton water supply area consists of service areas requiring population information for:
. Bremerton Retail Water Service Area - City and adjacent unincorporated areas
. Puget Sound Naval Shipyard and Intermediate Maintenance Facility
. Jackson Park Naval Housing
. Rocky Point Water District Retail Water Service Area
The West 517 Zone water system is not represented in this table, as it is designated a non-
community system without a significant residential population. Water use forecasts for that
system are discussed later in this section.
Several areas of proposed residential growth in the Bremerton Water Service area include:
Within City Limits:
. Waterfront Condominiums (W256 Zone). - In 2005, construction began on 144
condominium units in downtown Bremerton.
. East Park (E398 Zone)- This 40-acre area of former Navy housing was transferred to the
City of Bremerton and sold in 2005 to a developer who plans to construct 425 residential
units of single-family homes, condominiums, and apartments.
. West Hills (W440 and W650 Zones) - Over 400 acres are planned for development into
mixed use industrial and up to 450 residential units.
. Sinclair llidge (W580 Zone) - This 188-acre property in the Anderson Creek area was
previously considered for industrial/commercial development. In 2005 the property changed
ownership, and the current plan is to construct a residential development of approximately
1,500 single-family homes.
. Bayview (W580 Zone) - This 40-acre area is being developed for residential use.
e Port Blakely (W440 Zone) - This 440-acre development proposes mixed-use with a
projected 900 single-family equivalent units.
Currently Outside City Limits:
. Tracy ton (E240 Zone) - This 39-acre parcel was formally undeveloped land owned by the
Tracyton Water District. It was transferred to the Bremerton Water Utility as part of the
payment for assuming the water district in 2004. In 2005, the City sold the property to a
developer who plans to construct about 100 single-family homes.

2.4 Water Production and Demands
Production is defined as the total volume of water withdrawn from surface water and
groundwater sources for use in the Bremerton water supply area. Production is measured using
source meters on the surface supplies and wells. Bremerton water production since 1925 is
presented in Figure 2-4. Production since 1985 is presented in Table 2-3.

Water demand is defined as the quantity of water drawn from the water system by customers.
Demand is measured through the approximately 16,000 service meters located at each customer's
connection to the City's system. All services are metered. Navy contracted meters are read
monthly, and Water Utility personnel read the other residential and commercial meters every
other month. Water demand information is presented in Figure 2-5. Average day demand
(ADD) for the six years 1999 through 2004 is 7.7 MGD. In 2001, an extraordinarily dry winter
necessitated activation of the City's Water Shortage Contingency Plan to manage the drought.

2005 City of Bremerton Water System Plan
Navy properties include the Puget Sound Naval Shipyard and Intermediate Maintenance Facility
(PSNS&IMF) and Naval Station Bremerton, Jackson Park Housing complex, the Navy Hospital,
and several other smaller accounts. The largest demand in the entire system is PSNS&IMF,
which has an average water demand from 1999 to 2004 of 2 MGD, as shown in Figure 2-8.
Navy properties account for about one-third of Bremerton's water demands. Historically, the
Navy has had a significant effect on Bremerton's water system. It was due to increases in
workload at PSNS and the resulting increase in Bremerton's population that water demands
skyrocketed during World War II. This effect stands out when over 70 years of water production
is presented, as shown in Figure 2-4.
Within the PSNS&IMF the water uses are industrial/commercial (64%), shipboard (18%), steam
production (13%), and residential (5%). The Navy is performing two studies concerning water
conservation. First, a leak detection survey was completed indicating little water is lost through
leaks (approximately 2%). Second, a water conservation study with the goal of identifying
existing water uses and potential conservation projects within the PSNS&IMF is in progress. The
Navy expects its water demands to decrease over the next five to six years and then to stabilize
over the long range.

2.4.1 Maximum Day Demands
Maximum day demand (MDD) is defined as the highest amount of water used in a single
day in the calendar year. For Bremerton, these data are estimated using source production
meters.
Table 2-3 and Figure 2-9 present historical ADD andMDD. The ratio of MDD to ADD
for the past six years ranges from 1.65 to 1.96, which is in the expected range for
Washington water systems. This excludes the drought year of2001, which had a ratio of
1.53. The City implemented conservation outreach that summer, focusing on reduced
outdoor water use. The result was a 17 percent reduction in MDD.
Planning Background Information
2-16
2005 City of Bremerton Water System Plan
MDDs generally occur during summer warm, dry spells when outdoor water use is
highest; however, MDDs can also occur in the winter when customers let their taps drip
during freezing weather, PSNS activates its freeze protection system, and line breaks are
common. The highest MDD recorded for Bremerton in the past 25 years was 20 MGD,
which occurred on December 22, 1990 during a severe cold spell.
Forecasted MDDs are shown in Table 2-4 and Figure 2-9 and were calculated using a
MDD peaking factor of 2.0 as recommended by the Washington State Water System
Design Manual. This figure also shows the effect of further implementation of
Bremerton's conservation program in compliance with upcoming state efficiency
regulations.

2.4.2 Non-revenue Water
Non-revenue water is defined as the difference between metered source water and
metered water sales. Non-revenue water can include authorized uses such as water main
flushing, fire fighting, and hydrant flow testing or unauthorized uses such as leaks and
theft. Generally, systems having less than 10 percent non-revenue water are being
maintained properly. Since 1999, Bremerton's non-revenue water has averaged 5.7
percent of metered production, as shown in Figure 2-11, which indicates that water loss is
within acceptable levels.

2.4.3 Equivalent Residential Units
An Equivalent Residential Unit (ERU) is defined as the amount of water consumed by a
typical full-time, single-family residence. An ERU is a unit of measure to equate non-
residential or multi-family residential water usage to a specific number of single-family
residences. When ca1culatingERUs, only active accounts are considered. The amount of
water associated with an ERU is system specific. The ERU for one system will differ
from another based on demographics or water _ use patterns. An ERU for a particular
system can also change with time associated with changing water use patterns (such as a
lowering of ERU with conservation). Historical and projected water use in ERUs is
presented in Table 2~5. The ERUs forBremerton's system are presented in Table 2-7.

Use for Analysis 200
For analysis in this WSP, Bremerton will be using 200 gallons per ERU for ADD. This
value is on the low end of the range for water systems in Washington but reflects several
characteristics of Bremerton's system: including small lot size within the city limits, a
much higher percentage of rentals (60%) than the national average (40%), the fact that
one-half of Bremerton's residents are classified as low income, relatively high sewer
rates, and Bremerton's water conservation program.
2.4.4 Commercial/Industrial Demands
The Bremerton water supply area consists of approximately 1,400 commercial water
accounts, including commercial, government, and industrial entities. Other than activities
inside PSNS, the City has no large industrial users. The majority of businesses in the
water supply area consist of office-based businesses, restaurants, medical facilities,
automotive shops, and services (dry cleaners, beauty shops, etc.). The largest non-
residential water users are identified in Tables 2-8 and 2-9.
Sections 2.1.1 and 2.1.2 identify areas within the Bremerton water service area that are
anticipated to experience commercia1lindustrial development. These areas are also
described in Table 2-10.
2.5 Water Forecasts
As the population grows and commercial/industrial development occurs, demands on the water
system will increase accordingly. Water systems are required by DOH to prepare two forecasts:
one forecast without conservation and one forecast showing the expected reduction from
implementation of a conservation program. In 2003, the Washington State Legislature passedthe
Municipal Water Supply- Water Use Efficiency Requirements Act. The Department of Health is
expected to adopt water use efficiency regulations in 2006. These regulations will require water
systems to prepare Water Use Efficiency Plans (WUEP). Bremerton's conservation program is
described in Section 3.

I. Projected water use was estimated from data provided in the projects' sub-area plan.
2. An Equivalent Residential Unit (ERU) ~ 200 gallons/day ADD for Bremerton's system
3. NASCAR development as of 12/06 is extremely preliminary. Water use is estimated to be 1,500gpm peak domestic only 3 days per year with occasional lower
demands the rest of the year and 3.000 gpm for 3 hours fire flow. Additional storage not currently identified in the CIP would be required for the track.
2.5.1 Forecast withoutConservation
Average day system demands were forecasted in Tables 2-4, 2-5 and 2-6, assuming a
continuation of the existing residential per capita demand and using projections provided
by PSNS and for planned commerciallindustrial development. Annual average demand
projections were based on the following:
Planning Background Information
2-25
2005 City of Bremerton Water System Plan
. Residential demands for single-family housing were calculated by increasing the 2004
single-family residential demand of 2.63 MGD by the same percentage as the
projected population increases. Additional demands were reduced by 5 percent to
account for implementation of federally-mandated, reduced flow plumbing fixtures in
new construction.
. Multi-family units forecasted demands were calculated the same way as single-family
units.
. Non-residential demands for commerciallindustrial development were increased by
the same percent as the forecasted population growth. The increased demands of
proposed large developments identified in Table 2-10 were added to the forecasted
commerciallindustrial demands beginning in the years they are anticipated to be built.
. Irrigation demands were calculated to increase at the same rate as population growth.
. Without conservation, Navy industrial use would remain constant, and residential use
would increase with population increases.
. Non-revenue water was assumed to stay stable at the current 6-year average of 6
percent.
. Rocky Point Water District demands are expected to increase with the forecasted
increase in the population for that area.
. City of Port Orchard is forecasted to use the maximum amount of water allowed in
the interlocal agreement.
2.5.2 Forecast with Conservation
Bremerton has emphasized water conservation since 1992. In the 1999 WSP, the City
anticipated making the conservation achievements shown in Table 2-11 between 1999
and 2004.
A separate "with conservation" average day demand forecast is included in Table 2-4 and
was calculated taking projected conservation reductions into account as follows:
. Single-family residential - Reach 5 percent of our accounts (approximately 700
units) each year for the next 10 years and they reduce by an additional 10 percent.
This includes reductions in both indoor and outdoor use.
e Multi-family residential -:- Reach 5 percent of the units (approximately 300 units)
each year for the next 10 years and they reduce water use by 5 percent. Opportunities
for water use reduction are more limited with multi-family dwellers.
. Commercial- Reach 5 percent of accounts (approximately 130 units) each year and
they reduce water use by 5 percent This includes only indoor use.
e Irrigation - Reach 5 percent of the irrigation accounts (approximately 10 accounts)
each year and they reduce use by 5 percent. In 2012 begin using reclaimed water at
Pendergast Park.

3.1 Introduction
The purpose of this section is to ensure that several options for water sources are considered to
meet projected demands. These options include:
· Optimization of existing sources,
· Enhanced conservation measures,
· Water right changes,
· Interties,
· Aquifer Storage and Recovery (ASR),
· Use of reclaimed, non-potable water,
· Treatment, where applicable, to permit use of water sources requiring more comprehensive
treatment to meet current water quality regulations, and
· Applications for new sources.
3.2 Water Sources
Surface water and groundwater production is presented in Table 2-3 for the period 1985 to 2004.
Surface water is obtained from the Union River system, while groundwater is drawn from local
production wells. Average contributions from surface water and groundwater over the last 20
years are 1,776 and 1,200 million gallons per year or a distribution of 60 percent and 40 percent,
respectively.
Substantial increases in groundwater production occurred in 1992 and 1993, and in 2001 through
2004 due to decreased surface water availability and drought conditions. Table 2-3 also indicates
a falling trend in total production since 2001 when the Water Shortage Contingency Plan was
activated in response to that year's drought.
Note that 1994 through 1999 had significantly higher than average precipitation, which can cause
lower demands from reduced outdoor use. Maximum Day Demand, which reached its highest
levels from 1988 to 1991, has reduced since and stabilized to about 15 MOD.
3.2.1 Surface Water Sources
The Union River surface water annual firm yield estimate is 2,020 million gallons, which
includes an estimate of the West Branch contribution at 250 million gallons and
minimum downstream flows. This firm yield estimate is close to current average City
surface water usage but less than actual average total diversions, which include diversions

2005 City of Bremerton Water Supply Plan
to Twin Lakes. This diversion is used to recharge the Twin Lakes Aquifer and has
averaged approximately 350 million gallons per year. The firm yield analysis indicates
that reliable surface water contributions to the City's water supply system are close to
being maximized under the existing production procedures.
3.2.2 Groundwater Sources
Groundwater supplies are obtained from 13 active production wells in the Garst Creek
Basin, Anderson Creek Basin, and the Manette Peninsula. These wells are described in
Tables 3-1and 3-2 and in the Kitsap County Initial Basin Assessment.
Several studies on the City's groundwater systems have been conducted and are described
below.
Kitsap County Groundwater Management Plan (GWMP) - The GWMP was prepared
in accordance with Chapter 173-1 00 WAC, Groundwater Management Areas and
Programs, which led to designating Kitsap County as a Groundwater Management Area
(GWMA) in October 1986. An Interlocal Agreement between the Kitsap Public Utility
District and the Kitsap County Board of Commissioners in December 1986 established
both entities as co-lead agencies for the evaluation and preparation of the GWMP. The
GWMP document is presented in four volumes. Volume I is an assembly and analysis of
groundwater related data and includes estimates of groundwater availability, use, and
projected demand.
Volume II provides technical supporting data and additional information developed for
each of the study's five individual subareas. Volume III covers a variety of management
issues and policies deemed appropriate by the Groundwater Advisory Committee to
provide a comprehensive management strategy for groundwater resources throughout
Kitsap County. Volume IV provides supporting and additional information, including the
Kitsap County Initial Basin Assessment and issue papers developed in the process.

Wellhead Protection Plan - The Washington Department of Health adopted a Wellhead
Protection Program in July 1994 requiring all suppliers of public drinking water to
implement a wellhead protection plan. Each drinking water purveyor must define that
portion of the aquifer providing groundwater to a production well. The overlying land is
designated into 1-, 5-, and 10-year time-of-travel wellhead protection areas. Within these
protection areas, a land use inventory must be conducted every two years to identify
activities with the potential to contaminate groundwater, and the sites within the
protection areas are notified and sent pollution prevention materials. The City's most
recent update to the Wellhead Protection Plan was in 1996 and was previously submitted
to DOH.
Corst Creek Basin Study - An analysis of the Gorst Creek Basin groundwater supplies
was conducted in 1996 describing basin hydrogeology and hydrology, developing a
computer model, and evaluating various management strategies. Conclusions from this
study included:
The Gorst Creek Instream Flow Requirements (IFR) were set too high, since the
existing IFR could not be met under natural conditions.
Significant quantities of groundwater were discharging to Sinclair Inlet from the
Lower Garst Valley and were considered to be a potential resource without hydraulic
continuity constraints.
Most of the water diverted to Twin Lakes is lost to seepage to the Union River and
Garst Creek and partially captured by Wells 18 and 20.
Anderson Creek Well Field Evaluation ..:...An aquifer test was performed to confirm
safe yield and to maximize existing inactive wells through a replacement program in this
area.

3.3 Enhanced Conservation Measures
Water demand management through efficiency and conservation can be a cost-effective tool for
meeting water needs for population growth while saving the Utility capital costs and improving
customer relations. The City has placed an increasing emphasis on water conservation efforts
since 1992. Evaluation of water use by equivalent residential unit (Table 2-7) indicates a steady
reduction in water use since 1999. Total water use has remained steady for the past 10 years.
Customers responded enthusiastically to the 2001 drought conservation message and reduced
water use that summer by 18 percent, well in excess of the 10 percent voluntary reduction the
City requested.
Non-revenue water is defined as the difference between metered source water and metered water
sales. Non-revenue water can be authorized uses such as for flushing, fire fighting, and hydrant
flow testing or unauthorized uses such as leaks and theft. Generally, systems having less than 10
percent non-revenue water are being maintained properly. Since 1999, Bremerton's non-revenue
water has averaged 5.7 percent, which indicates that water loss is not a problem (Figure 2-10).
Bremerton has implemented enhanced conservation measures, defined as measures above and
beyond those required for a medium-sized water system. In accordance with the recommended
water conservation program contained in the DOH 1994 publication, "Conservation Planning
Requirements," the City is required to implement the measures for a medium system. Table 3-3
identifies the measures required for medium systems, as well as those implemented by the City.

2005 City of Bremerton Water Supply Plan
Table 3-3 shows that despite classification as a "medium" system, the City has implemented
most of the requirements of a large system. In addition to these measures, demand has been
reduced by the 1992 Energy Policy Act, which requires efficient plumbing features in new
construction. These indoor water-efficient devices, such as low flow toilets, faucets, and
showerheads, save an estimated 35 percent of indoor water use (Vickers, 2001). The overall
effectiveness of all these measures is confirmed by trends already noted in Table 2-11.
In 2003, the Washington State Legislature passed the Municipal Water Supply - Water Use
Efficiency Requirements Act. The Department of Health is expected to adopt water use
efficiency regulations in 2006. Under the new regulations, the City of Bremerton will be required
to implement the measures for a large system (over 10,000 connections) and prepare Water Use
Efficiency Plans (\VUEP). The WUEP for the City of Bremerton is currently "interim" to
meeting the requirements of the 2005 Water System Plan schedule and contains many elements
of the new regulation but cannot be completed until the requirements of the new regulations are
finalized.
The City of Bremerton values the continued high quality and usually ample supply of its water-
resources. Customer education about water quantity and quality creates awareness, which can
result in improved water use habits. Water use efficiency can be viewed as a resource, an
alternative to developing new water supplies to meet new water demands. The current objectives
of the City of Bremerton WUEP are:
· Maintain use per ERU at or below 200 gallons per day per single-family residence.
· Keep Maximum Day Demand less than twice the Annual Average Day Demand.
· Meter every source.
· Meter all demands as practicable and provide an estimate for demands that cannot be metered
(such as for flushing and firefighting).
· Maintain the water system to prevent leaks, promptly repair all leaks that occur, and maintain
the difference between volume of water produced and metered water used below 10 percent.
· Educate customers about their water sources and basic water supply principles.
e Work with the Navy, Bremerton's largest point water user, to enhance its water efficiency.
· Encourage a conservation ethic.
· Increase customer awareness of water-use habits and the value of water.
· Continue to reduce system wide per-capita water consumption.
· Improve system reliability.
· Protect environmental resources.
· Ensure water use efficiency prior to using new sources of supply.

3-6
2005 City of Bremerton Water Supply Plan
Under the new requirements, Bremerton will have to implement a public process for City
Council to set water efficiency goals considering:
· Historic water use efficiency performance,
· Historic water use efficiency investment,
Q Customer base demographics,
· Regional climate variations,
· Forecasted demand characteristics,
· Water supply characteristics,
· System financial viability,
· System reliability, and
· Affordability of water rates.
Implementation of water efficiency objectives has the potential for water savings on both a daily
demand basis and a peak demand basis, thereby delaying the need to develop costly new
resources and avoid capital costs. Water use efficiency programs will also be required if a
system will be requesting additional water rights or applying for State Revolving Fund loans.
Table 3.4 identifies the measures required for both medium and large public water systems under
the new water efficiency requirements. In addition to these measures; demand has also been
reduced by the 1992 Energy Policy Act, which requires efficient plumbing features in new
construction.

3.4 Water Rights Evaluation
The status of the City's water rights was reviewed and each right's characteristics and limitations
determined, so the City can fully utilize its water resources. An inventory of all Bremerton water
rights claims, certificates, and applications is listed in Table 3-5. The ability of the water rights to
meet future projected demands is presented in Table 3-6. This table contains several sources that
appear as water rights surplus, although they are currently not in use and have the following
explanations:
· Charleston Creek - This claim is for a historically-used source, which is no longer used.
· Anderson Creek - The City maintains this water right as an emergency source.
· Gorst Creek - The City maintains this water right as an emergency source.
Bremerton does not currently receive any of its water from interties with other systems. An
intertie exists between Bremerton's main system and the West 517 Zone. The City of Bremerton
holds water rights certificates and claims for both surface water and groundwater. With
Bremerton's dual sources, both current and forecasted 2024 average day demands and maximum
day demands can be met, as indicated in Table 3-5. These dual sources are operated
conjunctively to maximize resource efficiency. Generally, surface supplies are emphasized
during the high precipitation periods in the winter and spring, and groundwater sources are used
in addition to the surface water in the summerand fall. Since Bremerton's surface water supply is
unfiltered, the City relies on groundwater during times when storms cause the turbidity to
increase on the surface supplies above desired levels. It is essential that the City maintains
adequate groundwater supplies to maintain system reliability.
Because Bremerton utilizes an unfiltered surface source for 60 percent of its supplies, the City
needs to be able to meet average day demands with only well sources during the times the surface
supply is unavailable due to high turbidity or during severe drought conditions. Because severe
drought conditions are likely to correspond to maximum day demand periods, the City should
maintain capacity in its groundwater supply to meet all of the system demands. The City has the
following pending water right actions:
· Change of purpose and place of use for five Domsea wells to the Gorst Production Well
(Well 22) (1,200 gpm total, 233.5 gpm for consumptive use, 966.5 non-consumptive)
· Change of amount for Well 9 to 1,000 gpm (1,600 AFY)
· New application for WeIl21 (500 gpm, 800 AFY)

2005 Bremerton Water System Plan
Evaluation of current and future demands, Figures 3-1 and 3-2, shows the analysis of average day
demands and maximum day demands compared to existing water rights, accessible rights and
groundwater only. The projected 2024 average day demand is 14.0 MGD. Figure 3-1 shows that
while the City's water rights claims and certificates total an average day demand of 36.6 million
gallons per day (MGD), the firm yield of the surface supply system is only 5.6 MGD. Therefore,
the currently accessible portion of water rights (Firm Yield) plus groundwater rights totals 16.9
MGD. However, if the City had to rely on its groundwater supply only, a shortfall in installed
capacity and water rights would exist by the year 2016.

The projected maximum day demand (MDD) for the year 2024 is 27.9 MGD. Figure 3-2 shows
the existing water rights for the City total 57.3 MGD; however, removing the emergency supplies
leaves 40 MGD of available rights. Since the surface water source is unfiltered and future
climate change may affect the groundwater supply, it is important to consider the ability of the
system to meet demands from its groundwater supplies bnly. The figure shows that the existing
maximum day demands cannot. be met by the existing groundwater instantaneous rights or the
installed capacity. To meet future demands from groundwater only, additional groundwater
rights (Qa and Qi) and installed capacity of 4.2 MGD Qa (4,688 acre-feet Qa), 13.9 MGD Qi,
and 16.4 MGD of installed capacity are needed. Table 3.7 provides a summary of the analysis.

2005 Bremerton Water System Plan
The City filed four applications in 1954/57 for withdrawal and storage from the Hamma Hamma
river system. This surface source was evaluated in past reports and identified as a potential
regional supply in the Kitsap County CWSP. Ecology contacted the City in 1998 regarding
these applications, since the Hillis legal decision required the State to act on applications in order
of date. The City responded that any decision regarding this application should be held off
pending resolution of important water rights and ESA questions. In April 1999, Ecology denied
these applications, and Bremerton did not appea1.
In recent years, it has become increasingly difficult to obtain new water rights from Ecology.
This is due to a combination of factors, including inadequate staffing at Ecology, increased
attention to protection of instream flows, inadequate data or consensus on the relationship
between groundwater withdrawals and stream flows, and implementation of WRIA-based state-
funded watershed plans. Some improvement has occurred in recent years, since Ecology is now
processing change applications. However, no definitive solution to this problem seems to exist.
Ecology anticipated collaborative watershed plans would help determine whether new rights can
be issued in each basin. A watershed planning process was funded for WRIA 15, the basin
comprising the Kitsap Peninsula and including Bremerton's sources of supply. However, after
five years of work and development of a draft plan, the plan was rejected due to the veto of the
Sqauxin Island Tribe, an initiating government. This action halted the watershed process, and
WRIA 15 will not be eligible for further watershed implementation funds.
Utilizing changes to existing water rights can be an alternative to making application for and
securing additional new water rights. Several advantages to this include the better potential for
approval of an application for change than a new application and obtaining water rights with
earlier priority dates than for a new application. The following approaches are recommended for
securing needed new water sources:
· Continue to pursue Domsea Wells change application for the new well drilled in 1993.
. Continue to pursue application for Well 9.
· Continue to pursue application on Well 21 (Emergency Water Rights were received in 2001).
. The City is currently maximizing surface water sources and new sources will likely be
groundwater. A letter has been sent to PUD #1 regarding drilling a test well to potentially
serve an area of planned industrial growth in the City' s West 517 Zone.
. Apply for a replacement well for Well 4 for 865 gpm and 806 aflyr to maximize these claims.
. Apply for anew groundwater permit for supplemental water rights of 890 gpm and 867 aflyr
to use unused existing groundwater certificate capacity.
. Apply for a new wellfie1d permitwith a capacity of 3,500 gpm (for 20 year demand) and at
least 5,000 aflyr to ensure reliability in the water system in case of drought or other
conditions that would render the surface water supply unavailable.
. Alternately, if the hydrogeological study shows potential for aquifer storage and recharge
(ASR), apply for a storage permit for groundwater.
Sources of Supply
3-20
2005 Bremerton Water System Plan
· Conduct hydrogeological investigations to determine the potential impact on surface water
supplies for the wellfield operation.
All of the above options for water right changes will be fully considered by the City as elements
in developing strategies to meet future demand projections.
3.5 !nterties
As defined within RCW 90.03.383, the City has one emergency and five non-emergency interties
as listed below. The emergency intertie to North Perry Water District was installed in the early
1980s and has never been used. The non-emergency interties are:
. City of Port Orchard
. Puget Sound Naval Shipyard
. Jackson Park Naval Housing
. Rocky Point Water District
· City of Bremerton West 517 Zone Water System (identified as a separate water system by
DOH)
Table 3-8 lists pertinent information on the interties. The City can provide water to each of the
areas listed in Table 3-8. Except for Port Orchard and North Perry Avenue Water District, these
areas do not have their own sources of potable water that could serve the City. Port Orchard and
North Perry do not have excess supply capacity that could supplement the City's water sources
on a sustained basis. Therefore, these interties cannot assist in meeting future Bremerton
demands.

3.6 Aquifer Recharge
Aquifer recharge is one potential option for additional future sources of water supply for
municipalities. In most instances, aquifer recharge consists of introducing groundwater or
surface water into a groundwater aquifer, storing the water in the aquifer for a period, and then
withdrawing the water through wells later.
The City has been following a procedure incorporating the concepts of aquifer recharge in which
surface water is diverted from the Union River into Twin Lakes. Studies show that water
introduced into Twin Lakes percolates into and recharges the Twin Lakes Aquifer and then flows
laterally into both the Union River and Gorst Creek Basins. The City then recaptures a portion of
this aquifer recharge through City wells. All required water rights authorizations are in place.
The State of Washington recently formalized a procedure for dealing with this practice. Aquifer
recharge programs have been undertaken by a few. municipalities, such as Seattle at their
HighIine Wellfield, Yakima, and Walla Walla. Bremerton has plans to pursue this option, which
may allow more use of the Gorst area aquifers.
3.7 Water Reuse
The City owns and operates a secondary Wastewater treatment plant (WWTP) with an average
flow of about 6.2 MGD, which could potentially be reclaimed after further filtration. Water reuse
is the beneficial use of reciaimed wastewater treatment plant effluent in compliance with
Washington Departments of Ecology and Health regulations.
Bremerton's WWTP currently uses reclaimed secondary wastewater effluent for process and
odor control and to irrigate inside the WWTP grounds and at a neighboring business.
Approximately 150 gpm are used for in-plant uses, and an additional 120 gpm are used in the
summer months for an annual total of 88 MG/year. A "Water Reuse Feasibility Study"
completed in 1998 identified the potential demands for and costs to provide additional reclaimed
water to potential users in the Bremerton area. Bremerton's wastewater has higher than average
saltwater from collection system infiltration and Puget Sound Naval Shipyard inflow making
reuse possibilities challenging.
A 2005 County-wide reuse study indicated that Bremerton had the least potential for large-scale
reuse and recommended grant funding be focused at other locations with more feasible reuse
opportunities. The City is currently evaluating the next step to take in reuse.
3.8 Treatment
DOH recommends that purVeyors experiencing reduction or loss of water sources due to water
quality problems consider treatment to restore the source. This approach does not apply to the
City's water system, since its main sources are not impaired by water quality problems.
However, both Anderson Creek and Gorst Creek were historically used by the City and are
maintained as emergency supplies. To be used long term, both sources would need to be treated
in compliance with the SWTR.

2005 Bremerton Water System Plan
The Long Term 2 Enhanced Surface Water Treatment Rule was promulgated in December 2005.
This new rule will require the City of Bremerton to conduct further Cryptosporidium monitoring
and to provide a second disinfectant in addition to chlorine. Section 4 provides further analysis of
the impacts of this new federal rule on Bremerton. Should reliability or quality of Bremerton's
surface supplies become an issue, then filtration would be an option to consider.

Increasing greenhouse gases in the atmosphere lead to an increase in the earth's air temperature.
Evaluation of long-term temperature records for the Pacific Northwest shows substantial
warming during the 20th century. A considerable body of research leads to the conclusion that
the increase in globally-averaged temperature in the past 30-50 years is largely due to the rapidly
rising greenhouse gases. Concentrations of greenhouse gases are much higher than they have
been at any time since the rise of civilization 10,000 years ago. The climate, land surface,
glaciers, and oceans are responding to these changes. Anticipating future directions of change is
crucial in order to minimize the impacts of future change on water resource management.
Current global and regional climate change models predict the following:
· Climate change is a reality - the future will be warmer but uncertainty is unavoidable.
· Climatological history is not a reliable guide to predicting the future.
· Average temperatures are increasing, and the Puget Sound region warmed at a rate faster than
the global average.
· Sea levels in the Puget Sound will rise 4 to 35 inches in the next century due to climate

· Less certainty exists about how climate change will affect precipitation. However, models
indicate that although annual average precipitation could stay about the same, winter
precipitation will increase slightly, and summer precipitation will decrease slightly.
. Increases in intensity of winter rains are expected.
. Snow pack is decreasing. .
The main messages for water system managers from recent climate change research are:
. Preparing for climate change is a high-stakes exercise in risk management.
. Develop a climate change "insurance portfolio."
· Integrate climate change projections in all appropriate City planning documents.
· Summer drought is the Northwest's biggest vulnerability in a climate change scenario.
· Expect surprises, enhance the water system's ability to respond to change, and ensure
flexibility.

3.10 Water System Reliability Analysis
Water System reliability is the degree to which an adequate quantity of water canbe provided at
acceptable service standards. The areas of reliability are source reliability for water quantity and
quality, water right adequacy, customer service, and facility reliability. The actions that
Bremerton takes to increase reliability are described below.
3.10.1 Source Reliability - Water Quantity
· Bremerton's dual-source system of surface Water and groundwater provides system
reliability, flexibility, and redundancy. In the event that surface sources are
unavailable due to turbidity events or water shortage, then ADD can be met with
groundwater sources only. hl the event that an individual groundwater source is
unavailable, then the system is flexible enough to meet demands with other sources.
Bremerton's plan is to increase groundwater supplies to increase reliability.
Sources of Supply
3-24
2005 Bremerton Water System Plan
· In the event of a severe water shortage, the City has several emergency sources
available, including Anderson Creek and Gorst Creek. Bremerton has a Water
Shortage Contingency Plan that was successfully implemented during the 2001
drought. Bremerton actively educates customers on storing emergency water
supplies. A countywide Emergency Water Plan is in progress.
· Bremerton has two drilled wells awaiting water lights approval for use III an
emergency.
· Hydraulic studies such as the Gorst Creek Basin Study and the Kitsap County
Groundwater Management Plan give valuable information on water quantities of the
aquifers utilized by the City.
· Bremerton completed a Water Reuse Feasibility Study to identify possible uses for
reclaimed water. Some reuse applications are currently in place at the WWTP.
· Well levels for all City groundwater sources are monitored to ensure aquifers are not
being depleted. These data are entered into a computerized data base to easily
determine trends.
· A firm yield analysis of the Union River system was performed in 1999 to provide
information to maximize, yet not over-use, the City's surface water supplies.
· Bremerton has an active water conservation program described in Section 3.3 that
goes beyond the minimum requirements.
3.10.2 Source Reliability - Water Quality

· Disinfection is also ensured throughout the distribution system through maintenance
of a free chlorine residual. Weekly coliform monitoring conducted in accordance
with the City's Coliform Monitoring Pl3-Tl provides feedback on disinfection
adequacy.
· All of the City's water quality data are tracked in a computer data base so trends and
changes can be easily discerned.
· Bremerton has an effective cross connection control program to prevent
contamination of the water in the distribution system.
· The City's annual flushing program helps protect distribution system water quality.
· Reservoirs are regularly inspected to prevent entry of contaminants.
· The City's corrosion control treatment facility ensures that corrosion of household
plumbing does not occur.
· Computerized tracking of customer water quality complaints assists in addressing
distribution system issues.
3.10.3 Water Right Adequacy
The City's water rights were reviewed and are presented in Section 3.4. The City
currently has adequate water rights with its combined sources to meet projected demands
through the planning period.
3.10.4 Facility Reliability
· Section 8 describes the system analysis that was conducted to ensure adequate fire
flows and to evaluate water system improvements. The City's Capital Improvement
Program (CIP) outlines how improvements will be addressed.
· Section 6 describes backup systems and redundancy criteria used by Bremerton for
design of the system.
· Bremerton has implemented most of the recommended seismic upgrades identified in
the 1997 Earthquake Vulnerability Assessment, including bracing the Casad Dam
intake tower, improving reservoir foundation stability, and installing several seismic
valves.
· All water operators and most maintenance personnel are state-certified in water
distribution system operation. Bremerton has an active program of training in safety,
facility operation, and regulations. This ensures responsible operation and
maintenance of facilities.

2005 Bremerton Water System Plan
· Regular and preventive maintenance of system components, including reservoirs,
wells, pump stations, valves, and fire hydrants, is tracked by a computerized
maintenance management program.
· The City evaluated water system facility vulnerability to seismic events in the Water
System Earthquake Vulnerability Assessment (1997). Recommended actions are
mostly complete and scheduled in the City's CIP.
· Casad Dam and Reservoir 4 are impoundments regulated by the Department of
Ecology Dam Safety Section and have written Operation and Maintenance Programs
and Dam Safety Plans implemented by the City.
· The chlorine facility at McKenna Falls is in compliance with its Risk Management
Plan, which is implemented by the City.
· All major water system facilities are visited at least daily by state-certified water
operations personnel.

set-points are exceeded or if power outages or communication failures occur. This
telemetry system is currently being converted from telephone to radio to increase
reliabili ty.
-The City has an Emergency Response Plan and provides training and practice drills
for Water Utility personnel.
3.10.5 Customer Service Reliability
- Water quality and conservation information IS posted on the City's website
(www.ci.bremerton.wa.us)to communicate the value of water.
- A consumer confidence report is sent in the customer bills each spring.
· Bremerton has a Customer Response number (473-5920) to call to dispatch a
Customer Response Technician for water service issues within two hours.
· Customer calls are logged into a data base.
· Customers are notified about planned flushing activities in the newspaper and on
neighborhood signs. A water quality and flushing hot line (473-5490) is also
available.
- Customers are notified of planned water service disruptions by door hangers.
· Customer water information is also disseminated at city facilities and local libraries
and at special events.

Water Quality Review and Regulatory
Compliance
4.1 Objective and Approach
This chapter provides a review of current state and federal drinking water regulations pursuant to
the Safe Drinking Water Act (SDW A) and an assessment of the City's compliance status based
on water quality data and information collected for the period 2000 to 2005. This chapter also
summarizes applicable anticipated regulations and their potential implications to the City. The
approach used to achieve these objectives includes the following:
. Overview of the City's sources of supply
. Description of current state and federal drinking water regulations
. Description of upcoming reguiations that could impact the City's system
. Review of existing monitoring plans, practices, and water quality data
. Assessment of existing compliance status and potential future compliance issues
. Proposed action plan to ensure continued compliance
4.2 Description of State and Federal Regulatory Framework
The City provides 100 percent of its own drinking water and supplies water to an additional four
contract customers. The City is responsible for monitoring and compliance with all SDW A and
state regulations pertaining to source water and distribution system water quality that are
applicable to unfiltered surface water and groundwater systems.
4.2.1 Safe Drinking Water Act
The federal regulatory framework directing water quality is the SDW A of 1974 and its
1986 and 1996 amendments. The SDW A and amendments, as administered by the EP A,
significantly impact the operation and monitoring of the Bremerton water systems.
The regulatory impacts to Bremerton include requirements for filtration avoidance,
disinfection, bacteriological quality, disinfection by-products, and source and system
water quality monitoring.
A '" '" \AI__L:__.l.__ ^ ~__:_:_...._-:...:..._ ,,_..:J_
"'t."-."- VVd~IIIIIHlUIII"\UIIIIIII~lIdllVe ....uue
The State law that incorporates the SDW A and its amendments is Chapter 246-290 of the
Washington Administrative Code (WAC 246-290). DOH is the primacy agency
responsible for ensuring state drinking water laws are implemented and enforced. Both
the Main System and the West 517 Zone are classified as Group A public water systems.
However, according to WAC 246-290-020, the main system is classified as a community

water system (CWS), while the West 517 Zone is classified as a non-transient, non-
community (NTNC) water system (with a service population of about 400). The City is
required to meet drinking water quality regulations and conform to sampling and
reporting requirements for these systems.
4.3 System and Supply Overview
While Bremerton is responsible for meeting treatment, water quality, and monitoring regulations
at its points of delivery, each of the four separate contract systems served is required to ensure
compliance with water quality and monitoring requirements within its distribution systems.
The City utilizes both surface and groundwater sources to meet supply needs. On a system-wide
basis, about 60 percent of annual production is derived from the Union River surface source,
with the remaining 40 percent obtained from groundwater production wells located throughout
the service area.
The City operates the Union River supply under the filtration avoidance criteria of the Surface
Water Treatment Rule (SWTR), which requires watershed protection and control to maintain
high quality source water. The surface supply is treated with chlorine at the McKenna Falls
Intake Facility to meet the SWTR disinfection requirements for Giardia lamblia and viruses.
Caustic soda is applied upstream of Reservoir 4 to adjust pH for distribution system corrosion
control. The Union River surface water firm yield estimate is 2,020 million gallons per year. This
supply directly feeds the West 256 and East 240 zones.
The groundwater production wells are located throughout the service area and described in
Section 3 and Table 4-1. Each well, with the exception of Well 19, is equipped with chlorination
facilities (either gas or hypochlorite) for disinfection. The City drilled two other wells that have
not yet been put into production, as they are currently pending source and water right approval.
The West 517 Zone is supplied by three production wells: 15, 18R, and 19. This zone also has
an intertie with the surface water transmission main. Water can move through the intertie in
either direction (pumping is required to move water to the West 517 Zone but can be gravity fed
into the West 256 Zone).
Table 4-1 provides a reference summary of the City's sources of supply and their associated
identification numbers, including City Source ID, DOH Source Number, and DOH Plant ID
number. The DOH Plant ID numbers were created in 2002 to designate unique entry points to
the system for monitoring purposes.

As part of the Phase II Rule, systems with a significant amount of asbestos-cement (AC)
pipe must conduct periodic asbestos monitoring in the distribution system. In Washington
State, DOH historically required systems containing more than 10 percent AC pipe to
comply with the monitoring requirement. These systems must collect one sample in the
distribution system at a tap served by AC pipe under conditions where asbestos
contamination is most likely to occur.
Bremerton Status
Prior to 2003, the City conducted its monitoring for inorganic and organic compounds on
individual sources. However, beginning in 2003, the monitoring locations were changed
to designated entry points in the distribution system to be consistent with updated state
regulations. For the main system, this includes the five entry point locations identified as

2005 City of Bremerton Water System Plan
Main System:
The City performs monitoring of primary and secondary IOCs and physical parameters
according to its Main System Monitoring Plan for Inorganic Chemicals (last updated
March 2005). The City currently monitors entry point T-l (which includes the Union
River surface supply and Wells 17 and 20) annually for IOCs, physical parameters, nitrite,
and nitrate. Sampling was most recently completed in May 2005. The City currently
monitors entry points T-2 through T-5 (all of which include entirely groundwater
supplies) once each three-year compliance period for IOCs, physical parameters, and
nitrite and annually for nitrate. IOC monitoring for the 2005-2007 compliance cycle for
entry points T-2, T-3 and T-5 is scheduled for 2007. A review of monitoring data
collected since 1999 shows that the City has maintained compliance with all primary
MCLs at each of these entry points. With regard to secondary inorganics and physical
parameters, periodic exceedance of secondary MCLs for manganese (0.05 mg/1) and color
(15 color units) has occurred. However, compliance with secondary MCLs is voluntary.
The main system contains nearly 130,000 feet ofAC pipe, accounting for approximately
8.5 percent of the pipe inventory in this system. Although monitoring for asbestos was
not required, the City sampled the main system in 1995 and 2004. All results were below
the detection limit.
The City performs monitoring of VOCs and SOCs according to its Main System
Monitoring Plan for Organic Chemicals. The City is currently on a reduced monitoring
schedule for VOCs, with one round of sampling required at each entry point each three-
year compliance period. Sampling was most recently completed in July 2005 at each of
the five entry points. All VOC results since 2000 have been below the detection limit.
With regard to SOCs, the City has been eligible for waivers for its wells and Union River
supply since 1993 due to their low susceptibility rating. Waivers were obtained for the
periods 1993-1995, 1996-1998, and 1999-2001. The City performed entry point SOC
monitoring in 2002 and 2003 as part of the Unregulated Contaminants Monitoring Rule
(UCMR), and all results were below the detection limit. The City reapplied for and was
granted SOC waivers for the 2005-2007 monitoring period.
West 517 Zone
The City performs monitoring of primary and secondary IOCs and physical parameters
according to its West 517 Zone Monitoring Plan for Inorganic Chemicals. The City
currently monitors each well (15, 18R, and 19) once each three-yearcompEance period
for IOCs, physical parameters, and nitrite. The most recent round of sampling was
performed in March 2004. A review of monitoring data collected since 2000 shows that
the City has maintained compliance with all primary and secondary MCLs at each well.
The City monitors each well annually for nitrate. Since 2000, the maximum nitrate
observation was 1.9 mg/L as N observed at Weii 19.

2005 City of Bremerton Water System Plan
The West 517 Zone contains roughly 36,000 feet of AC pipe, accounting for
approximately 60 percent of the pipe inventory in this system. According to DOH
requirements, the City performs asbestos monitoring in the West 517 distribution system
during the first three-year period of each 9-year compliance cycle. The most recent
sample was collected in August 2004, and no asbestos was detected. The next 9-year
cycle begins January 2011.
The City performs monitoring of VOCs and SOCs according to its West 5 J 7 Zone
Monitoring Plan for Organic Chemicals. The City is currently on a reduced monitoring
schedule for VOCs, with one round of sampling required each three-year compliance
period. Sampling was most recently completed in July 2005. All results since 2000 have
been below the detection limit. With regard to SOCs, the City has been eligible for SOC
waivers for its wells since 1993 due to their low susceptibility rating. Waivers were
obtained for the periods 1993-1995, 1996'-1998, and 1999-2001 and 2002-2004. The City
reapplied for and was granted SOC waivers for all sources for the 2005-2007 monitoring
period.
4.4.2 Arsenic Rule
Regulatory Elements
The original arsenic MCL of 0.05 mg/L was established as part of the 1975 National
Interim Primary Drinking Water Regulations. After years of additional health effects
research and cost/benefit analysis, the EP A published the final Arsenic Rule in January
2001, with an effective date of January 2006. The Arsenic Rule revises the arsenic MCL
downward to 0.010 mg/L and identifies several best available treatment technologies for
compliance. Compliance with the new MCL is based on the running annual average of
monitoring results at each entry point to the distribution system. The rule makes arsenic
monitoring requirements consistent with monitoring for other IOCs regulated under the
Phase IIIV standardized monitoring framework. However, if arsenic is detected above the
MCL in any individual sample, the system must increase the frequency of monitoring at
that sampling point to quarterly.
Bremerton Status
A review of historical IOC monitoring data indicates that all existing City water sources
(both in the main system and the West 517 Zone) have arsenic concentrations less than
half of the new MCL. Because of this, it is expected that the new arsenic rule will not
impact the City.
4.4.3 Radionuclides Rule
Regulatory Elements
1 ne original Radionuclloes Rule went into effect in 1978. The rule was reviseo III
December 2000, with an effective date of 2003. The revised rule applies only to CWSs,
and according to WAC 246-290-300.10, DOH has adopted the federal rule without
Water Quality Review and Regulatory Compliance
4-6
2005 City of Bremerton Water System Plan
additional regulation of NTNC water systems. Therefore, the rule has no impact on the
West 517 system.
The revised rule includes MCLs for radium-226 and radium-228, referred to as combined
radium (5 pCi/L), adjusted gross alpha emitters (15 pCi/L), beta and photon emitters
(4 mremlyear), and uranium (30/lg/L). Under this rule, monitoring for radionuclides
must be conducted at each entry point to the distribution system.
The revised rule also allows for eliminating the analysis of radium-226 and uranium if the
gross alpha results are less than or equal to 5 and 15 pCi/L, respectively. The required
monitoring frequency will be determined by DOH based on contaminant levels.
Bremerton Status
The City has a Monitoring Plan for Radionuclides. The City collected gross alpha
samples for all main system entry points except T-4 (Well 9) during 2003 and
grandfathered these datato reduce new monitoring requirements (note that Well 14 was
considered part of entry point T - 3 during the 2003 monitoring but has since been
designated as T-5). Since all gross alpha results were below 5 pC ilL, the City is not
required to conduct radium-226 or uranium sampling at these sources. Testing for entry
point T -4 (Well 9) has resumed now that the well is back in service.
The City was also required to test for radium-228. Although federal regulations require
quarterly radium-228 sampling, DOH required that the City complete two sampling
events separated by approximately six months. The City is awaiting these results. DOH
will direct water systems regarding future radiological monitoring requirements.
Bremerton has not been designated vulnerable to beta particle aJld photon emitter
radioactivity and has not been required to monitor for these parameters.
4.4.4 Lead and Copper Rule
Regulatory Elements
Lead and copper are metals that may be found in household plumbing materials and water
service lines. Lead ingestion has been linked to several adverse health impacts, including
impaired physical and mental development in infants and children. Copper can cause
aesthetic issues in addition to acute and chronic health impacts. The Lead and Copper
Rule (LCR) establishes monitoring requirements, action levels, and compliance
requirements to control the levels of these constituents in drinking water. Under the LCR,
water systems are required to conduct monitoring at customers ' taps to determine if more
than 10 percent of homes meeting certain criteria exceed the lead and copper action levels
of 0.015 mg/L and 1.3 mg/L, respectively. The LCR specifies required actions for
systems exceeding the 90th percentile levels. In January 2000, EP A published minor
revisions to the LCR. The purpose of the Lead and Copper Rule Minor Revisions
(LCRMR) was to eliminate unnecessary requirements, reduce monitoring and reporting
burdens, and promote consistent national implementation.

2005 City of Bremerton Water System Plan
Bremerton Status
Main System
The City has remained in compliance with the LCR action levels since corrosion control
facilities were installed in March 1999. The facilities, which are located at the entrance to
Reservoir 4, include a caustic soda feed system to raise the finished water pH above 7.7
prior to distribution. Since 2001, the City has raised its finished water pH target range to
between 8.4 and 8.6 to help minimize the formation of certain disinfection byproducts
within the distribution system.
Between 1999 and 2000, the City completed two rounds of post-treatment lead and
copper monitoring at 60 customer taps. In each round, the 90th percentile results were
below the lead and copper action levels; therefore, the City became eligible for reduced
tap monitoring (i.e., 30 samples per event). The City completed two rounds of reduced
tap monitoring in July 2001 and July 2002, respectively, and the 90th percentile results
remained below the action levels. Since 2002, the City has been required to conduct
reduced monitoring at customer taps once every three-year cycle. The most recent round
of tap monitoring was performed during the first half of 2005, and the 90th percentile
results were 0.005 mg/L for lead and less than 0.2 mg/L for copper. Lead and copper
monitoring results since 1999 are summarized in Table 4-3. The next round of customer
tap sampling is scheduled for 2008.

The City is also been required to complete Water Quality Parameter (WQP) monitoring
for pH at the system entry point and at several locations within the distribution system.
Entry point pH samples are required at minimum biweekly at the outlet of Reservoir 4.
Under the regular schedule for pH monitoring within the system, the City is required to
conduct tworounds with at least 10 distribution samples during each six-month period.
In 2004, DOH approved the City's recommendation for optimal WQP (OWQP), which
included a minimum entry-point pH of 7.7 and minimum distribution system pH of 7.1.
The City collected 17 entry point pH samples and two rounds of at least 10 distribution
system samples during each six-month period in 2005. All samples were in agreement
with the OWQP; therefore, the City qualified for reduced monitoring.

West 517 Zone
Following designation of the West 517 Zone as a separate small water system in 2001,
the City performed two rounds of monitoring for lead and copper, with 10 customer taps
sampled each round. As shown in Table 4-4, the 90th percentile results were well below
the respective action levels, thus qualifying the West 517 Zone for reduced monitoring.
In addition, since the 90th percentile lead results were less than or equal to 0.005 mglL
and the 90th percentile copper results were less than or equal to 0.65 mglL, the West 517
Zone qualified for accelerated reduced monitoring. The accelerated reduced monitoring
requirements require the collection of five tap samples once every three-year cycle. The
City completed monitoring in July 2005, and the next round of tap sampling is scheduled
for 2008.
No requirement exists for WQP monitoring at entry points or within the distribution
system, since the West 517 Zone has remained compliant with lead and copper action
levels and is considered a small system.

4.4.5 Wellhead Protection Program
Regulatory Elements
According to WAC 246-290-135(3), public water systems are required to implement a
Wellhead Protection Program (WHPP) to protect their groundwater supplies. Source
water protection programs are planning tools to be used by water utilities to identify
potential sources of water contamination and to protect existing and future drinking water
supplies. The objective is to minimize risk of accidental releases of contaminants in areas
contributing water to the public water supply system. The three basic elements of a
source water protection plan are:
. Definition of the Wellhead Protection Area (WHP A) for the area of recharge directly
contributing to a water supply. A WHP A is defined as an area contributing to a
source 'vvithin a.specified ~mount of time.
o Inventory of land uses and identification of potential sources of contamination within
the WHP A or watershed.
. Management strategies including emergency spill response and contingency plans to
minimize or eliminate the possibility of potential contamination of the water supply.
Water Quality Review and RegulatOlY Compliance
4-9
2005 City of Bremerton Water System Plan
Bremerton Status
In 1996, the City prepared a WHPP for its well supplies in the Gorst Creek basin,
Anderson Creek watershed, and Manette peninsula. As part of this effort, the City
developed a conceptual hydrogeologic model for each of the aquifers, completed
vulnerability assessments, determined the time of travel zones for each source using the
EP A General Particle Tracking (GPTRAC) method, initiated the formation of a
countywide Wellhead Protection Committee (Kitsap County Groundwater Guardians),
delineated the WHP As for each source, completed inventories of potential contaminant
sources, and notified those sources regarding their inclusion in a WHP A. The City has
continued to survey the WHP A every two years for contaminant occurrence, and the
Critical Areas Ordinance limits potentially contaminating activities within the WHP As.
Regarding emergency planning, contamination of an individual aquifer could impact
Bremerton's supply capabilities. However, the aquifers utilized by Bremerton's wells are
separated hydrogeologically, and contamination would likely be contained to a single
aquifer. The contingency plan for such an emergency would be to use supplemental well
sources, apply for emergency water rights on Wells 21 and 22, and rely more on the
surface water source in the interim.
4.4.6 Total Coliform Rule
Regulatory Elements
The Total Coliform Rule (TCR) requires water systems to monitor their distribution
system for the presence of coliform bacteria, a surrogate used to indicate possible
contamination from fecal bacteria. The City performs monitoring as outlined in its
existing Coliform Monitoring Plan and Addendum to Bremerton Coliform Monitoring
Plan, the latter created specifically for the West 517 Zone. Monitoring is required at
representative sites on a monthly basis, with the sample quantity dependant on the size of
the population served. Community water systems with service populations between
50,001 and 59,000 (e.g., main system) are required to take 60 representative samples
monthly throughout the system. Non-community water systems with service populations
between one and 1,000 (e.g., West 517 Zone) are required to take one representative
sample from the system if no coliform detection existed during the previous month and
five representative samples if any coliform was detected during the previous month. All
samples testing positive for total coliform must be followed by repeat sampling and
additional testing to determine if E. coli is present.
The Surface Water Treatment Rule (SWTR) and WAC 246-290-694(3)(a) include several
additional provisions for coliform monitoring in unfiltered surface water systems. These

coliform sample at the entry point to the distribution each day that routine or repeat
coliform samples are collected from within the system. According to the SWTR, surface
water fecal coliform sampling is also required at least five days per week. This
Water Quality Review and Regulatory Compliance

requirement is further addressed later in the description of the Surface Water Treatment
Rules.
Under the TCR, two types of violations exist: acute and non-acute. An acute MCL
violation for coliform is based on the presence of either fecal coliform or E. coli in a
repeat sample or coliform presence in a repeat sample collected as a follow-up to a
sample indicating the presence of fecal coliform or E. coli. A non-acute MCL violation
for coliform occurs under the following conditions: a system collecting 40 or more
coliform samples per month (corresponding to a service population of at least 33,001) has
more than 5 percent of the routine samples taken in one month test positive for the
presence of total coliform, or a system collecting fewer than 40 coliform samples per
month has more than one coliform detection.
Bremerton Status
Main System
The City collects at least 60 routine coliform samples per month at locations throughout
the main system, as well as entry-point coliform sampling each day that routine or repeat
samples are collected. Of the 4,687. routine distribution system samples collected from
2000 to 2005, only 29 samples (0.7 percent) tested positive for coliform. Of these, four
tested positive for E. coli. In all cases, the City collected repeat samples in accordance
with the provisions of WAC 246-290-320, and none confirmed the coliform presence
indicated in the routine samples. The City also complied with the requirements to collect
source water fecal coliform and system entry-point coliform samples on days when the
maximum turbidity exceeded 1.0 NTU. No acute or non-acute violations existed during
this period.
West 517 Zone
The City typically collects two routine system samples per month from the West 517
Zone (unless a positive coliform detection existed the previous month, in which case the
City collects five routine samples). Of the approximately 120 routine distribution system
samples collected from 2001 to 2005, no samples tested positive for coliform or E. coli.
No acute or non-acute violations occurred during this period.
4.4.7 Surface Water Treatment Rules
Regulatory Elements
The Surface Water Treatment Rule (SWTR) was issued in 1989 and applies to water
systems using surface water or groundwater under the influence of surface water (GUI).
The SWTR addresses filtration, disinfection, and regulation of Giardia lamblia, viruses,
Legionella, heterotrophic plate count (HPC) bacteria, chlorine residual, and turbidity
levels of finished water. As an unfiltered system, the City is required to comply with the
filtration avoidance criteria addressed in WAC 246-290-690, which inciudes source water
monitoring and quality requirements, disinfection criteria, watershed control and
protection requirements, and monitoring requirements.
Water Quality Review and RegulatOlY Compliance
4-11
2005 City of Bremerton Water System Plan
The Interim Enhanced Surface Water Treatment Rule (IESWTR) was issued in 2001 and
builds upon the SWTR without replacing it. For unfiltered surface supplies, the IESWTR
requires addition of Cryptosporidium to the watershed control program wherever Giardia
lamblia is mentioned. This includes the identification and monitoring of activities that
may impact microbial water quality. The IESWTR also includes disinfection profiling
and microbial benchmarking provisions based on system-wide disinfection by-product
(DBP) levels.
Watershed Control Program
The SWTR requires the development, documentation, and implementation of a watershed
control program (WCP) for unfiltered surface supplies. According to the requirements of
WAC 246-290-135(4), the WCP must address watershed hydrology and characteristics,
land ownership, activities that may adversely affect source water quality, security and
access-related issues, and monitoring provisions. Also, for unfiltered surface supplies,
DOH must complete a sanitary survey once every five years and annual on-site
inspections to ensure adequacy of the watershed control program. The WCP has been
updated with this WSP.
Source Water Quality Conditions
For unfiltered surface supplies, the SWTR requires source water monitoring of fecal
coliform density and turbidity. According to requirements in WAC 246-290-694, the City
must collect fecal coliform samples on at least five separate days each week, including
whenever the source water turbidity exceeds 1.0 NTU. To remain in compliance, the fecal
coliform density must be less than or equal to 20/1 00 mL in 90 percent of samples for the
previous six months, and the turbidity cannot exceed 5.0 NTU when the supply is used
unless DOH determines that the event was:
. The result of unusual or unpredictable circumstances or;
. No more than two events occurred in the last 12 months, or no more than five events in
the last 120 months.
The SWTR permits operational adjustments, including temporary source shutdown
during turbidity episodes, providing that alternate supplies and/or finished water storage
are available and can be used to meet system demands.
Compliance with the total coliform MCL is also a required component of the filtration
avoidance criteria unless it can be shown that the violation was not related to source or
treatment deficiencies.

~.u....,~~..~.. ---"1n.. ~'''_'._~
For unfiltered surface waters, SWTR treatment requirements for Giardia lamblia and
enteric viruses must be met through disinfection. The disinfection requirements require
adequate CT (disinfectant concentration multiplied by contact time) be provided such that
3-log (99.9 percent) inactivation of Giardia ,lamblia and 4-log (99.99 percent)
inactivation of enteric viruses is achieved each day, resulting in inactivation ratios greater

2005 City of Bremerton Water System Plan
than or equal to one. Regarding Cryptosporidium, the IESWTR required a minimum of2-
log (99 percent) removal for filtered systems but did not impose any removal or
inactivation requirements for unfiltered systems.
System Water Quality Conditions
After treatment, the SWTR requires a minimum disinfectant residual of 0.2 mglL at the
point of entry to the distribution system at all times. Additionally, a detectable
disinfectant residual must be present in at least 95 percent of all distribution system
samples collected at the same time and location as coliform samples, according to WAC
246-290-451. Alternatively, samples may be analyzed for heterotrophic plate count
(HPC) bacteria. An HPC level of 500 colony forming units per milliliter (cfulmL) or less
is considered equivalent to a detectable disinfectant residual.
Bremerton Status
The City does not regularly pump surface water through the intertie to the West 517 Zone
and only uses it when CTs are met at Pump Station 3. Therefore, regulations pertaining to
the surface supply only apply to the main system. Since 1992, Bremerton has successfully
maintained its non-filtration status under the SWTR. The source waters utilized by the
City are excellent based on the following facts:
· Surface water quality continues to meet the requirements for filtration avoidance, and
· All groundwater sources appear to be hydraulically isolated from the influence of
surface water.
Table 4-5 provides a summary of the City's compliance status with regard to SWTR
requirements. These items are further discussed in the following sections.
Since the last WSP update in 1999, the following major changes and/or improvements to
the watershed, McKenna intake facilities, treatment (screening, chlorination), and/or
transmission have been made:
· The Utility contracts with the Bremerton Police Department for after hours facility
inspections;
· Seismic bracing of the dam intake tower; and
· Security upgrades to various facilities in response to post 9-11 concerns.

2005 City of Bremerton Water System Plan
Union River Watershed Control Plan
The City owns approximately 2,904 acres (98 percent) of the Union River watershed,
with the other 60 acres under outside ownership of Trinity Broadcasting and the
Department of Natural Resources. In 1996, the City completed Utility (Volume I) and
Forest (Volume II) Land Management Plans that address general management of City
owned land, including the Union River watershed. The City completed the City of
Bremerton Watershed Control Program to further define specific precautions taken to
protect the watershed. The WCP, which was approved by DOH, addresses watershed
hydrology, characteristics, land ownership, and security/access protocol. The original plan
was designed to address the 1989 SWTR and its provisions adopted by DOH regarding
requirements for remaining an unfiltered source (WAC 246-290-690). Those provisions
provided for more detailed monitoring of activities within the watershed, restricted access
gates, and enhanced watershed patrol and enforcement. According to the requirements of
the IESWTR, the WCP was updated in 2001 specifically to address control of
Cryptosporidium. The most recent update to the WCP was in 2006.
Union River Watershed Water Quality
The City collects Union River water supply samples for determination of fecal coliform
density according to the monitoring requirements in WAC 246-290-694. Owing to the
high quality of the surface supply, the City has maintained compliance with the filtration
avoidance criterion that at least 90 percent of samples over any running six-month period
have fecal coliform concentrations less than 20/100 mL. The observed frequencies of
fecal coliform concentrations below 20/1 OOml for the Union River System Intake
(consisting of the main stem with the seasonal addition of the West Branch) since 2000
has have averaged 97.6% percent, while the minimum six-month period was 95.5%
percent.
The City conducts continuous on-:line monitoring of raw water turbidity at the McKenna
Falls Intake facility during periods when the surface supply is in use. Figure 4-1 depicts
the maximum daily turbidity observations from January 2002 through December 2005.
Over this period, the maximum daily turbidity was less than 1.0 NTU rougWy 86 percent
of the time. No occasions occurred where the delivered water exceeded 5.0 NTU. The
City does have automatic intake shutdown capabilities should the source turbidity
approach 5.0 NTU. Bremerton generally shuts down at turbidities much less than this.

The City also performs voluntary environmental monitoring at several locations within
the Union River watershed in order to characterize water quality trends and ensure the
adequacy of its watershed control program. Monitoring is performed according to the
Monitoring Plan for the Union River Reservoir (last updated July 2004). A variety of
parameters, including nutrients, total organic carbon (TOC), algae, phyto- and zoo-
plankton, and physical characteristics, are assessed monthly.
Disinfection
The City feeds chlorine gas at McKenna Falls (and Wells 17 and 20) for primary
disinfection within the McKenna transmission pipeline. The disinfection compliance
point for the surface supply is the entrance to Reservoir 4. The City monitors chlorine
residual, pH, and temperature at four locations along the transmission main and uses
these data along with peak hourly flow measurements for each segment to determine the
overall CT achieved en route to Reservoir 4. Based on a review of daily CT profiles since
January 2002, the City has provided overJ-logGiardia lamblia inactivation each day the
surface supply was in use, with typical inactivation ratios between 2 and 6. The CT
required for 4-log inactivation of viruses is much less than that for 3-log Giardia lamblia;
therefore, the City has maintained compliance with both requirements.
System Water Quality
The City adjusts the chlorine feed rate to provide a target residual of 1.1 to 1.4 mglL at
the entrance to the distribution system at Reservoir 4. Experience shows that this target,
Water Quality Review and Regulatory Compliance

2005 City of Bremerton Water System Plan
along with individual dose targets for each of the chlorinated well supplies, has been
adequate to ensure a detectable chlorine residual throughout the system. The City also
maintains an automated system to shut down the surface intake if the residual drops
below a low-level set point, ensuring compliance with the 0.2 mg/L entry-point
requirement.
The City monitors chlorine residual within the distribution system at least once per day
and at the same time and location as routine and repeat coliform sampling. Based on a
review of daily monitoring records from January 2002 through December 2005, the City
performs an average of 77 chlorine residual samples per month. For all months during
this period with the exception of September 2004, all samples contained a detectable
residual and/or an HPC level below 500 cfu/mL. In September 2004, two of 97 samples
(2 percent) contained no residual and had HPC levels above 500 cfu per mL, which is still
in compliance with the requirements. Therefore, the system has remained in full
compliance with the distribution system water quality requirements of the SWTR.
4.4.8 Stage 1 Disinfectants/Disinfection By-Products Rule
Regulatory Elements
Disinfection by-products (DBPs) result from the reaction of natural organic matter
(NOM) and various inorganic precursors with chemical disinfectants. Toxicological
research has shown that many DBPs have carcinogenic and other adverse properties when
ingested for long periods of time. In 1979, the EPA enacted the Total Trihalomethane
Rule, which set an interim MCL for total trihalomethanes (TTHM) of 0.1 mg/L as a
running annual system-wide average based on quarterly monitoring within the
distribution system. This rule applied to water systems using a chemical disinfectant and
serving over 10,000 customers.
In 1998, the EP A promulgated the Stage 1 Disinfectants/Disinfection By-Products
(D/DBP) Rule to further reduce the DBP levels in drinking water. The Stage 1 D/DBP
Rule, which applies to all CWS and NTNC water systems that apply a primary or
secondary chemical disinfectant to their water supply, became effective in January 2002
for large systems (those serving 10,000 or more people) and January 2004 for small
systems (those serving less than 10,000 people).
The Stage 1 D/DBP Rule established new MCLs for chlorite, bromate, and the sum of
five haloacetic acids (HAAS) (0.060 mg/L) and established maximum residual
disinfection levels (MRDLs) for chlorine (4.0 mg/L), chloramines, and chlorine dioxide.
It also lowered the MCL for TTHM (0.080 mg/L) and set total organic carbon removal
requirements for systems using conventional filtration.
The DBP monitoring requirements under the rule depend on the system size (large or
small) and source of supply (surface water or groundwater). For the main system, which
is considered a large surface water system under the rule, routine monitoring
requirements include the collection of four paired (i.e., both TTHM and HAAS) samples
per quarter per plant (i.e., designated entry point) operated any time during that quarter.
Water Quality Review and Regulatory Compliance
4-17
2005 City of Bremerton Water System Plan
At least 25 percent of all samples collected each quarter must be from locations
representing maximum residence time in the system. The remaining samples must be
taken at locations representing average residence time in the distribution system and
representing the entire system, taking into account number of persons served, different
sources of water, and different treatment methods.
For the West 517 Zone, which is considered a small groundwater system under the rule,
routine monitoring requirements include the collection of one paired sample per year per
plant (i.e., designated entry point) during the month of warmest water temperature at a
location of maximum residence time. Compliance with the respective MCLs is
determined based on the running annual arithmetic average (RAA) of quarterly averages.
Quarterly averages are determined using a flow-weighted average of individual plant
averages.
For both the main system and the West 517 Zone, chlorine residual samples must be
collected at the same time and location as coliform samples. Compliance with the
chlorine MRDL is based on theRAA, computed quarterly, of monthly averages of all
samples from each system.
Reduced monitoring is permitted under the rule if the RAA of TTHM and HAA5 results
drop below 0.04 mglL and 0.03 mglL, respectively, over a 12-month sampling period.
However, full sampling must be re-implemented if RAA TTHM levels exceed 0.06 mglL
or HAA5 levels exceed 0.045 mglL.
Bremerton Status
Main System
Prior to implementing the Stage 1 D/DBP Rule, the City submitted to DOH a technical
report entitled, Determination of "Treatment Plant" for Compliance with the Federal
Disinfectants/Disinfection Byproducts Rule. This report provided justification for the use
of the four plant designations T -1 through T -4 (See Table 4-1 ). Well 14 was considered
part of plant T-3 (rather than T-5), since it draws from the Manette Sea Level Aquifer
along with Well 13. For each of the plant locations, four distribution sample locations,
one representing maximum residence time and three representing average residence time,
were selected using zones of influence determined from the Bremerton water system
model.
The City began quarterly monitoring under the rule in January 2002 in accordance with
its Monitoring Plan for Compliance with the Disinfectants/Disinfection Byproducts Rule
(last updated August 2004). After the first quarter of 2003, the RAAs for TTHM and

Figure 4-2 depicts the main system monitoring results for TTHM and HAA5 since
January 2002. The City has continued to meet both the Stage 1 MCLs as well as the
levels necessary to remain on the reduced monitoring schedule. The maximum RAA for
TTHM (0.051 mg/L) and HAA5 (0.036 mg/L) occurred in the first quarter of 2004. The
highest single TTHM observation (0.073 mg/L) occurred at the maximum residence time
for plant T-1 in the third quarter of 2004. The highest single HAA5 observation (0.066
mg/L) occurred at the maximum residence time for plant T-2 in the second quarter of
2003.

2005 City of Bremerton Water System Plan
The City collects an average of 77 distribution system chlorine residual measurements
each month from the main system, with individual sample results ranging from non-detect
to 1.2 mg/I. Since January 2002, the main system chlorine RAA has varied between 0.6
mg/L and 0.79 mg/L; therefore, the City has remained in compliance with the chlorine
MRDL.
West 517 Zone
For the purposes of Stage 1 DBP monitoring and compliance, Wells 15, 18, and 19 are
considered to be a single plant, since they all draw from the same aquifer. The monitoring
requirements became effective for this system in January 2004, as it serves less than
10,000 people. The City collects its annual samples in August, the month of warmest
water temperature and has met the respective MCLs during both 2004 and 2005
sampling. In August 2004, the TTHM and HAA5 results were 0.0058 and 0.0037 mg/L,
respectively. In August 2005, the TTHM and HAA5 results were 0.004 mglL and non-
detectable, respectively.
The City collects an average of two distribution system chlorine residual measurements
each month from the West 517 Zone, with individual sample results ranging from 0.19 -
to 1.44 mg/L. Since January 2002, the West 517 Zone chlorine RAA has varied between
0.6 mg/L and 1.06 mg/L; therefore, the City has remained in compliance with the chlorine
MRDL.
4.4.9 Consumer Confidence Reports and Public Notification Rule
Regulatory Elements
Under the Consumer Confidence Report (CCR) Rule promulgated in 1998, water systems
are required to provide an annual CCR on the source of their drinking water and levels of
any contaminants found. According to WAC 246-290-72001, these reports are only
required of community water systems and do not apply to the West 517 Zone. The annual
report must be supplied to all customers and must include:
· Information on the source of drinking water
· A brief definition of terms
· If regulated contaminants are detected, the MCLG, MCL, and the level detected
· If an MCL is violated, information on health effects
· If EP A requires it, information on levels of unregulated contaminants
WAC 246-290-72001
While the CCR provides annual "state-of-the-water" reports, the Public Notification Rule
(PNR) directs utilities in notifYing customers of acute violations when they occur. The
PNR was revised in May 2000 and outlines public notification requirements for violations
of MCLs, treatment techniques, testing procedures, monitoring requirements, and a
variance or exemption. If violations have the potential for "serious adverse effect,"
Water Quality Review and RegulatOlY Compliance

2005 City of Bremerton Water System Plan
consumers and the State must be notified within 24 hours of the violation. The notice
must explain the violation, potential health effects, corrective actions, and the need for
consumers to use an alternate water source. Notice must be made by appropriate media or
posted door-to-door. Less serious violations must be reported to consumers within 30
days in an annual report or by mail or direct delivery service within one year, depending
on the severity of the violation.
Bremerton Status
The City's first CCR was distributed in October 1999. As required, the City has
distributed CCRs to its customers prior to July 1 each year since 1999. The City's 2005
CCR is located on-line at http://www.ci.bremerton.wa.us
4.4.10 Operator Certification
The 1996 SDW A amendments require that states develop and implement an operator
certification program. The regulation sets out minimum guidelines for such a
certification program, including operator classification and qualifications. These sections
of the regulation require that:
· Each treatment facility and/or distribution system be placed under the direct supervision
of a certified operator;
· Operator certification must be equal to or greater than the system classification being
operated;
· At least one certified operator be available on every shift;
· Operators must pass a validated exam demonstrating skills, knowledge, ability, and
judgment necessary for the system classification; and
· Each operator has a high school diploma, GED, or State approved experience and
training.
While the responsibility for developing the program lies with DOH, systems such as
Bremerton are required to bring all operators up to the level of certification as required.
Bremerton Status
As discussed in Chapter 6, Operation and Maintenance Program, all water system
managers, supervisors, and operators have the appropriate water certification from DOH.

Promulgated Rules Under the Safe Drinking Water Act
4.5.1 Long Term 2 Enhanced Surface Water Treatment Rule
Regulatory Elements
The Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) was published
in the Federal Register on January 5, 2006. The rule was developed as part of the Stage 2
Microbial/Disinfection By-Products cluster, which was intended to improve public health
protection against waterborne pathogens, specifically Cryptosporidium, while addressing
risk trade-'-offs associated with exposure to chemical disinfectants and DBPs. The
LT2ESWTRappliesto public water systems that distribute or wholesale surface water or
groundwater under the direct influence of surface water (e.g., Subpart H systems). It
builds upon, without replacing, the requirements of the SWTR and IESWTR.
The LT2ESWTR seeks to lower the concentration of Cryptosporidium in finished
drinking water supplies to less than one oocyst per 10,000 liters. The approach involves
the identification of source water vulnerability to Cryptosporidium occurrence and
implementation of treatment and control strategies appropriate to the level of risk. For
the first time, the LT2ESWTR imposes Cryptosporidium treatment requirements for
unfiltered surface water systems. This was mandated to ensure a comparable level of
public health protection similar to filtered systems. The rule also contains requirements
for disinfection profiling and benchmarking as well as measures to protect uncovered
finished water storage reservoirs from contamination risks.
The key elements of the rule applicable to the City of Bremerton include:
· Initial source water monitoring
· Determination of mean Cryptosporidium concentration
· Disinfection profiling and benchmarking
· Implementation of treatment options from the microbial toolbox
· Future source water monitoring
/nitialSource Water Monitoring
Under the L T2ESWTR, surface water systems that serve 10,000 or more people (e.g.,
large systems) must conduct monthly source water monitoring of Cryptosporidium for 24
consecutive months. Historical data may be "grandfathered," providing they meet specific
eligibility requirements established in the rule.
Water Quality Review and Regulatory Compliance
4-22
2005 City of Bremerton Water System Plan
Disinfection Requirements
The LT2ESWTR requires that unfiltered surface water systems provide Cryptosporidium
treatment via disinfection. The level of inactivation required is either 99 percent (2-log)
or 99.9 percent (3-log), depending on the mean oocyst concentration determined from the
initial source water monitoring period. Unfiltered systems will be required to use
chlorine dioxide, ozone, or ultraviolet (UV) irradiation to meet the Cryptosporidium
inactivation requirement and at least two separate disinfectants in order to meet the
combined Cryptosporidium, Giardia lamblia, and viral inactivation requirements. Each
disinfectant must be able to achieve the total inactivation required for Cryptosporidium,
Giardia, or viruses separately.
Disinfection Profiling
Disinfection profiling involves tracking the inactivation of specific pathogens over a
period of time. The LT2ESWTR includes disinfection profiling and benchmarking
requirements to ensure water systems maintain adequate protection against microbial
pathogens as they take steps to simultaneously comply with the Stage 2 DBP Rule. Water
systems will be required to develop Giardia and virus disinfection profiles and calculate
microbial benchmarks if they plan to make a significant change to their disinfection
practice following the initial source water monitoring period. A significant change is
defined as moving the point of disinfectant application, changing the disinfectant, and/or
changing the disinfection process.
Future Source Water Monitoring
Water systems will be required to conduct additional monitoring in the future to confirm
or revise the initial assessment of source water quality. The additional monitoring will be
required beginning six years after initial bin classification. Over the next several years,
the EP A may modify the sampling or analytical requirements from those required for the
initial round of monitoring. )
Bremerton Status
The City of Bremerton will need to comply with the LT2ESWTR for its Union River
Supply according to the schedule established for water systems serving 50,000 to 99,999
people. Since the Main Stern and West Branch supplies are blended prior to collection
and treatment, they are considered a single source under the rule.
Initial Source Water Monitoring
As part of its Watershed Control Program, the City has been periodically monitoring
source water at the Union River reservoir for Cryptosporidium since 1994. Generally,
between two and four samples are collected each year. Since sampling is not performed
monthly, the historical Cryptosporidium data will not be acceptable for grandfathering.
Therefore, the City will be required to either complete 24 months of source water
monitoring (beginning no later than April 1, 2007) or submit its intent to provide 3-log
Cryptosporidium inactivation (assuming it retains its unfiltered status). The City will be
Water Quality Review and Regulatory Compliance
4-23
2005 City of Bremerton Water System Plan
required to develop a source water sampling schedule and provide it to the EP A no later
than January 1, 2007.
The estimated analytical cost for each Cryptosporidium sample is $450 (year 2006 $).
Assuming 24 source water samples plus two required matrix spikes are collected, the cost
to complete initial monitoring is estimated at $12,000.
In November 2005 (prior to promulgation of the final rule), the City prepared a draft Long
Term 2 Enhanced Surface Water Treatment Rule Monitoring Plan. The plan will be
reviewed and updated as necessary to ensure it conforms to the requirements of the final
rule.
Disinfection Requirements
The City currently uses only chlorine disinfectant to meet the SWTR inactivation
requirements for Giardia lamblia and virus. If it elects to keep the Union River supply
unfiltered, the City will be required to implement an additional disinfectant (chlorine
dioxide, ozone, or UV irradiation) for Cryptosporidium inactivation. Each disinfectant
must be able to achieve the total inactivation required for Cryptosporidium, Giardia
lamblia, or viruses separately. The City must have the new disinfection facilities installed
and on-line no later than October 2012 unless a separate compliance agreement is
negotiated with DOH. As part of this WSP update, the City is evaluating approaches to
comply with the additional Cryptosporidium treatment requirements.
Disinfection Profiling
Although the City will be required to provide an additional disinfectant barrier to meet
the Cryptosporidium inactivation requirement, it would only be required to profile and
benchmark if it elected to modify its existing chlorination practices. The City currently
performs monitoring along the transmission pipeline leading from the McKenna Falls
intake to Reservoir 4 in order to determine Giardia lamblia inactivation and residual at
the system entry point. These data (and the calculated daily profiles) may be eligible for
grandfathering. The City would consult with DOH in advance of making any changes to
its existing chlorination practices.
4.5.2 Stage 2 Disinfectants/Disinfection By-Products Rule
The Stage 2 DBP Rule was published in the Federal Register on January 4,2006. The
rule was developed to provide more equitable protection against DBPs on a system-wide
basis by changing the compliance monitoring provisions. The Stage 2 DBP Rule applies
to community and NTNG water systems that serve drinking water treated with aprimary

· Re-establishes the location and number of OBP monitoring sites. The rule requires
systems to conduct an Initial ~istribution System Evaluation (lOSE) to select Stage 2
OBP monitoring locations in areas of the distribution system with elevated OBP
levels. Additionally, the final Stage 2 OBP Rule requires systems to determine
monitoring requirements based on population.
· Establishes DBP operational evaluation levels for each monitoring site. These levels
are calculated as 25 percent of the sum of the two previous quarter's results plus twice
the current quarter's monitoring result. A system exceeding this level is required to
conduct an operational evaluation or evaluate their distribution system operations to
determine ways to reduce OBP levels. The system is required to notify the state of an
operational evaluation level exceedance and submit evaluation results within 90 days
of the exceedance.
· Requires consecutive systems purchasing drinking water carrying a disinfectant to
implement Stage 2 OBP requirements on the same schedule as the largest water
system in their combined distribution system.
The first step in complying with the Stage 2 OBP Rule is conducting an lOSE with the
goal to identify areas with routinely higher OBP concentrations than other areas in the
distribution system and use this information to select monitoring locations for long-term
Stage 2 OBP compliance monitoring. The lOSE requirement can be met in four ways:
. Very Small System Waiver - Systems serving less than 500 customers that qualify for
this waiver are exempt from IDSE requirements.
· 40/30 Certification - This approach allows systems to meet the lOSE requirement by
certifying that all individual Stage 1 TTHM and HAA5 compliance monitoring results
or equivalent OBP data collected over a specified 2-year period have met the
following criteria: TTHM :S 0.040 mg/L and HAA5 :S 0.030 mg/L. Systems must
submit the required documentation to the primacy agency.
. Standard Monitoring Program (SMP) ~ Systems conduct one year of monitoring in
the distribution system to identify high OBP locations and must submit a SMP Plan
and lOSE report to the primacy agency as part of the lOSE process.
. System Specific Study (SSS):
o
Using Existing Monitoring Oata - Systems can meet lOSE requirements using
existing monitoring data. The EPA has established criteria the existing data must
meet in order to be used to meet the SSS requirement. Systems must submit an

Consecutive systems purchasing some or all of their water from another system and
systems that sell water wholesale must comply with the Stage 2 DBP Rule on the same
schedule as the largest system in the combined distribution system. A combined
distribution system is the interconnected distribution system consisting of the distribution
systems of wholesale systems and consecutive systems receiving finished water from the
wholesale system(s). However, Stage 2 sampling requirements are based on the retail
population served by each individual system, not the combined distribution system. The

Bremerton Status
Main System
The main system will need to comply with Schedule 2, which requires submission of an
IDSE plan no later than April 1,2007. The main system will not be eligible for an IDSE
40/30 waiver, since some sample results since October 2004 have exceeded 0.040 mg/L
for TTHM and 0.030 mg/L for HAAS. With regard to Stage 2 compliance monitoring,
the City will ultimately need to select a total of eight monitoring locations within the
main system (three for maximum TTHM, three for maximum HAAS, and two existing.
Stage 1 monitoring locations). Monitoring of these sites will be required no later than
October 1, 2012, at which point the LRAA compliance approach will take effect.
Based on historical DBP data from Stage 1 sampling, it appears the City may be able to
comply with the Stage 2 DBP Rule without making major treatment or operational
changes. However, the Stage 1 sampling locations may not be representative of maximum
TTHM and HAAS locations within the system. The IDSE will be required to identify
these worst-case sites. As part of this WSP update, the City is evaluating its IDSE
compliance options.
West 517Zone
Since the West 517 Zone is a NTNC system serving fewer than 10,000 people, the City
will not have to complete IDSE requirements for this system. The City will still be
required to comply with the routine Stage 2 monitoring requirements and .MCLs
according to Schedule 4 in Table 4-7. For groundwater systems serving less than I 0,000
people, the rule requires the collection of paired samples at two sites per plant once per

year. The sites should represent locations of maximum TTHM and HAAS, respectively.
Therefore, the City will be required to provide a monitoring plan to DOH with
justification of the sites selected.
4.6 Anticipated Regulations
Several new or revised regulations are anticipated over the next six years. It is important the City
remain apprised of the development of these regulations. Table 4-8 presents a listing of

In August 2005, the EP A proposed a second Unregulated Contaminant Monitoring Rule
that includes two lists of contaminants for which some systems will be required to
monitor. All public water systems serving more than 10,000 people will be required to
conduct assessment monitoring for 11 contaminants on the Assessment Monitoring List
at distribution system entry points. Systems serving more than 100,000 people and
selected smaller systems will be required to conduct screening monitoring for 15
contaminants on the Screening Survey List This list includes contaminants that will be
monitored at distribution system entry points and within the distribution system. This
monitoring \vill be req"uired during" a: 1.2~month period between 2007 and 2010.

4.6.2 Radon Rule
A proposed Radon Rule was released in November 1999 providing two options for the
maximum level of radon allowable in community water supplies. The SDW A has
directed the EP A to not only propose and finalize an MCL for radon in drinking water,
but also to make available a higher alternative MCL (AMCL) accompanied by a
multimedia mitigation (MMM) program to address radon risks in indoor air. The
proposed MCL is 300 pCi/L, and the proposed AMCL is 4,000 pCi/L. The drinking
water standard that would apply to the City depends on whether or not the State develops
a MMM program. However, it is likely that these preliminary standards will change if
the MMM program becomes regulated under the EP A Indoor Air Office.
Bremerton Status
Radon sampling conducted in 1994 at all wells showed radon levels ranging between 80
and 255 pCi/L, all below the proposed MCL of 300 pCi/L. It does not appear as though
the rule will impact the main system, and the rule as proposed does not apply to NTNC
systems such as the West 517 Zone.
4.6.3 Lead and Copper Rule Revisions
The EP A initiated a review of LCR implementation in 2004 to determine if national lead
levels are increasing. As a result of this effort, the EP A identified a series of areas in
which changing the existing regulation would be beneficial. Table 4-9 lists the nine areas
that will be revised. The EP A anticipates issuing proposed revisions in early 2006.

risk of exposure to waterborne pathogens from fecal contamination. This type of
contamination may reach groundwater supplies through various sources, such as septic
systems or stormwater runoff.
Water Quality Review and Regulatory Compliance
4-29
2005 City of Bremerton Water System Plan
The GWR applies to all water systems that distribute groundwater not treated to 4-log
(99.99 percent) inactivation or removal of viruses. For the purposes of compliance with
the proposed GWR, sources that are treated and continuously achieve 4-log inactivation
or removal of viruses are considered to be "disinfected." The sources that are treated but
do not meet this criterion are not considered to be "disinfected" sources.
The proposed GWR has five major components:
· System sanitary surveys conducted by the State to identify significant deficiencies;
· Hydrogeologic sensitivity assessments conducted by the State for ground water
sources that are not disinfected;
· Source water monitoring for indicators of fecal contamination by systems that do not
disinfect and also rely on a hydrogeologically sensitive aquifer or have detected fecal
indicators within the system's distribution system;
· Compliance monitoring for systems that disinfect to ensure they reliably achieve 4-log
inactivation or removal of viruses; and
· Corrective action by any system with significant deficiencies or positive microbial
samples indicating fecal contamination.
System Sanitary Survey
The GWR will require states to conduct sanitary surveys for all groundwater systems at
least once every three years. At a minimum, the surveys must cover the following
elements:
· Source
· Treatment
· Distribution system
· Finished water storage
· Pumps and pump facilities and controls
· Monitoring/reporting/data verification
· Water system management and operations
· Operator compliance with state requirements
Within 30 days of conducting each survey, the State must provide each system with a list
of observed significant deficiencies. After receiving a list of significant deficiencies,
systems have 90 days to take action to correct the deficiencies or submit a plan to the
State for making these corrections. For the proposed GWR, a significant deficiency is a
defect in design, operation, or maintenance or a failure or malfunction of the sources,
treatment, storage, or distribution system the State determines to be causing or has
potential for causing the introduction of contamination to the water delivered to
consumers.
Water Quality Review and Regulatory Compliance
4-30
2005 City of Bremerton Water System Plan
According to the proposed rule, systems that treat groundwater sources for 4-log
inactivation or removal of viruses or that have an outstanding performance record in all
the sanitary survey elements with no TCR violations since the last survey may move to a
surveying schedule of once every five years.
Hydrogeologic Sensitivity Assessment
The proposed GWR requires states to identify systems with higher likelihood for
contamination by waterborne pathogens from fecal contamination. Assessing
hydrogeologic sensitivity for all non-disinfecting groundwater sources will identify these
systems. Hydrogeologic sensitivity will be determined by the state using the type of
aquifer as a sensitivity indicator. The EP A indicates that wells obtaining water from a
karst, fractured bedrock, or gravel aquifer are sensitive to contamination unless protected
by a hydrogeologic barrier. If a physical barrier is present, this can void the determination
that an aquifer is "sensitive," but the specific criteria for such an exemption will be
developed by individual states.
Source Monitoring
The GWR requires three types of monitoring: (1) routine monitoring; (2) triggered
monitoring; and (3) monitoring for systems with disinfected groundwater sources.
Routine monitoring requirements apply to sources that are not disinfected and are
considered to be hydrogeologically sensitive. Triggered monitoring requirements apply to
systems with grQundwater sources not considered disinfected and producing positive total
coliform samples in the distribution system. These monitoring requirements are intended
to identify the possible presence of fecal contamination at the source. Monitoring for
disinfected sources verifies that continuous 4-log inactivation of viruses is achieved.
Corrective Action
The GWR requires water systems to implement specific actions after evidence of
contamination has been found in their system. If the State notifies a system of a
significant deficiency, the system must correct the deficiency, provide an alternate water
source, or implement treatment to reliably achieve 4-10g inactivation or removal of
viruses. If the system determines the Source water is contaminated, the system must do at
least one of the following: eliminate the source of contamination, correct the significant
deficiency; provide alternate source water, or provide treatment to reliably achieve at least

The GWR couldi1llpact gIoundwater supplies inboth the main system and the West 5i7
Zone. The City currently provides chlorine disinfection at each well with the exception
of Well 19. It is unknown whether the existing chlorination practices are capable of
providing 4-10g virus inactivation and would be classified as "disinfected" under the
GWR. If the City wishes its well supplies to be considered "disinfected," it will have to
demonstrate the ability to continuously achieve 4-log virus inactivation to DOH and then
Water Quality Review and RegulatOlY Compliance

2005 City of Bremerton Water System Plan
operate the disinfection systems to ensure this criterion is always met (e.g., provide
continuous monitoring and notify DOH any time chlorine residual falls below the state-
determined residual disinfectant concentration for more than four hours). For sources that
are not disinfected or for which the City does not wish to pursue "disinfected" status, the
City is prepared to cooperate with the state in its evaluation of hydrogeologic sensitivity
and the additional measures needed at each well to ensure compliance with the GWR.
4.6.5 Total Coliform Rule Revisions
As part of its six year review of existing regulations, EP A has determined the need to
revise the TCR. Revisions may include requirements to address finished water quality in
the distribution system and evaluate additional or alternative monitoring strategies that
would be more cost-effective and maintain or improve public health. As part of the
process for determining the appropriate revisions to this rule and the need for a future
Distribution System Rule, a series of white papers were developed by EP A and other
groups in 2002 to describe potential health risks in the distribution system. These papers
covered the following topics:
. Intrusion
. Cross-connection control
. Aging infrastructure and corrosion
. Permeation and leaching
. Nitrification
. Biofilms and bacterial growth
. Covered storage
. Decay in water quality over time
. New or repaired water mains
In addition, EP A and the American W ater Works Association are currently
preparing issue papers related to developing revisions to the TCR. These papers will
cover the following distribution system topics:
· Indicators of water quality
· Effectiveness of disinfectant residual
e Compliance with the existing TCR
· Hazard analysis and control strategies
· Accumulation of inorganic contaminants
· Nutrient availability
· Causes of contaminant events and positive coliform samples
e Total coliform sample invalidation

Bremerton Status
The date for a proposed revised TCR rule and/or Distribution System Rule is uncertain at
this time. However, any developments with either rule will likely have an impact on the
City. It is quite possible these rules will include the use and documentation of best
management practices within the distribution system. Cross connection control may be a
primary focus. As part of this WSP update, a detailed review of the City's cross
connection control program was conducted and is described in Section 6.
4.6.6 Potentially Regulated Contaminants
In addition to these anticipated regulations, the City will track potential regulations by
keeping up-to-date with the Contaminant Candidate List (CCL). The CCL is the primary
source used by the EP A for establishing priority contaminants that may face future
regulation. In February 2005, the EP A issued the second CCL, which is comprised of 51
contaminants (nine microbial and 42 chemical) included on the previous list. The CCL-2
includes at least three parameters, namely atrazine, methyl-t-butyl ether (MtBE), and
perchlorate, that the drinking water industry anticipates will be regulated in the future.
The EP A will determine whether the CCL-2 contaminants should be pursued for future
regulations in August 2006.
Bremerton Status
As part of its VOC monitoring efforts, the City also analyzes for MtBE. Samples for each
of the five designated entry points in the main system and the three wells in the West 517
Zone have been non-detectable for MtBE. As part of the UCMR monitoring in 2002 and
2003, the City analyzed for perchlorate in each of the main system designated entry
points. All results were below the detection limit. Should these contaminants be
regulated in the future, it does not appear as though the City's current sources would be
affected.
4.7 Summary of Regulatory Status
A review of monitoring procedures and water quality results from 2000 to 2005 indicates the
City has been in full compliance with all effective federal and state drinking water regulations for
both its main system and the West 517 Zone. Table 4-10 provides a summary of applicable
effective and promulgated regulations, the City's compliance status, and action plans.
The recently promulgated L T2ESWTR and Stage 2 DBP Rule will each have a significant impact
on the monitoring, treatment, and operations of the City's water systems. By April 2007, the
City will develop and submit plans forCryptosporidium monitoring of its Union River supply
and its IDSE approach for the main system. By October 2012, the City will provide additional
treatment of its surface supply to remove or inactivate Cryptosporidium. Also in 2012, the City
will begin monitoring nev/ly selected DBP sites and convert to the more rigorous LRAA
compliance approach.

5.1 Introduction
The transmission and distribution system for Bremerton's Main System is comprised of seven
pressure zones, 291 miles of pipe, 16 treated water reservoirs, 10 pump stations, five booster
pump stations, more than 20 pressure-regulating valves, two zone interties, and five interties with
other water systems.
The transmission and distribution system compnsmg Bremerton's West 517 Zone System
includes one pressure zone with 11 miles of pipe, two treated water reservoirs, one pump station,
one firelbooster pump station, four pressure-regulating valves, and one intertie with the
Bremerton Main System.
A detailed description of these facilities is provided in this section.
5.2 Pressure Zones
The City of Bremerton Main System's six pressure zones serve customers in East and West
Bremerton and are named accordingly as shown below. The West 580 Zone is currently under
construction and anticipated to be in operation before the end of 2006.

The Bremerton West 517 Pressure Zone System consists of only one pressure zone, which is the
West 517 Pressure Zone.
These pressure zones are illustrated in the Water System Schematic (Figure 1-3). Hydraulic
gradients within the zones are generally controlled by the water levels in the system reservoirs.
Service pressures within the zones are maintained at acceptable levels under normal, peak, and
emergency operating conditions. A pressure of 30 psi must be available at all service connections
under peak hourly demand conditions. Five small closed zones are served by booster pump
stations. A description of each pressure zone is presented in Table 5-1.

5.3 Control Valves
The Bremerton Main System has 25 pressure-regulating valves and the Bremerton West 517
Zone System has four. These valves are detailed in Table 5-2 and include installations for
reducing pressure, pressure relief, and pressure zone intertie. Pressure reducing stations allow
water to flow from higher pressure zones to lower pressure zones without over-pressurizing the
lower zone. Pressure relief valves prevent over-pressurization by relieving excess pressure to a
lower pressure zone or to the atmosphere.
A number of the valves are an integral part of the day-to-day operation of the system and provide
water to lower elevations at acceptable pressures. Several pressure reducing stations operate only
in an emergency capacity, providing water to the lower zones when the pressure downstream
drops below preset levels during very high demands. This condition would only occur during a
system failure, a large fire demand, or some other uncommon event.
The Water Utility currently includes two zone interties that allow water to flow from higher
pressure zones to lower pressure zones.
5.4 Interties with Other Water Systems
The Utility has interties with five other water systems, as indicated previously in Table 3-8 and 5-
2. Most of these interties provide water from Bremerton to neighboring water districts. Water
in the West 580 Zone is mixed with water from the Port Orchard system. The North Perry
intertie could provide water to Bremerton, although it has never been used for this purpose. It is
meant to provide an emergency intertie with the North Perry Avenue Water District. One intertie
is used to provide surplus water to the City of Port Orchard.
A system intertie exists between the Bremerton Main System and the Bremerton West 517 Zone
System at Pump Station 3. Water can either be pumped from the surface water transmission
main to the West 517 Zone (as long as Surface Water Treatment Rule requirements are met) or
water can be gravity fed from the West 517 Zone to the West 256 Zone transmission main.

5.5 Pump Stations
One booster station and five water pump stations are located in the East Bremerton distribution
system. Pump Stations 11, 14, and 16 draw water from the East 240 Zone and raise it to the East
398 Zone, filling Reservoirs 12, 13, 17, and 20. Pump stations 12 and 13 in the East 398 Zone
provide water to Reservoirs 15 and 18 in the East 490 Zone. Booster Station 5 is an in-line
booster that draws water across the Port Washington Narrows from the West 256 Zone into the
East Zone 240.
Five water pump stations and five booster stations are located in the West Bremerton distribution
system. Pump Station 2, located at Anderson Creek, is the largest active station in the system and
provides water to the West 256 Zone from the Anderson Creek wellfield. The Anderson Creek
wells pump at a constant rate to the pump station aeration basin. The well water is chlorinated
and pumped as needed into the system. Variable frequency drives allow control of the pump
station to prevent discharge of groundwater into Anderson Creek. Pump Stations 4 and 17 draw
water from the West 256 Zone to supply the West 440 Zone by maintaining the level in
Reservoirs 6 and 8. Pump Station 8 supplies water to the West 650 Zone and Reservoir 23.
Booster Stations 3, 6, 7, and 9 provide water as necessary at an acceptable pressure to the closed
zones. The pump stations are described in Table 5-3.
The West 256 Zone System includes the Pump Station 3 intertie pump station and Booster
Station 10, which provides fire flow and pressure to the Airport and Industrial Park at the Port of
Bremerton.
Pump Station 2a is currently under construction to be completed in 2006 and will provide water
from the West 256 Zone to the West 580 Zone and the Port Orchard McCormick water system
and Port Orchard's 0.45 MG reservoir.

Transmission and Distribution System
5.6 Transmission and Distribution Piping
The City of Bremerton has an extensive network of transmission and distribution piping ranging
in size up to 36 inches in diameter. Pipe inventory consists of approximately 291 miles of pipe
in the Bremerton Main System and 11 miles of pipe in the West 517 Zone System with the
majority being 6- and 8-inch diameter distribution piping. A summary of the quantity of pipe by
diameter is provided in Table 5-4.
5.6.1 Transmission Piping
Transmission main piping is used to move large quantities of water from one area of the
system to another, generally without service connections, and includes the pipe bringing
water from the McKenna Falls Intake Facility and the three pipes crossing the Port
Washington Narrows. The transmission pipe supplying water from the McKenna Falls
Intake Facility ranges in size from 24 inches to 36 inches in diameter. The pipeline is
approximately six miles long and supplies water to the 11 MG System Control Reservoir
4. Flow in the transmission pipe is controlled by a motor-operated oscillating butterfly
valve adjacent to the Twin Lakes area. The control valve at Casad Dam controls flow
down the streambed to the pipe intake at the McKenna Falls Intake Facility. Both of
these valves can be remotely controlled at the Utility's Olympus facility.
Two transmission mains supported on bridges cross the Port Washington Narrows and
provide water to East Bremerton. A 12-inch water main is supported from the Manette
Bridge, and a 20-inch water main is supported on the Warren Avenue Bridge. A third 18-
inch diameter submarine line crosses from Snyder Avenue to Lebo Boulevard. These
pipelines transfer water from the West 256 Zone to the East 240 Zone.
In 1998, the City of Bremerton completed a new 36-inch diameter transmission main
between Gorst and Reservoir 4. This main replaced a 40-year-old, 24-inch diameter cast
iron main, increased system capacity, and increased chlorine contact times within the
pipe. During this project, the City also constructed an 18-inch diameter transmission
main in Sherman Heights Road linking the 24-inch Sherman Heights transmission main
and an I8-inch transmission main in State Route 3. The 36-inch transmission main
conveys water from McKenna Falls, while the Sherman Heights main conveys
groundwater from the Anderson Creek wellfield.
The 36-inch main and the Sherman Heights main are interconnected and valved at Gorst
to provide better separation of surface water and groundwater supplies and redundant
transmission pathways from both the McKenna Falls and the Anderson Creek wellfields.
This is the first phase of the City's plan to upgrade its primary surface water transmission
system, as the 28-inch diameter steel is nearing the end of its service life. The second and
third phases, included in the City's Capital Improvement Plan for 2006-2025, will replace
the transmission main all the way to the McKenna Falls Intake Facility with 36-inch
ductile iron pipe.
Transmission and Distribution System
5-9
2005 Bremerton Water System Plan
5.6.2 Distribution Piping
The distribution system is a grid of 4- to 12-inch mains comprised of pve, cast iron,
ductile iron, steel, galvanized steel, and asbestos cement. Ductile and cast iron pipe make
up the majority of the system. Flow within the system is generally from west to east. The
system has 1,610 fire hydrants and 5,726 valves throughout to provide Utility customers
with fire protection.
Bremerton has a program to replace substandard mains (defined as <3 inches).
Replacement is prioritized based on head loss, age of pipe, size, maintenance problems,
and customer complaints. Approximately $300,000 is budgeted each year to address
substandard main replacement. Planned projects to address larger main projects are listed
in the appendix as "Distribution Improvements" and are budgeted separately from the
substandard mains.

6.2 System Operation and Control
6.2.1 Components
Details on water supplies and transmission and distribution are provided in Sections 3 and
5. Water system component relationships are illustrated in Figures 1-2 and 1-3.
6.2.2 Normal and Alternative Operation
Water operations and maintenance are located in two facilities as described below:
3027 Olympus Drive
100 Oyster Bay Road
Water resources supply and treatment operation Water distribution maintenance
Customer billing Water distribution construction
Engineering Meter reading and maintenance
Environmental monitoring Customer response and dispatch
Administration Cross connection control
Fleet maintenance
Electronics and communications
Inventory control and warehouse
Under normal operation, system data are received and recorded at the Olympus Drive
Water Operations Center via a computerized SCADA system. Alternative operation
typically includes both remote automatic and manual or "hand" operation. In the event of
SCADA failure, facilities can be operated by local hand operation. Operations and
maintenance procedures specifY normal, alternate, and emergency procedures for
operation of supply pumps, booster pumps, disinfection facilities, reservoirs, valves, and
SCADA systems and also contain preventative maintenance and emergency response
plans.
6.2.3 Surface Supply Operations at the McKenna Falls Intake Facility
The McKenna Falls Intake Facility provides redundant disinfection facilities and
automated and remote control of the Union River source of supply based upon system
demands, influent source turbidity, and chlorine residual. The dam outlet valve controls
Union River Reservoir releases. The transmission main Twin Lakes control valve
controls flows from McKenna Falls to Reservoir 4. Operations personnel determine daily
how much surface supply is available after downstream flow requirements are met. After
requirements for the distribution system are determined to maintain adequate pressure and
storage, appropriate adjustments are made to provide flow to the distribution system,
store water in the Union River Reservoir, or divert excess water to Twin Lakes.
Turbidity of the Main Stem, West Branch of the Union River, and the system intake is
continuously monitored. During high turbidity events, the source of high turbidity is
excluded from entry into the transmission system. High turbidity will also trigger a
remote alarm at the Water Operations Center, which results in an automatic shutdown of
water into the transmission main if the intake turbidity stays above a predetermined level
for a set period of time.
Operations Program
6-5
2005 Bremerton Water System Plan
The disinfection system provides redundant disinfection and automatic system shutdown
and standby power. A flow-paced chlorination system is used to maintain the desired
chlorine residual. If the residual drops below a preset value for a set period of time, the
control valve at Twin Lakes will close, excluding the water from the transmission system.
A remote alarm is then sent to the Operations Center. A generator supplies automatic
standby power to motorized gates, valves, chlorinators, water quality analyzers, and
telemetry systems.
6.2.4 Groundwater Supply Wells
Groundwater supply wells are disinfected (with the exception of Well 19) and are
typically used to supplement the McKenna Falls surface water supply as described below:
· All Anderson Creek Wells (lR, 2R, 3, 6R, 7, and 8) pump to the aeration basin at
Pump Station 2 where their supply is disinfected with chlorine.
· Manette Wells 9, 13, 14, and 21 are generally located along South Central Valley
Road in East Bremerton. These wells have the following methods of operation:
Well 9 can be automatically controlled by the level of Reservoirs 17 and 20. It is
generally operated in Hand Mode because of sand production on start up.
Well 13 is automatically controlled by the level of Reservoirs 17 and 20. During
winter months it typically would be set to follow Pump Station 16.
- Well 14 can be automatically controlled by the level of Reservoir 16. It is usually
run in Hand Mode to optimize production to the East 240 Zone.
· Gorst Area Wells, Wells 15, 17, 18, 19, and 20 are located in the Twin Lakes and
Gold Mountain Golf Course area of West Bremerton. All wells have the following
operational characteristics:
- Wells 15, 18, and 19 are automatically controlled by the level in Reservoir 10
serving the West 517 Zone.
Wells 17 and 20 are automatically controlled based on Reservoir 4 level or Hand
Mode operation and pumped into the McKenna Falls transmission main.
6.2.5 Storage Reservoirs
The Bremerton Main System contains 16 finished water storage reservoirs throughout the
distribution system that are detailed in Section 5, Eight of the reservoirs are located in
West Bremerton, and nine are located in East Bremerton. Two additional reservoirs are
located in the West 517 Zone system. Remote level indications and alarms are transmitted
to the Water Operations Center on Olympus Drive. All reservoirs have telemetry
providing infoTInation on levels, signaling operation to appropriate pump stations, and
sending high, low, power outage, and communication failure alarms. Reservoir
information is detailed in Section 5.7.
Operations Program
6-6
2005 Bremerton Water System Plan
6.2.6 Pump Stations
Pump station modes of operation are summarized in Section 5.
6.2.7 Telemetry and Controls
The City of Bremerton utilizes a SCADA system to monitor and control the water supply
and distribution system with a central computer and two redundant master telemetry units
(MTUs). The system facilities utilize either remote telemetry units (RTUs) or
programmable logic controllers (PLCs) to transfer data and signals.
The computer system was first installed in 1992 to begin replacing the older tone telemetry
panel system when the McKenna surface water system information was transferred to the
SCADA system. Later, the system was upgraded to include automatic alarming, paging,
remote accessing, and transfer of communications from telephone to the more economical
radio system. This upgrade is scheduled for completion in 2006.
6.2.8 Preventive Maintenance Program
Preventive maintenance for the Water Resources Division is tracked and scheduled
utilizing maintenance management software (MMS) for the supplies, reservoirs, pump
stations, hydrants, valves, and pipelines. Equipment information includes identification
number, description, location, manufacturer, model and serial numbers, cost, startup date,
and recommended spare parts.
Programmed standard and site-specific preventive maintenance (PM) procedures and time
intervals for each facility and piece of equipment are also entered into the MMS program.
A PM Due Report lists preventive maintenance tasks that should be completed based
upon the last date of service and specified service interval. The PM Due Report can be
requested for any future date and shows all work to be completed before that date.
The MMS will also forecast the number and type of hours needed to complete the
preventive maintenance program for the specified period. Costs can be calculated based
upon hours, materials, and parts.
6.2.9 Equipment, Supplies, and Chemical Inventory
In addition to maintenance functions, the MMS includes a place for a record containing
the name, address, telephone number, and contact for suppliers, including chemical
suppliers.

provides annual mandatory training along with annual updates of the Material Safety Data
Sheets (MSDS).
The primary chemical utilized in the water supply system is chlorine for disinfection.
Gas chlorine in excess of 1,500 pounds is listed as regulated under the Clean Air Act Risk
Management Plan Rule (RMP) and OHSA's Process Safety Management (PSM). In
1999 Bremerton complied with the requirements of the RMP and PSM. Chlorine is

stored and utilized according to the RMP at McKenna Falls, Anderson Creek, and Wells
15, 17, 18, and 20. Wells 9, 13, and 14 use a 12 percent sodium hypochlorite solution for
disinfection.
The other chemical used in large quantities is 50 percent sodium hydroxide (NaOH) used
to raise pH at the entry to Reservoir 4 to minimize corrosion of customer plumbing for
lead and copper. The NaOH is stored in two 4,000-gallon tanks inside the Corrosion
Control Facility. A separate Operations and Maintenance Manual details operations for
this site.
SARA Title III, Community Right to Know, Tier Two Emergency and Hazardous
Chemical Inventory forms have been completed for each of these sites, and annual reports
are sent to the state, Kitsap County Department of Emergency Management, and
Bremerton Fire Department.
6.2.10 Fluoridation
In 1997, following a public hearings process, the Bremerton City Council voted to
implement water fluoridation as soon as practical. The Water Utility began fluoridation
system design and construction concurrent with the corrosion control treatment design
and construction. Both systems were liquid chemical feed designs, allowing them to be
housed together at Reservoir 4. However, due to considerable negative public response to
the decision, the City Council agreed to re-evaluate and placed the issue on the February
1999 ballot following a citizen petition. Bremerton residents voted down fluoridation.
At the time of the public vote, the fluoridation tank and equipment were in place but not
yet in use. The 6,000 gallon solution tank remains in place, but all the other fluoridation
components have been removed and surplused.
6.3 Water Quality Control and Monitoring
6.3.1 Source Water Quality Protection
Several programs ensure that high water quality is maintained at the source. The
Watershed Control Plan is required by the SWTR and contains the procedures the City
implements to protect the water quality in the Union River watershed. The Wellhead
Protection Plan contains the procedures the City implements to safeguard the water
quality in each of the City's production wells. The recent updates of both the City of
Bremerton and the Kitsap County Critical Areas Ordinances provide further protection of
drinking water sources.
6.3.2 Routine Procedures

6.3.3 State Reporting
The Water Resources Division is responsible for preparing the following reports for the
Washington State Department of Health:
· Monthly state report on CTs, bacterial sampling, and other requirements
· Quarterly monitoring for disinfectants and disinfection by-products
· Semi-annual report of monitoring for the Lead and Copper Rule
· Annual submittal of the Water Facilities Inventory Form
· Annual report for the Surface Water Treatment Rule
6.3.4 Treatment and Monitoring Violation Procedures
The Utility has established procedures in conformance with public notification
regulations for cases when the system violates a primary water quality standard or fails to
meet treatment, monitoring, and analytical testing requirements. Public notices must
provide a clear explanation of the violation, adverse health effects, remedial action being
taken, and steps the consumer should take to minimize risk. Notices are to be distributed
by newspaper notice, direct mail, or hand delivery within specific time frames depending
on the nature of the violation. If the violation is for acute coliform, nitrate, waterborne
disease outbreak, or other acute violation determined by the department, broadcast media
announcements are required within 24 hours of the violation.
All public notifications need to be closely coordinated with DOH and the Bremerton-
Kitsap County Health District. The Utility has a standard boil water notice to be used in
such an emergency.
6.4 Valve Maintenance
The goal of the water main valve maintenance program is to locate and ensure proper operation
of all the valves in the Bremerton distribution system. Approximately 5,700 isolation valves are
in the distribution system. The Valve Maintenance Program Manual contains the proper
procedures for valve maintenance.
6.5 Hydrant Maintenance
The goal of the fire hydrant maintenance program is to ensure adequate fireflow can be delivered
and hydrant operation can be ensured for fire protection purposes. Approximately 1,600 hydrants
exist within the distribution system. The Hydrant Program Manual contains the proper
nroceduresfor hJvdrant maintenance.
r .
6.6 Flushing Program
The goal of the water main flushing program is to maintain water quality and clarity in the
Bremerton distribution system by removing sediment and mineral buildup on a regularly
scheduled basis. The Bremerton Water Utility Flushing Program Manual contains the proper
procedures for flushing. Generally, each side of the water system is flushed every other year.
Operations Program
6-9
2005 Bremerton Water System Plan
The west side of the Port Washington Narrows is flushed one year, and the east side is flushed
the next. The West 517 Zone system is flushed annually.
6.7 Customer Response and Education Program
Bremerton Public Works and Utilities has a customer response program to promptly and
effectively address the public's questions and concerns on broken mains, low pressure,
discolored water, and other water system issues. A dedicated phone number (473-5920) is used
as the Customer Response Line. A field technician assigned to the Customer Response position
makes customer contact within two to four hours of the call and assesses the initial situation to
provide accurate information to the proper division through a customer response work request.
Customer response activities are logged into a database. Information on customer water quality
concerns and questions are required to be submitted in the monthly report.
In 1999 the requirements for the Consumer Confidence Report took effect, and the Utility's
"Annual Water Quality Report" (Appendix) has been sent annually to all customers. This
opportunity is also used to encourage customers to call the Customer Response Line with
questions and concerns about their water. The Utility has prepared brochures and fact sheets to
give customers regarding emergency preparedness, discolored water, chlorine taste, cross-
connection control, indoor and outdoor water conservation, and leak detection.
In addition to the activities listed above, the Utility is involved in several other customer outreach
activities such as:
· Water Festival for fourth-graders in March
· Kitsap Home and Garden Show in March
· Earth Day Events in April
· National Drinking Water Week activities in May
· National Public Works Week in May
· Kid's Day at the Fairgrounds in June
· Water Purveyors of Kitsap Fair Booth in August
· Washington Water Weeks activities in September
6.8 Cross-Connection Control Program
Cross connections are situations where the drinking water system is connected to some other
vessel or system containing anything other than drinking water.. Such connections have the
potential to allow backflow into the drinking water system and are considered to be cross
connections. Wbere no such potential exists, there is no cross-connection.. The drinking water
system routinely supplies water into contaminated systems, such as commercial sites, and the
contaminated mixtures that result must always be prevented from flowing back to the drinking

Operations Program
6-10
2005 Bremerton Water System Plan
Connections to non-drinking water systems can often be avoided entirely by building an air gap.
A typical kitchen sink is a good example of an air gap. The faucet is mounted above the basin,
and the potential for backflow is eliminated. Where air gaps are not possible, a variety of
mechanical devices are employed to eliminate the possibility of backflow. The most common
components of backflow prevention devices are check valves. However, other mechanisms are
also employed, and a wide variety of designs are applied as circumstances require. These devices
are typically redundant by design. For example, a double check valve assembly includes two
valves. If one leaks the other will still provide the needed protection until periodic inspection and
maintenance correct the problem.
New development and redevelopment of properties served by the drinking water system have the
potential to create new cross connections. The backflow prevention devices require inspections
and maintenance. Cross-Connection Control Programs (CCP) address these and other issues.
CCPs are required by Federal, 'State, and local laws. At the Federal level, the SDW A governs
public health related issues associated with water supplies, including the control of cross-
connections. State of Washington drinking water regulations, administered by DOH, are
contained in WAC 246-290-490. Section 490 requires protection of public water systems from
contamination via cross connections. The Code provides ten minimum requirements (elements)
for a CCP, described below. One of these is in regard to establishing the authority to conduct
and enforce the program.
The full picture of cross-connection management is complex and includes building and plumbing
codes, the local or regional health department, private certified backflow-prevention assembly
testers, national organizations and institutions, and others. How Bremerton's program relies on
or coordinates with these other entities is discussed below.
Bremerton has established a CCP to meet requirements in WAC 246-290-490. DOH administers
and enforces this section, which governs activities throughout the public water system up to the
service connections (meters) of individual customers. The Bremerton Department of Community
Development (DCD) and Bremerton's lead Cross-Connection Control Specialist (CCS) enforce
the uniform plumbing code regarding cross connections within individual premises. The CCP
lead coordinates with DCD and the DOH, sharing information as appropriate to contribute to the
public effort to prevent contamination of drinking water via cross connections.
This section has been developed to describe the City's CCP and includes:
· An overview of the CCP
· A description of each ofthe ten program elements required by WAC 246-290-490
· Reference to associated forms, submittals, and other items as necessary

increasingly stringent regulations. The program is overseen by the Public Works and Utilities
Department. The Utilities Operations Division is the lead in implementing the program and is
assisted by and shares in the resources of other divisions, including the Engineering and Water
Resources Divisions.
Operations Program
6-11
2005 Bremerton Water System Plan
The program tracks an inventory of over 1,500 backflow prevention devices and typically
reviews more than 150 project submittals each year. The Department has five certified Cross-
Connection Control Specialists and two certified backflow assembly testers on staff.
The program relies on both premise isolation and in-premise isolation to control cross
connections. Within the City, the backflow prevention devices the program is concerned with
are located at both the service connection, where drinking water first flows from the public
distribution system into the private "on-site" plumbing, and at fixtures inside the premises that
may pose potential hazards. The City does not regulate in-premise isolation for customers outside
the city limits.
6.8.1 Cross-Connection Control Program Elements
WAC 246-290-490 requires CCPs to include at minimum, 10 elements to be considered
acceptable. This section describes each of the minimum elements required by
Washington State law and Bremerton's implementation of these elements.
Element 1 - Legal Authority for Cross-Connection Control Program
This element requires awater purveyor adopt a local ordinance, resolution, code, bylaw,
or other written instrument that:
· Establishes the purveyor's legal authority to implement a CCP;
· Describes the operating policies and technical provisions of the CCP; and
· Presents the corrective actj(lns to be used to ensure customers' compliance with the
CCP.
Bremerton 's Status
The City has an established CCP as authorized by federal and state law. Title 15.02.170
of the Bremerton Municipal Code adopts by reference the State of Washington cross-
connection control regulations and subsequent revisions.
The City also issued a Departmental Policies and Procedures document in May 2001 that
established compliance with all of WAC 246-290-490 as the minimum standard for the
scope and goals of the CCP. This procedure establishes two widely used documents as
the primary guiding resources for program details. These documents are:
1. The Cross Connection Control, Accepted Procedure and Practice Manual (most
current edition), published by the Northwest Section of the American Water Works
Association. (Hereafter referred to as the Northwest SectionManual.)
2. The Manual of Cross-Connection Control (most current edition), published by the
Foundation for Cross-Connection Control and Hydraulic Research at the University of
Southern Cali f0111i a. (Hereafter reft;lTi~d to as the use Manual.)
Operations Program
6-12
2005 Bremerton Water System Plan
Element 2 - Evaluation of New and Existing Service Connections
This element requires each purveyor to develop and implement procedures and schedules
for evaluating new and existing service connections. These evaluations must assess the
degree of hazard posed by connections to the purveyor's system, and property owners
must be notified of the results in a timely manner. Once an initial evaluation has been
conducted, service connections must be re-evaluated periodically according to a schedule
acceptable to DOH and whenever there is a change in use of the premises.
Bremerton 's Status
Bremerton's Cross-Connection Control Specialists (CCS) evaluate the degree of hazard
for all new service connections when connections are re-instated after a period of non-use
and whenever a change arises in use of a property served. The City's accounting
department aids in tracking these events and actively provides information to the CCS.
All building permit applications are routed through the CCS, and all divisions of the
Public Works and Utilities Department are made aware of the need to relay information
related to cross-connection control to the specialist. The City has developed a cross-
connection control survey form that facilitates evaluations and record keeping. The
City's plumbing permit process requires that an application for a service connection be
made before the plumbing permit is issued. Utilities Operation Division staff also
perform reconnaissance to find otherwise unreported cross connections, such as home-
owner installed irrigation systems. The CCP database is also used to track new
installations and any pending improvements. Late notices and visits to the premise are
used to ensure resolution. The City reserves the right to install or repair assemblies at the
premise boundary and bill the customer or terminate service if the customer remains
unresponsl ve.
The County's Dcn provides information when solicited, and the Kitsap County Health
District shares information they discover as appropriate. The information from all these
sources is directed to the CCS in order to provide a single-point comprehensive view of
potential cross connections to the Bremerton drinking water system.
All degree of hazard evaluations are conducted by a certified CCS employed by the City.
Procedures include a site visit, interview with the owner or operator of the premises (or
their representative), evaluation of the condition of existing backflow prevention devices,
and consideration of the types of premises and related activities recognized as high health
hazards in Table 9 of WAC 246-290-490. These evaluations also take into consideration
relative probability of occurrence and other variables described in the Northwest Section
and USC Manuals. All evaluations are documented and filed, and copies are provided to
the owner of the premises within 30 days of the site visit.
More information on recordkeeping and responses to the results of hazard evaluations is
discussed under other program elements below.
Operations Program
6-13
2005 Bremerton Water System Plan
Element 3 - Cross-Connection Elimination, Control, and Prevention
This element requires cross connections to be eliminated whenever possible or, where
they cannot be eliminated, that approved backflow assemblies commensurate with the
degree of hazard be properly installed.
Bremerton 's Status
Bremerton fulfills the requirements of this program element by the same basic approach
employed to evaluate the degree of hazard (described above). This is primarily through
the project/plan review process, other methods of collecting information, and
enforcement of regulation and policy. Certain types of potential cross connections are
prohibited, and air gaps are required wherever they are plausible. Where air gaps are not
plausible, the results of the hazard evaluation and the following requirements and
guidelines are used to determine the type of backflow prevention device required and the
approved models available to choose from:
· Tables 8 and 9 ofW AC 246-290-490
· DOH Publication 331-137, Backjlow Prevention Assemblies Approved for
Installation in Washington State, Revised February 2005
· The Northwest Section Manual
. The USC Manual
Element 4 - Cross-Connection Control Personnel
This element requires the purveyor to ensure that personnel are provided to develop and
implement the CCP. At least one must be a certified CCS.
Bremerton 's Status
Bremerton's staff holds all CCP-related required certifications, and the City funds
training commensurate with current and future program needs. The Utility Operations
Manager and the lead CCS are both CCS certified. The CCS lead and other employees
are backflow assembly testers (BATs).
The CCS lead or persons under his direction implement, update, and otherwise manage
the CCP. Contributions to the program come from staff in the administrative,
engineering, and water resources divisions. Members of the Utility crews are also aware
of and support the program.
Element 5 - Backflow PreventerInspection and Testing
The water purveyor must ensure that approved backflow preventers are inspected and
tested for proper operation in accordance with WAC 246-290-490. Specific requirements
related to inspection and testing and Bremerton's methods for complying with them
include:
· Confirming the type of back flow preventer is commensurate with the assessed degree

Bremerton 's Status
Bremerton ensures scheduled tests, and the results of testing indicate the correct type
of device is installed for the subject premise or application. The degree of hazard
assessment itself is performed separately and discussed above.
· Confirming the installation/configuration is correct and the make and model of the
device (where applicable) is on the approved list.
Bremerton 's Status
These activities are associated with the actual testing of devices and are conducted
primarily by private, certified BATs. Each new assembly is verified after it is
installed. If the assembly is replaced, then the replacement is verified when test
results are entered. Certified Bremerton personnel also evaluate the devices
(including air gaps) by these criteria whenever they inspect.
· Conducting inspection and testing:
When installed
- Annually thereafter (with certain specific exceptions)
- After any backjlow incident
- After repair, relocation, etc.
By certified BA Ts
- By acceptable methods (e.g., as outlined in the use Manual)
Bremerton 's Status
Bremerton assures these elements by following the project/plan review process
mentioned above; keeping an inventory of all devices; scheduling, requiring and
reviewing the tests; and requiring all testing be completed by certified BATs.
· Effectively documenting inspection and testing results.
Bremerton 's Status
Bremerton requires BATs to report their results on a "Backflow Assembly Test
Report" that prompts for all essential information and facilitates record keeping and
use of data;
· Requiring and enforcing corrective actions whenever the backflow preventer IS
discovered to be inappropriate, incorrectly installed, or in need of repair.
Bremerton's Status
Bremerton seeks cooperative solutions with all customers but has the authority to
discontinue water service until required improvements are complete. Bremerton
Operations Program
6-15
2005 Bremerton Water System Plan
exercises this authority according to risk. If emergency conditions or immediate
health hazards exist, service may be terminated immediately. In circumstances where
the degree of hazard is low, Bremerton requires improvements to be made as soon as
possible but allows the customer up to 90 days to complete improvements.
Enforcement actions are initiated by the CCS, who informs the Director of Public
Works and Utilities and the building department, who in turn may contribute to the
process. Every corrective action item is tracked through resolution and facilitated by
letters and phone conversations as necessary.
Element 6 - Quality Control Assurance Program
The water purveyor is required to develop and implement a quality control assurance
program for the testing of backflow prevention assemblies. Certified BATs are required
to take steps to control the quality and reliability of their work, and purveyors, such as
Bremerton, are required to assure they do so. The program must include at a minimum
documentation of tester certification and test kit calibration, standard requirements for the
contents of test reports, and requirements for submitting completed test reports in a timely
manner.
Bremerton 's Status
Bremerton posts a list of approved testers who request to be on the list on the City's
website (www.ci.bremerton.wa.us) and updates it periodically as a public service.
Bremerton keeps copies of up-to-date certifications and test kit calibration results on file
for the BATs who are on the published list. Any Washington State certified BAT may
test assemblies in Bremerton's service area, but those who are not on the list must submit
copies of current certification and test kit calibration with each report. The City notifies
property owners of the need for testing about 30 days before the due date. If no report is
received within that period, the property owner is notified through a late notice,
establishing a deadline of 10 days after the late notification. If the property owner does
not comply, the CCS follows up with a site visit or phone call. Problematic results are
followed up with a phone call to the tester and possible inspection of the assembly in
question.
Element 7 - Backflow Incident Response
The water purveyor is required to develop and implement procedures for responding to
backflow incidents.
Bremerton's Status
The BremertonDepartment of Public Works and Utilities is prepared to respond to a wide
variety of incidents related to the drinking water system. Evidence of poor water quality
or possible contamination is resolved on a case-by-case basis. The methods Bremerton
would employ in such cases are standard in the industry and include (but are not
necessarily limited to) isolation/termination of source, flushing, containment by main
isolation, water quality testing, customer notification, and coordination with other
departments and agencies. Bremerton also has an Emergency Response Plan that would
Operations Program
6-16
2005 Bremerton Water System Plan
apply in some instances of contamination due to cross connection.
Element 8 - Consumer Education
This element requires a water purveyor to educate consumers about cross connections.
The WAC recognizes that purveyors must have a broader public education program and
requires information on cross connections be a part of it. Examples of educational
materials include bill inserts, pamphlet distribution, and consumer confidence reports.
Bremerton 's Status
Information on cross connections is included in Bremerton's annual consumer confidence
report. New customers receive brochures, and the City has conducted public outreach at
events such as fairs. Brochures are also available in the lobby of the Public Works and
Utilities Department, and information is mailed to any customer who inquires about cross
connections or related issues. Whenever a premise is inspected, the owner of the premise
receives a brochure and other information as appropriate.
Element 9 - Record Keeping
This element requires purveyors to keep up-to-date records documenting cross connection
efforts and information, including:
. A master list of service connections where backflow preventers are installed, as well
as the assessed hazard level for the premises and the type (category) of backflow
preventer( s) required for each;
. Detailed information on each individual air gap, backflow assembly, and atmospheric
vacuum breaker, including (as applicable):
Location
Date of installation
History of inspections with results and inspector's name
Product specific data, including model, size and serial number
. CCP summary reports and backflow incident reports per WAC 246-290-490.
Bremerton 's Status
Bremerton has a record keeping system designed to be responsive to these codified
requirements and includes all the necessary types of information. The effort to make it
complete and keep it up-to-date is ongoing. Air gaps and backflow assemblies are being
incorporated into the data base as they are being installed and discovered. Bremerton also
submits an annual CCP report to DOH.
Element 10 - Reclaimed Water
Under this element, purveyors that distribute or have facilities that receive reclaimed
water within their service area must abide by additional cross
ro."'.............. ,"",ro.f~ r.......... ........--........+....,.." 1

requirements imposed by the DOH under a permit issued in accordance with Chapter
90.46 RCW (reclaimed water use permits).
Bremerton's Status
Currently, one private facility receives reclaimed water directly from Bremerton's
wastewater treatment plant through pipelines not connected to the drinking water
distribution system. These facilities, however, are also served by the drinking water
system (via separate connection). Bremerton Public Works and Utilities coordinates the
cross-connection control provisions of the reclaimed water use permit with the CCP
associated with purveying drinking water. The CCP data base includes information on
which premises receive reclaimed water, and the CCS considers this information during
evaluations of degree of hazard.
6.9 Safety Program
The Department of Public Works & Utilities produced a Departmental Safety Manual as an
addition to the City's Accident Prevention Program. Although the City's Program is
comprehensive in requirements for Confined Space Entry, Hazardous Material Communications,
Job Hazard Analysis, Motor Vehicles, etc., the Departmental Manual takes into consideration
those tasks unique to Public Works and Utilities Operations and expands safety requirements
accordingly. Some specifics of the Departmental Manual not covered by the City's Program are:
. Heavy equipment operation
. Hazardous material/chemical handling
· Hazard control
. Specific responsibilities of both supervisors and employees
. Tools and equipment
. Job site safety
· Vehicles:
Driver qualifications
Accidents and accidentinvestigations
Excavating and trenching
The Departmental Safety Manual is continuously reviewed by the Department Safety Officer and
updated as necessary.

Tables 1-4 and 1-5 summarize operation and maintenance responsibilities that have been
assumed by the City of Bremerton for contract customers.
6.13 Emergency Response Program
6.13.1 Standby Personnel List
The Bremerton Water Utility has Telemetry Alarm Standby and Utility Operations
Standby Schedules listing primary and secondary water utility personnel for both
telemetry alarms and distribution problems. Tne list specifies the weeks assigned to
standby, names, phone numbers, pager numbers, and addresses. Advisory staff is listed
for standby personnel to contact depending upon the nature of the problem. This standby
list is used by the CENCOM 911 Center when an after-hours emergency call through the
911 system or from the SCADA system is received.
6.13.2 Vulnerability Analysis and Emergency Planning
The Public Health Security and Bioterrorism Preparedness and Response Act of2002
requires community water systems .to conduct vulnerability assessments (VA) under the
authority of the U.S. Environmental Protection Agency. The law also requires water
utilities to develop a new Emergency Response Plan (ERP) or enhance an existing ERP
within six months of completing the V"I'1~.
The VA process evaluates susceptibility to potential threats and identifies corrective
actions that can reduce or mitigate the risk of serious consequences from adversarial
actions such as vandalism, insider sabotage, or terrorist attack. This assessment takes into
Operations Program
6-19
2005 Bremerton Water System Plan
account the vulnerability of the water supply, transmission, treatment, and distribution
systems. It also considers risks posed to the surrounding community related to attacks on
the water system. An effective V A provides a prioritized plan for security upgrades,
modifications to operational procedures, and policy changes to mitigate the risks and
vulnerabilities to the Utility's critical assets. The V A provides a framework for
developing risk reduction options and associated costs.
The Bremerton Water Utility used the RAM-W method for developing a VA. This
process was detailed, required extensive documentation, and consisted of several steps
which complied with the following six basic elements required for the VA: .
1. Characterization of the water system, including its mission
2. Identification and prioritization of adverse consequences to avoid
3. Determination of critical assets
4. Assessment of the likelihood of malevolent acts from adversaries
5. Evaluation of existing countermeasures
6. Analysis of current risk and development of a prioritized plan for risk reduction
The V A was conducted in-house by a team of City employees representing diverse areas
of water system operations and security expertise. In addition, Bremerton hired a firm
with security expertise to evaluate existing security measures and recommend future
security improvements. EP A has identified eight core elements common to an ERP that
form the basis for responding to any major event:
1. System specific information
2. Water system roles and responsibilities
3. Communication procedures: Who, What, and When
4. Personnel safety
5. Identification of alternate water sources
6. Replacement equipment and chemical supplies
7. Property protection
8. Water sampling and monitoring
The purpose of the ERP is to identify planning and specific response actions to be taken
during an emergency that \yill maintain quantity and quality of water, protect employees,
minimize disruption to the public, and preserve property. This document addresses water
emergencies that will behandled prinlarilyby the Utility as well as the Utility's support
and cooperation with other agencies during large-scale emergencies.
Casad Dam and Reservoir 4 are regulated by the Department of Ecology Dam Safety
Section. The Utility has specific plans (Bremerton Dam Safety Emergency Action Plan and
the Reservoir 4 O&M Plan/Emergency Action Plan) addressing dam safety. The Utility
also has a specific emergency response plan for chlorine handling at the McKenna Falls
Intake Facility as required by the RMP and PSM regulations described earlier.
Operations Program
6-20
2005 Bremerton Water System Plan
System failure prevention is accomplished by modern system design, watershed control and
management, backup power supplies at critical locations, scheduled maintenance and
replacement, water quality sampling and testing, remote system monitoring, routine facility
inspection, automatic and manual control redundancy, and Utility personnel safety and
operational training.
Although the system design criteria include consideration of equalizing, standby or
emergency and fire storage, there is always the remote possibility of a combination of
events such as an earthquake causing significant system damage along with a large
numbers of fires. Additionally, any facility could be out of service for a short period of
time for planned maintenance and for a potentially longer period of time for unplanned
maintenance.
The most likely vulnerability for the water system is a large earthquake, as the probability
of a large earthquake in the region is high. In the past five years, several earthquakes of
magnitude up to 6.8 (February 2001 Benioff earthquake) have occurred. In 1997 the Utility
conducted an Earthquake Vulnerability Analysis, which identified projects and budget
estimates to upgrade transmission lines, reservoirs, and other system components to better
withstand earthquakes. In 1996 several City and Utility staff members attended the FEMA
earthquake simulation training in Maryland.. and will attend another FEMA training
scheduled for 2006.
6.14 Operation and Maintenance Improvements
The following improvements to the operation and maintenance of the Bremerton water system
are planned in the next six years or are already underway:
. Continuation of the security upgrades identified in the VA
. Design of the ultraviolet system for compliance with SWTR regulations
fit Improvements to disinfection and evaluation of chlorine gas alternatives
. Upgrade of the SCADA to a fully PLC-based system
Capital improvements are detailed in Chapter 9.

Section 7
Performance and Design Criteria
7.1 System Demands
Bremerton's average day demand (ADD) for 2004 was 7.7 MGD. This includes contract
distribution of water to other districts and to the Puget Sound Naval Shipyard (PSNS). The
average water use in the Bremerton Water Service area is approximately 183 gallons per day per
equivalent residential unit (ERU).
The highest maximum daily demand (MDD) between 1999 and 2004 was approximately 15
MGD. The ratio of this demand to the average daily demand is approximately 1.8. For purposes
of analyzing the water system, the ADD will be multiplied by 2.0 to determine MDD, and the
following assumptions will be used:
. Residential Average Day Demand = 200 gallons per day per ERU
. Residential Maximum Day Demand = 400 gallons per day per Single Family Unit
· Peak Hourly Demand Multiplier =1.74 (PHD:MDD)
7.2 Pipe Sizing Parameters
Water system pipelines are to be designed to limit velocities to 8 feet per second (fps) under peak
hourly demand flow conditions. During normal average day demand flow conditions, the
velocities should be limited to 5 fps. Pipelines must also be sized to pass fire flows with
velocities less than 10 fps and without residual pressures dropping below 20 psi. The minimum
pipe size for water lines is 6 inches for looped portions of water mains and 8 inches for dead
ends. Also, fire hydrant leads less than 50 feet in length shall be at least 6 inches in diameter.
7.3 Fire Flow Standards
A major function of the water supply and distribution system is to meet fire flow demands. This
section summarizes the fire flow requirements applicable to the Bremerton water system, which
serves areas both inside the city limits and in unincorporated Kitsap County. Bremerton serves
water to residential and commercial structures in three fire districts:
. City of Bremerton (within city limits)
· Central Kitsap Fire and Rescue (north of the city limits)
. South KitsapFireand Rescue District #7 (south ofthe city limits and Port of Bremerton)
The Bremerton Fire Department adopted by ordinance Appendices Band C of the International
Fire Code (IFC), listed in Table BI05.1 in the IFC. The Kitsap County Fire Marshal's office
adopted a separate fire flow and hydrant placement, Ordinance 323(A)-2005, amending the IFC.
Water System Description
7-1
2005 Bremerton Water System Plan
The fire flow requirement for specific projects IS dependent on many factors, including the
following:
. Size of the structure( s)
. Location of the project
· Type of construction materials
· Number of stories
· Building fire protection systems (sprinklers, automatic fire doors, etc.)
. Proximity of adjacent structures
· Type of building occupancy (storage of flammable materials, etc.)
For purposes of this water system plan, minimum fire flows to be provided by the Bremerton
water system have been identified as:
Residential
Commercial
1,000 gpm for 2 hours
I ,500gpm for 2 hours
Fire flows required by the IFC are considered minimums for new construction. When evaluating
new construction, Bremerton Public Works and Utilities Department personnel shall determine
the ability of the water system to meet fire flow requirements at that location with a minimum of
20 psi residual pressure throughout the distribution system. If the water system cannot provide
the required fire flow for the specific project, the developer is required to revise building
construction and/or make the necessary improvements to the distribution system to meet the
project's fire flow requirements as established by the Fire Marshal.
The Washington Survey and Rating Bureau is a non-profit organization funded by subscribing
property insurance companies in accordance with the Washington State Insurance Code. They
are tasked with rating the fire fighting and protection abilities for municipalities. This rating is
then used by insurance companies for setting rates. The water system's capability is 39 percent
of the total rating score. Bremerton's last survey was completed in 1997, and the water system
ranked as Class II, an excellent rating.
The hydraulic analysis of fire flows for the Bremerton water system is discussed in Section 8, fire
flow and storage requirements. Bremerton analyzed storage capacity without nesting fire
suppression and emergency standby storage.
7.4 Backup Supply/Systems
It is highly desirable to have as much redundancy as economically feasible within the water
system. This is particularly true with respect to meeting fire flow requirements. Frequently, fires
and system disruption can occur as a result of natural disasters such as earthquakes. Power
outages, regardless of cause, can severely impact fire fighting efforts if a pump station is affected,
or if fire fighting water is supplied from a nearby well. For these reasons, the City of Bremerton
employs the following system redundancy measures:
Water System Description
7-2
2005 Bremerton Water System Plan
. Redundant components in the surface supply disinfection facilities.
. Multiple wells in each of several wellfields located in different aquifers.
. Multiple pumps (two minimum) in all but one pump station (PS14 has only one'pump but has
a backup in PS 11).
. Multiple transmission mains.
. Isolation valves at critical connections and spaced along major transmission mains so that
damaged portions of main can be easily isolated and repaired.
. Multiple storage reservoirs for each major pressure zone except the West 650 Zone. This
zone has one reservoir but currently has excess capacity for that zone.
. A looped distribution piping system.
. Multiple water mains serving large major customers such as the Navy and Harrison Hospital.
. An adequate number and location of fire hydrants.
. Adequate storage of water in reservoirs to supply fire flows.
. A vailabilityofback-up emergency power for wellfields, pump stations, and booster pump
stations (depending on available storage) and transfer switches for generator connection.
. A 150 kW trailer-mounted generator to move to needed locations.
. Telemetry systems with alarms for critical components in the system and automatic call-out
of operations personnel.
The City encourages future project development to be designed and constructed using fireproof
materials, partitions, and fire sprinklers to minimize fire protection demands. A specific analysis
of the water system is performed for each new development project to determine fire flow
requirements and water system improvements required to provide adequate fire protection.
7.5 System Design Standards
This section presents a summary of the general design criteria for the distribution system. Two
standards documents, "The City of Bremerton Utilities Development and Construction
Standards" and the "Standards for Work in the Rights of Way" are developed by the Department
of Public Works and Utilities. Minimum design standards are also described in the Kitsap
County Coordinated Water System Plan.
This section presents some of the criteria used to analyze the existing and proposed system to
identify any deficiencies that may exist. The analysis of the system will be discussed in more
detail in Section 8.
7.5.1 General
All new developments connecting to the system shall be designed by a civil engineer
registered with the State of Washington.
Water System Description
7-3
2005 Bremerton Water System Plan
The City of Bremerton retains the right to review and approve the design and inspect all
new facilities during construction and prior to being placed in service.
Connections to the existing water system must be in accordance with City of Bremerton
Utility standards.
Service lines shall be installed so each residential, commercial, and industrial structure
has a separate meter. If approved by the City, domestic water consumption may be
measured by a master meter for service to a complex under single ownership and where
water utility line separation is impractical.
7.5.2 Pipelines
Water lines are to be constructed within city or county right-of-ways or utility easements.
These easements should be at least 15 feet wide. Pipelines should be located at least 5
feet inside the boundary of all easements and right-of-ways.
Minimum pipe sizes and velocities were specified previously in Section 7.2.
All pipelines should be looped where possible.
At a minimum, pipe materials should meet A WW A Standard C 100 for ductile iron pipe
and fittings unless approved by the Utility prior to installation.
Transmission mains should be at least 12-inch diameter and not have any service
connections. Larger diameter mains will be required if the Water Utility determines that
a larger diameter is justified based on the hydraulic analysis.
All water mains should have a minimum cover of 36 inches over the top of the pipe.
Minimum separation distances between water mains and sanitary sewer mains should be
ten feet horizontally when the mains are parallel. Adjustments to these requirements may
be allowed if the proposed adjustments are within the latest guidelines published by the
Washington State Department of Ecology.
A minimum separation distance of five feet horizontally is to be maintained between
water mains and storm sewer systems and the water main shall be a minimum of two feet
above the storm sewer when crossing. Lesser separations will be allowed if it is shown it
is not feasible to locate the water main further away.
All new piping should be pressure tested to a minimum of 150 psi over normal working
pressures (but no less than 225 psi total) for 15 minutes per the requirements of the latest
edition of the WSDOT IAPW A Standard Specifications for the State of Washington.
Water System Description
7-4
2005 Bremerton Water System Plan
7.5.3 Automatic Control Valves - Pressure Regulating, Reducing, and
Relief
Automatic control valves are used to intertie the Utility's pressure zones to utilize stored
water at higher elevations and to lower pressures to acceptable service levels.
These valves will be sized to provide the maximum instantaneous demand or the required
fire flow, whichever is greater.
In some areas where the system line pressures exceed 80 psi, it is recommended that
customers install individual pressure reducing valves on their service lines.
7.5.4 Transmission and Distribution Piping Valves
A sufficient number of valves are installed in the system to allow isolation of the system
for maintenance and repair. As a guideline, valves should be located at all tees and
crosses and have a maximum spacing of 500 feet.
Two-inch minimum air and vacuum release valves should be installed at all high points in
the piping system.
Zone isolation valves should be installed at all zone boundaries. This arrangement could
allow future pressure zone boundary realignment without the need for additional pipe
construction.
7.5.5 Fire Hydrants
Fire hydrants should be 5-1/4 inch or larger. Hydrants should be spaced a maximum of
500 feet apart in residential areas and a maximum of 300 feet apart in multi-family
residential areas, commercial areas, and industrial areas.
Six-inch fire hydrant leads should be no longer than 50 feet. Fire hydrant leads greater
than 50 feet in length shall be 8-inch diameter minimum.
Hydrants should be dry-barrel construction, conforming to A WW A C502, and equipped
with national standard threads or devices.
Fire hydrant type, features, and spacing must be approved by the Utility and fire
protection authorities.
7.5.6 Disinfection and Testing
All new.piping, reservoirs, and appurtenances .must be flushed, disinfected, and tested in
accordance with the standards of DOH, AWWA C600 and DI05, or WSDOT/APWA
Section 7-09.
Water System Description

2005 Bremerton Water System Plan
7.5.7 Cross Connection Control
Where a possibility of contamination of the potable water system exists, appropriate cross
connection control measures must be taken to protect the water system. Refer to
Bremerton Municipal Code Title 15.02.170 and WAC Chapter 248-54-285, Cross
Connection Control, and Section 6.8 of this WSP.
7.5.8 Other Guidance Standards

Section 8
System Analysis
--
8.1 Hydraulic Analysis
8.1.1 Methodology
The City of Bremerton Main and West 517 Zone Systems were analyzed using the
hydraulic modeling software program WaterCAD 7 Service Pack 2 by Bentley, Inc. The
WaterCAD software is a Microsoft Windows-based program that interfaces with
AutoCAD to allow entry of all system properties and displays them on the monitor as an
AutoCAD drawing file. All modeling calculations are performed within the WaterCAD
program, and the AutoCAD program allows the user to display the results in various color
coding schemes depending on the desired appearance.
8.1.2 System Components
The WaterCAD software allows all of the pipes and junction nodes to be entered into one
complete model, which consists of approximately 2,450 pipes and 1,800 junction nodes,
along with pressure reducing stations, reservoirs, wells, and pump stations. The number
of system components in the model is different from the actual number found in the
Bremerton water system, because some operations are simulated differently in the model
than they are in the existing system. All of the system data, such as pipe diameters,
reservoir areas, and node elevations, were entered into the model by the City based on
water system maps. A copy of the model input data and a map showing the node and
pipe numbers are contained in a separate document.
8.1.3 Current System Demand
When the model was originally developed in 1999, the City was divided into 62 separate
meter zones reflecting similar residential and commercial demands throughout the
system. The boundaries of the meter zones were overlaid onto the water model to
establish the number of junction nodes in each zone. Demands Were allocated to the
nodes in each of the meter zones by using residential demands for the entire meter zone
divided by the number of nodes in the model representing that zone.
The model was updated to reflect present day demands in the following manner:
. All the demands in the model except the PSNS demands were summed to determine
the ADD represented by them.
. Actual PSNS demands were inserted into the model at the nodes representing the
three master meters serving the shipyard.
. The demands at the remaining nodes of the Main System were multiplied by a
correction factor to increase the total demand in the model to the current ADD of 7.9
System Analysis

2005 City of Bremerton Water System Plan
MGD.
· A second demand alternative was created for the Main System to provide a current
system-wide MDD of 15.82 mgd.
· A separate demand projection was used for the West 517 Zone System, as all its
future growth is commercial and will rely on the development schedule for the South
Kitsap Industrial Area (SKIA), which has not yet begun, and the possible construction
of a NASCAR Race Track, which is still in the very preliminary planning stages.
Residential demands in the model were assigned a diurnal or daily usage pattern based on
the Washington Department of Ecology (Ecology) diurnal curve. Large commercial
demands were assigned either this diurnal curve or a fixed pattern based on the type of
commercial enterprise and probable water usage pattern.
PSNS demands are assumed to follow a fixed usage pattern. This assumption has been
verified through field measurements where the maximum flow through the meters in a
24-hour period exceeds the minimum flow by only 20 to 30 percent.
All commercial demands included in the model were assigned to the nearest junction
node, except for PSNS. PSNS has a commercial ADD of 2.28 MGD distributed among
three different junction nodes representing the three master meter locations. MDD is
assumed to be 2.0 times ADD, fora current PSNS MDD of 4.56 mgd.
8.1.4 Calibration
The Water Utility performed a number of hydrant flow tests throughout the system to
determine flow, static and residual pressure, and pressure drop in known segments of
pipe. For the calibration analysis, a single "snapshot" (steady-state) simulation was used
to calculate flow throughout the system for a single point in time. This simulation
assumes the system reaches equilibrium with respect to flows instantaneously. The
information from the model run was used to compare the static and residual pressures
associated with the model simulations and each hydrant test to determine the accuracy of
the model. Successful calibration of the static pressure indicates network components are
operating correctly, demand is appropriately allocated, and reservoir levels are correct.
Successful calibration of tlle residual pressure and pressure drop during the hydrant tests
indicates pipe roughness coefficients are set at the appropriate level similar to actual
conditions.
Eight hydrant flow tests covering the full system area were performed in the field and
simulated with the model. Table 8-1 shows the results of each hydrant flow test, along
with the results of the model simulations at each location.

2005 City of Bremerton Water System Plan
The first five locations listed in the table are situated in the east pressure
zones of the City and show reasonable agreement between the hydrant test
results and the model simulation results. The static pressures for each of the
five locations during the simulations are consistently plus or minus
approximately 4 psi from the model, indicating that the reservoirs, pump
stations, and PRV s are operating correctly and that demand is allocated
appropriately. The residual pressures and pressure drops are also reasonably
close to the model simulations, indicating that the roughness coefficients are
close to the actual conditions.
The last three locations listed in the table are found in the west pressure zones of the City,
and the simulation for one does not agree with the test results. The hydrant test
conducted at 2530 Rocky Point gave a static pressure of 70 psi, a residual pressure of 60
psi, and a drop of 10 psi. The model simulation showed agreement with the pressure
drop, but it also showed significantly lower static and residual pressures. This indicates
the system is operating properly, but lower pressures are shown in the model than in the
existing system. Several possible explanations for this difference include reservoir
elevations simulated at a lower level in the model than during the field test or incorrect
elevations for the pressure gages. It was not possible to obtain a better correlation
between field and model values with the available calibration information. The City is
investigating the differences between the field results and the model and will edit the
model as needed.
From this information, it appears the model is reflecting field conditions to a level
adequate for planning purposes. The City is continuing to improve the accuracy of the
model for use in design and fire flow analysis for specific new developments. Calibration
of the model will continue as new field tests occur and the data from the field will be
transferred to the model.
8.1.5 Future System Demand
In six years (by 2011), the ADD for the Main System, excluding potential conservation
savings, is expected to increase to approximately 9.15 MOD, and the MDD is forecasted
to be 18.29 MOD. By the year 2024, the ADD is expected to increase to about 11.91
MOD, and the MDD is forecasted to be 23.83 MOD. Again, both of the ADD demands
are based on population and demand forecasts and the assumption that there would be no
savings due to water conservation strategies. For modeling purposes, use of higher
demands throughout the system provides a more conservative result than using the
demands projected using conservation. All of these future demands were allocated in the
water model by setting the demand for the three PSNSjunction nodes and multiplying the
remaining 2005 demand by a constant value to increase the total demand to the forecasted
amount. The demand for each junction node was then entered into different model
scenarios depending on which forecasted year was being modeled.

2005 City of Bremerton Water System Plan
This assumption does not precisely reflect the projected growth in Bremerton. Growth
will occur at higher rates in selected areas than for the overall city. This allocation of
demands allows a planning level analysis of the water distribution system, with the
understanding that a more detailed model will be used to evaluate specific parts of the
system.
For the West 517 Zone System, future demands are assumed based on planning
documents for SKIA, a commercial development area. Development of SKIA is
dependent on sewer service, which has not been resolved. This industrial area is currently
served by an on-site septic system, which is the current limiting factor to growth.
8.1.6 Modeling Scenarios
The WaterCAD model was constructed with a number of different modeling scenarios to
reflect system demands and piping configurations in years 2005, 2011, and 2024 and
determine the system operation in those years. Table 8-2 shows the scenarios identified
below and lists the overflow and starting elevation for all the reservoirs in the system,
capacity and the status for each pump station and well, and type of simulation performed
(static or extended period).
The following specific scenarios were run:
. Calibration
. Determination of Current CIP Requirements (i.e., improvements needed to mitigate
current distribution system issues)
- Current PHD (existing system)
- Current MDD with Fire Flow (existing system)
- Current PHD (Current CIP)
- Current MDD with Fire Flow (Current CIP)
. Determination of 6-year CIP (i.e., identifY the projects needed by 2011)

2005 City of Bremerton Water System Plan
These simulations will produce a Capital Improvement Program for the next 20 years that
will enable the City to surpass the minimum pressures set by DOH and identify the
improvements required within the next six years.
According to WAC 246-290-230, water systems must be designed to deliver PHD at 30
psi at all points in the distribution system with equalizing storage depleted. The
distribution system must also provide MDD plus the required fire flow at a pressure of at
least 20 psi at all points in the pressure zone with equalizing and fire flow storage
depleted. This analysis was achieved in WaterCAD by completing the following actions:
. In general, the model was run in steady-state mode using two different demand
alternatives, depending on the scenario being studied. To determine if the system met
the PHD (minimum pressures of 30 psi), a steady-state simulation was used with
demands set at the peak hour level. Reservoir levels were set at the levels identified
in Table 8-2 to approximate depletion of the equalizing storage. Reservoir levels
controlled the operation of pumps and wells in the system. If a pump would be called
to operate at the reservoir level used in the analysis, it was in operation during the
simulations.
. For the fire flow analysis, a steady-state simulation was used. Reservoir levels were
set at the point where equalizing and fire flow storage are depleted. This reservoir
elevation corresponds to the condition at the end of the fire event. Reservoir levels
controlled the operation of pumps and wells in the system. A fire flow of 1,000 gpm
was desired at all the residential nodes in the system, and 1,500 gpm was desired at
commercial sites. Selected nodes were simulated with higher flow rates, depending
on their locations with respect to commercial/industrial facilities. More information
on the fire flow simulations is provided below.
The MDD scenarios were run with McKenna Falls Intake contributing no more than 18
MGD to the system.
8.2 System Physical Capacity Analysis
System physical capacity is defined by DOH as the components or facilities (i.e., source,
treatment, storage, transmission, and distribution) that either individually or in combination limit
the number of ERUs that can be served. For Bremerton's system, an ERU equals about 200
gallons per day (ADD). The ERU calculation is described in Section 2.4.3. The overall design
goal of maintaining adequate pressure of at least 30 psi in the distribution system at peak hourly
demand and 20 psi under peak hourly demand plus fire flow conditions must be adhered to in
determining physical capacity. A water system's overall physical capacity must be determined in
ERUs from its most Jimiting design element. Bremerton's physical capacity is 56,711 ERUs
based on storage as identified in the calculations summarized in Table 8-3. The description of
the calculation of the physical capacity for each facility is described later in this section.

3. This value is the maximum number of ERUs that can be served by existing storage and was developed by changing
the MDD in the Max ERU column ofTables8-5, 8-11, and 8-12 until the Storage Surplus/(Deficiency) value equals
zero. The value for existing storage> 30 psi corresponds to the Equalizing Storage Capacity line and the value for
existing storage . .
>20 psi corresponds to the Total Storage Capacity line. The number of ERUs is calculated from the MDD based on
400 gpdfERU. There are two different values forthe number ofERUs for the existing storage >30 psi and >20 psi.
Note that in the tables one of the storage surplus/(Deficiency) values is zero and the other one is positive. When you
zero the other one, the one that is currently zero will become negative. The MDD total for both storage
surplus/(Deficiency) values was calculated and left in the one with a zero and a positive value in the final table.

The total number does not necessarily reflect the total volume in the pressure zone, but reflects the relative amount of
storage that is available above 30 or 20 psi and the required amount of storage. The number of ERUs that could be
served considering total storage capacity mayor may not be more than the total number that could be served
considering equalizing storage capacity.
The maximum number of ERUsthat could be served with the existing source, treatment, and
water rights is in excess of the existing number of customers projected for 2024( calculations
shown in Table 8-4). The total is limited by storage capacity.
Source capacity is calculated for both ADD and MDD conditions. The difference in source
amount for the two conditions is caused by differing assumptions for the surface source. For
ADD conditions, the capacity of the surface source is limited by the firm yield estimate of the
surface supply (5.6 mgd). For MDDconditions the surface source capacity is limited by the
treatment plant capacity (18.0 mgd). The calculation of source adequacy compares the available
source with the projected demand. The maximum number of ERUs that can be served is
determined when demand and source capacity are equal. The ultimate limiting factor is the lesser
of the totals for ADD and MDD conditions.

Apart from the system-wide storage inadequacy discussed above, specific pressure zones will be
deficient in storage prior to 2024. Detailed storage adequacy calculations are included in Section
8.4. Storage deficiencies are located in the western portion of the system. The CIP contains
items proposed to mitigate the deficiency and increase the system capacity to a level greater than
the proposed 2024 demands.

8.3 Fire Flow Analysis
One of the features of WaterCAD is the ability to run fire flow simulations at every node in the
system during a single modeling run. The model assigns a fire flow to each node individually,
and determines the available fire flow and residual pressure at that node, the minimum pressure
in that specific pressure zone, and the minimum pressure throughout the entire system.
Using the fire flow options in the model, each node in the Bremerton system was assigned a fire
flow of either 1,000 or 1,500 gpm, depending on whether the area was residential or commercial.
The simulation determined if the flow could be met while maintaining a minimum residual
pressure of 20 psi at all distribution nodes in the system during the 2004 MDD event with water
levels in the reservoirs set at the elevation where equalizing and fire flow storage are depleted.
After performing the fire flow simulation at every node in the system, the nodes that did not
satisfy the required fire flow while maintaining the minimum residual of 20 psi were singled out
for more detailed analysis. This analysis consisted of identifying specific pipe improvements
necessary to provide the required fire flow. The improvements were identified by assigning the
appropriate fire flow to a specific node and color-coding all the pipes according to head loss.
With the fire flow in place, the pipes with the highest head losses were upgraded until the fire
flow requirement was met. The fire flow was then moved to each different node on the
deficiency list, which potentially resulted in additional pipe upgrades to satisfy all fire flow
requirements. Some of the deficiencies were created not by a minimum pressure at the fire.flow
location, but by the minimum pressure being reached at a second node, typically located at a
higher elevation. In this case, the system capacity was increased to meet pressure requirements at
the controlling node.
Areas with a current fire flow deficiency are described below:
o The northern portion of the West 256 pressure zone. The central pipelines serving this area
have been identified for upgrading and are included in the Capital Improvement Plan (CIP)
under "Distribution Improvements."
. A portion of the East 490 pressure zone surrounding Reservoirs 12 and 13.
. A portion ofthe East 490 pressure zone surrounding Reservoirs 17 and 20.
. Southwest Bremerton near the airport in the West 517 pressure zone. The .transmission line
that serves the majority of the area will be increased as this area develops to allow for the
passage of water at fire flow rates. This line is effectively a dead-end line.
After the 2006 fife flow requirements were met by. implementing the pipe improvements, the
2024 MDD was applied to the model, and new fire flow simulations were run to see if any
additional upgrades were necessary. It was found that since the increase in demand from 2005 to
2024 is small compared to thel,OOOgpin fire flow demand, only a few additional upgrades were
necessary. All proposed improvements are included in the CIPunder "Distribution
Improvements. "
With the identified improvements in place, the fire flow simulations indicated a number of nodes
could not meet the minimum requirements. All of these nodes are located in the Boosted West
256 Zone (Lafayette Zone) served by Booster Station 3, which consists of one 300 gpm pump.
System Analysis
8-13
2005 City of Bremerton Water System Plan
A number of other nodes did not meet the minimum fire flow requirements for different reasons.
Six nodes spread throughout the system were unable to meet the 1,000 gpm demand, because
they were located on "dead end" pipes. This means that the pipe ended on the node and did not
loop back into the distribution system. The available fire flow at each of these nodes is close to
the required 1,000 gpm and could be considered adequate. The pipe improvements are included
in the CIP table for the sake of completeness. Each of these improvements should be evaluated
on a case-by-case basis.
8.4 Storage Analysis
DOH requires public water systems to provide sufficient storage to meet any seasonal or diurnal
variations in demand, fire flows, and emergency demands, such as during power outages and
equipment failures. These criteria are outlined in the Washington Water System Design Manual
(Design Manual), 1999. This plan utilizes these guidelines as criteria for determination of
reasonable treated water storage required in each pressure zone.
For a given reservoir design, each of the five storage components listed below must be
considered:
. Operational Storage
. Equalizing Storage
. Standby Emergency Storage
. Fire Suppression Storage
. Dead Storage, if any
Only effective storage may be used in determining actual available or design storage volume.
Effective volume is equal to the total volume minus the dead storage built into the reservoir (and
in Bremerton's case, any unusable storage in the top of Reservoir 6). Total storage volume
required has been interpreted as the sum of Equalizing Storage, Fire Storage, and Standby
(Emergency) Storage at an elevation sufficient to provide 20 psi (static) to the highest customer
in any pressure zone. In addition, equalizing storage is evaluated with respect to providing 30 psi
(static) to the highest customer in a pressure zone. Operational storage is any surplus storage that
is available after subtracting the other required storage components (Exhibit 8-1 in the Design
Manual). For this plan, storage requirements will be developed by pressure zone. The ability to
provide water from reservoirs to lower zones through PR V stations will be included in the
analysis.
While DOH will accept nesting of standby and fire flow storage, the Fire Districts served by the
Bremerton water system prefer the more conservative approach of including both portions of
overall storage separately.
8.4.1 Operational Storage
Operational storage is the volume of the reservoir devoted to supplying the water system
while, under normal operating conditions, the sources of supply are in "off' status.
Operational storage is additive to the other components of storage and provides an
System Analysis
8-14
2005 City of Bremerton Water System Plan
additional factor of safety. The volume of operational storage should be sufficient to
prevent excess pump cycling.
The amount of operational storage in each pressure zone is identified as the surplus
amount in each calculation.
8.4.2 Equalizing Storage
Equalizing storage capacity is utilized to meet the daily (diurnal) variations in demand.
Peak use periods typically occur during the morning and evening hours, especially during
the breakfast and dinner hours. Water is typically withdrawn from storage during these
peak demand periods and replenished during low demand periods in late evening and
early morning hours.
For systems like Bremerton that supply water to storage based upon the reservoir water
levels (on-calI-demand), DOH guidelines specify that the following equation be used to
estimate equalizing storage:
Equalizing Storage (gal) = (PHD ~ Qs) (150 minutes), where:
PHD Peak hourly Demand (gpm)
Qs Source production rate (gpm)
In most cases in Bremerton, Qs is greater than the PHD resulting in a negative value for
Equalizing Storage. In these cases, a value of 15 percent of the Maximum Day Demand
is used. At no time is equalizing storage calculated as less than 15 percent ofMDD.
8.4.3 Standby Emergency Storage
The purpose of standby storage is to provide a measure of reliability should sources fail
or when unusual conditions impose higher demands than anticipated. The volume of
emergency storage required is dependent upon the reliability of the source of supply and
the ability to provide an alternative supply. If the system or zone has multiple sources of
supply, placing the larger supply source out of service and calculating the volume of
water that could be provided by the remaining supply sources in gallons per connection
per day can reduce the standby storage requirement.
For this analysis, the largest source in any pressure zone is taken out of production before
the storage volume is calculated. Booster pump stations in a pressure zone are considered
a source in this analysis. For pump stations, the capacity of the largest single pump is
removed from the total source duringthis calCulation, not the full pump station capacity.
The recommended standby storage should not be less than 200 gallons per equivalent
residential units (ERU). For systems with multiple sources, the standby storage is based
on the following equation:
System Analysis
8-15
2005 City of Bremerton Water System Plan
Standby Storage (gal) = (2* ADD) (N) - tm (Qs- Qd, where:
ADD Average Day Demand/ERU (gpd/ERU)
N NumberofERUs
Qs Sum of all installed and available sources of supply in gpm
QL The largest capacity source available to the system in gpm
tm Time that remaining sources are pumped on the day the largest source is not
available in minutes (assumed as 24 hours)
The larger of the amount calculated in the equation above, or 200 gallons per ERU, is
used for Standby Emergency Storage in this analysis.
8.4.4 Fire Suppression Storage
Water systems are required to construct and maintain facilities capable of delivering fire
flows in accordance with the determination of the fire flow requirements made by the
local . fire protection authority while maintaining 20 psi pressure throughout the.
distribution system. Fireflow requirements are listed in Section 7.3 and range from 1,000
gpm for 2 hours (120,000 gallons) to 5,000 gpm for 4 hours (1,200,000 gallons),
depending on the pressure zone. The magnitude of the fire suppression storage is the
product of the maximum flow rate and duration established by the fire protection
authority having jurisdiction.
The minimum fire suppression storage for systems is the product of the required flow rate
multiplied by the flow duration and is based on the following equation:
Fire suppression storage (gal) = FF (tm), where:
FF = required fire flow rate
tm = Duration ofFF rate
8.4.5 Dead Storage
Dead storage is the volume of stored water not available to all customers at the minimum
design pressures and is excluded from the volumes provided to meet the effective storage.
Dead storage is assumed as that volume which is at an elevation lower than the elevation
necessary to provide 20 psi (static) atthe meter of the highest customer in any pressure
zone. Dead storage has been removed from the total available volume from each reservoir
in the tables that follow.

8.4.6 Bremerton System Evaluation
The eight previous tables were prepared to analyze the storage adequacy of the Bremerton
system.. The following pressure zones were evaluated as stand-alone features:
· Main System West Pressure Zones (West 256, West 440, and West 650) (Table 8-5)
· Main System West 440 Zone (Table 8-6)
· Main System West 256 and West 440 Zones (Table 8-7)
· Main System West 650 Zone (Table 8-8)
· Main System East 490 Zone (Table 8-9)
· Main System East 398 Zone (Table 8-10)
· Main System East Pressure Zones (East 240, East 398, and East 490) (Table 8-11)
. West 517 Zone (Table 8-12)
The individually listed pressure zones do not currently have the ability to receive water
from higher-pressure zones, so no storage located in higher pressure zones can be used in
their evaluation. The inclusion of an intertie between the West 650 Zone and the West
440 Zone is being considered.
The evaluation of the West 256 Zone includes the storage (and demand) for the West 440
Zone, since water can flow from West 440 into West 256 through a zone intertie (Table
8-7). No increase in storage is available in the upper zone when evaluating the lower
zone, even though the entire volume would be available at greater than 30 psi.
In a similar manner, the evaluation for the East 240 Zone (Table 8-11) includes the
storage and demands for the East 398 and East 490 Zones.
For the most part, the storage in Bremerton meets DOH requirements. Table 8-13
summarizes the results of the storage analysis. The combined western zones will be
deficient in equalizing and total storage by 2018. In the West 517 pressure zone, the
current required amount of equalizing and total storage is met by the existing reservoirs,
but the zone becomes deficient by 2007, assuming development takes place as projected.
If new development arrives in theW est 517 zone, new storage will be needed. The
combination of the West 256 and West 440 Zones will be deficit in total storage (greater
than 20 psi) by 2018, showing a deficit of approximately 2.4 MG by 2024.
All storage requirements (equalizing greater than 30 psi and equalizing plus fire flow and
standby greater than 20 psi) are currently adequate throughout the planning period in the
remaining pressure zones, including all the pressure zones in the eastern portion of
Bremerton.
Four small pressure zones have no storage and are served by booster pump stations. No
evaluation of these pressure zones was made.

8.4.7 Storage Recommendations
Based on the analysis above, new storage for the Bremerton system is needed to meet
long-term deficiencies. The sections below describe recommended improvements and
options to meet these storage requirements.
West 440 Zone
The West 440 by itself has adequate equalizing and total storage capacity through the 20-
year planning horizon.
West 256 Zone
The combined West 256 andW est 440 Zone analysis indicates that the two zones
currently have adequate storage with a total storage deficit of 2.37 MG by 2024.
Construction of a 2.5 MG reservoir will provide adequate storage for the full planning
period.
Additional storage must be constructed above elevation 241 to eliminate the deficit. This
new storage could be installed in either the West 440 or West 256 Zones to be available
to mitigate the deficiency. The Reservoir 5 site is a possible location for an additional
reservOIr.
A potential alternative to construction of new storage in the West 256 Zone is to reclaim
some of the dead storage in Reservoir 4 by converting the highest services in the pressure
zone to the West 440 Zone. This option will be evaluated by the City prior to pre-design
of any reservoir construction projects.
West 580 Zone
The West 580 Zone is currently under construction to be completed in late 2006. It will
be served by the new Pump Station 2a which will be operated from the level in the Port
orchard Fiegly Road reservoir. Storage needs will depend on the rate of residential
growth. Bremerton currently has plans to construct an additional 1 MG reservoir for this
zone in 2015.
Combined Western Zones
The combined western zones reflect the situation in the various individual zones. The
deficit of approximately 2.0 MG by 2024 can be solved by eliminating the storage
deficiency in the combined West256 and West 440 Zones.
East 240 Zone
This zone has no current or projected storage deficiencies.
System Analysis
8-36
2005 City of Bremerton Water System Plan
East 398 Zone
This zone has no current or projected storage deficiencies.
East 490 Zone
This zone has no current or projected storage deficiencies.
West 517 Zone
This zone has adequate equalizing and total storage for current conditions, and
experiences a deficit in equalizing storage by early 2007 and in total storage shortly
thereafter. Since this zone consists primarily of commercial and industrial development,
construction of new storage should be completed in stages as development occurs and
new storage is needed. Mitigation of the 6-year equalizing and total storage deficit
requires construction of a 1.0 MG reservoir with approximately 100,000 gallons above
elevation 486. Mitigation of the remaining projected deficit can be completed after 2011
or as development occurs.

Section 9
Capital Improvement Plan
9.1 The Capital Planning Process
A number of system improvements have been identified during the completion of this plan. The
development of the specific improvements has been described in the appropriate section. This
section combines the various improvements identified into a single listing which can be
prioritized and scheduled.
The City prepares a Capital Facility Plan (CFP) as required by the Washington State Growth
Management Act (GMA). This CFP is updated every two years and was last updated in 2004.
Kitsap County also prepares a CFP and it will be next updated in 2006. The Water Utility
updates its 20-year CIP every six years with the Water System Plan Update. The Utility updates
its six-year CIP annually at the beginning of the budget cycle in the second quarter of each year.
The GMA requires the improvements identified in the water system planning process be
consistent with GMA planning.
9.2 Identification of Recommended System Improvements
A listing of improvements to the Bremerton system has been created through the combination of
the following:
· Existing Bremerton Water Utility Capital Improvement Plan as approved by the City Council
for the years 2006 through 2011,
· Additional projects identified during the water hydraulic model analysis as performed as part
of this plan of Bremerton's source, storage, distribution, transmission, and water quality,
· Projects required to meet federal and state regulatory requirements, and
· Other projects identified by City personnel for the years beyond the approved CIP for the
years 2006 through 2011.
These projects have been combined into Table 9-1 showing project name, scheduled year of
activity, and estimated project cost. Cost for the pipe construction is based on $12.00 per inch
diameter per foot and include all project costs (construction, sales tax, engineering,
administration, etc.).
Each year, the Utility has allocated an annual amount for main replacement in the CIP which
funds both water main work as identified by the hydraulic analysis and substandard main
replacement. The list of anticipated distribution improvements is located in the appendices.
The Utility has outlined a plan to replace substandard mains, defined as generally being three
inches or less in diameter and need to be replaced for improved water service.
Additionally, the Utility allocates an annual amount for the following recurring capital
expenditures:
Capital Improvement Plan
9-1
2005 Bremerton Water System Plan
. Miscellaneous minor capital equipment and improvements for the Water Resources Division
. Miscellaneous minor capital equipment and improvements for the Utility Operations
Division
. Meter replacement
. New taps and meter installation
. Fire hydrant installation
There are several major projects projected for the Utility that are not part of the CIP but are
funded through operations and maintenance expense such as the water system plans required
every six years, other water planning and reports, and reservoir coatings.
CIP projects are categorized according to the reason required:
. Maintenance
. Replacement or upgrade (not growth-related)
. Required to meet state and federal regulations
. Growth-related upgrade
9.3 CIP Schedule
The City has already approved the existing CIP schedule for projects scheduled from 2006
through 2011. Water projects scheduled from 2012 through 2025 have been identified by City
personnel, were developed during hydraulic modeling, will be required by regulations, were
recommended by studies, or are required to serve growth. The schedule is based on their relative
priorities. Those with high priorities are scheduled to be built between 2006 and 2011. Those
with lower priorities are scheduled for later years.
Funding for the CIP program comes from rates, grants and loans, and revenue from timber
harvest on Utility-owned land.
On a regular basis the Water Utility conducts a Cost of Service study to determine the revenue
needs. An annual amount is allocated for CIP projects. Financial planning is more fully
discussed in Section 10.

2005 City of Bremerton Water System Plan
Section 10
Financial Plan
10.1 Introduction
The effective implementation of a Water System Plan (WSP) is dependent on accurately
developing a plan that can be financially supported by the utility, will meet State and local
regulatory requirements, and provides the flexibility to deal with unforeseen changes.
This chapter presents a financial plan that reviews the revenues and expenses for the City of
Bremerton's (City) water system. The financial plan includes projected operating and capital
costs of the system for the six-year time horizon of 2006 to 2011. The revenues and expenses
used in the financial plan were obtained from the City's 2005 budget in conjunction with
historical consumption information. The capital costs contained within the financial plan utilize
the Capital Improvement Plan (Crp), which was developed for the City's water utility rate study,
recently updated in 2005. The results of the financial plan outline the annual operating and
capital needs of the water system and determine if current water revenues are sufficient to cover
costs. This analysis is not intended to be sufficient to provide a detailed review of cost of service
or various alternative rate designs; however, the City recently completed a rate study in 2005
independent of this planning document to address those issues. In addition, Bremerton's
conservation-oriented rates are being reviewed as part of this project.
10.1.1 Past Financial History
The past six years of financial information for the water utility were evaluated to gain an
understanding of the past performance of the utility, and at the same time, gain
perspective on the current financial status of the water utility. Table 10-1 is a summary of
a six-year financial history (2000 to 2005) for the City's water utility.
The utility has an adequate financial position. As Table 10-1 illustrates, the utility is
showing a positive cash flow for the historical test period. The balances are used for
capital improvements and reserved for future capital needs.
While some capital improvements are funded through low-interest loans and revenue
bonds, resulting in debt service payments, historically the utility has also funded a
substantial portion of its capital improvements through rates. Target levels for funding
capital improvements for future years are discussed later in this section.

10.1.2 Development of the Financial Plan
A six-year financial plan was developed to determine the City's ability to meet its capital
improvement and operating needs over the six-year review period. In developing the
financial plan, fund balance and reserve levels were also analyzed. The financial plan was
developed to review the projected revenues and expenses of the water system between
2006 and 2011. The City's 2005 budget was used as a base. Future years were escalated
by applying factors for inflation and growth, as described below.
10.1.3 Revenue
The first component of the financial plan is a review of the sources of revenue of the
water system. The different revenues received from operations are:
. Revenues from services - rates, connection fees, timber sales, service repairs, fines
and penalties, ancillary fees;
. Miscellaneous revenue - interest earnings on fund balance, lease payments;
. Other income - General Facility Charges, grants;
Financial Plan
10-2
2005 City of Bremerton Water System Plan
. Non-revenue receipts -loan proceeds; and
. Other financing sources - sale of assets.
Projections for future year rate revenues were developed by applying a projected growth
rate of one percent to the 2005 budgeted rate revenue. Other miscellaneous revenues,
including investment interest, penalties and other revenue, are projected to increase
approximately one percent per year through 2011,.
Rate revenues are projected to be $7.3 million in 2006. The rate revenues of the City
come from retail sales to the residential and commercial customers and Puget Sound
Naval Shipyard (PSNS) sales. With growth applied at one percent per year, the rate
revenue is estimated to increase to $7.7 million by 2011.
Other revenues for 2006 total approximately $460,000, with a majority of the revenue
stemming from long-term facilities leases (such as cell towers) and water connection
charges. The total amount of other revenue increases over the six years, reaching
approximately $485,000 by 2011. The total revenue available to offset the operating and
capital requirements of the water system totals $7.8 million in 2006, and is projected to
increase to $8.2 million by 2011.
10.1.4 Expenses
The projection of future operating expenses, or the application of funds, is based on the
2005 budget. These expenses are projected for future years by applying the escalation
factors pertinent to the type of expense being reviewed. The second part of the financial
plan is a review of the applications of funds. In developing the financial forecast, four
main cost components were reviewed:
. Operations and Maintenance (O&M) Expenses
. Taxes and Transfer Payments
. Debt Service
. Capital Improvements Funded from Rates
Operation and Maintenance Expenses
Using the 2005 budget as a starting point, expenses were escalated by factors representing
assumed inflationary rates to obtain projected costs. Escalation factors range from
employee benefits (combined with other increasing labor costs) at an estimated annual
increase of7.6 percenUo miscellaneous equipment, materials, and supplies at one percent
each. Purchased power was calculated at anescalation of three percent per year. Detailed
escalation factors are provided at the end of this section.
While operating costs increase in some areas for regulatory compliance with IDSE and
other monitoring requirements (including approximately $5,000 per year for
cryptosporidium in 2007 and 2008) in future years, as noted in Section 4, the Water
Resources' professional services budget remains at average annual expenditure levels of
Financial Plan
10-3
2005 City of Bremerton Water System Plan
$100,000 per year (reducing the 2006 budget level by $165,000). The inflationary
escalation factors still show an overall increase in the operation and maintenance budget
for future years. IDSE future compliance costs are shown in 2011 at $8,000 per year.
Additional operation and maintenance costs for the ultraviolet (UV) water treatment plant
were identified in a treatment option evaluation and are projected to begin in 2011,
adding $63,000 to operations and maintenance expenses.
No other program cost increases above budget year 2006 figures were assumed as part of
the projected costs. Operation and maintenance expenses ranged from $6.85 million in
2006 to a projected $8.37 million in 2011.
Taxes and Transfer Payments
The water system currently has tax obligations to the State in the form of excise taxes.
The state public utility tax is calculated as 5.029 percent of the water utility rate revenues.
For 2006 these taxes/transfer payments total approximately $1 million through 2011.
Projected taxes for the period assume constant tax rates over time.
Debt Service
According to City financial records, two Public Works Trust Fund (PWTF) and nine
Drinking Water State Revolving Fund (DWSRF) loans relate to the water utility. An
annual payment of approximately $180,000 for a 1998 PWTF loan for the 36" water main
is completed in 2019. The annual payment of approximately $12,000 per year for the
1999 PWTF loan to the Tracyton Water District is estimated for the planning period.
The City's nine DWSRF loans are for various projects. The larger loan amounts are for
the following projects: East-West Flow Improvements, the Casad Dam Seismic Retrofit,
Casad Dam HB Valve, Pump Station 4 Upgrade, and the Tracyton Water District
Upgrade. Additional, smaller seismic and retrofit type projects also exist. The DWSRF
loans total about $510,000 per year in debt service payments. The final amount is an
annual Utility Local Improvement District (UUD) payment of $61,500 per year. This
amount is offset by a similar funding revenue level (UUD revenues).
The combined debt service on the existing debt averages approximately $770,000
between 2006 and 2011. The model used to develop the financial plan indicates that the
City plans to apply for additional loans through 2011 to meet the capital needs identified
within this plan. These projected loans add an additional $540,000 of debt payments by
2011, for a total projected debt service of $1.3 million by 2011.
Meeting debt service coverage (DSC)requirements is an important financial indicator for
well-managed utilities. Debt service coverage is a financial measurement of an entity's
ability to repay debt. A DSC ratio is a comparison of net income before debt service
payments to the total debt service on revenue bonds or of all outstanding debt service. A
DSC ratio of 1.25 or 1.30 is generally considered the legally acceptable minimum for
revenue bonds. However, the City has established written financial policies that target a
debt service coverage ratio of 1.50 or above. The City meets this requirement every year
Financial Plan
10-4
2005 City of Bremerton Water System Plan
except in 2011, when additional operating costs for UV treatment are scheduled to begin.
The City will need to be watchful of this planning requirement during its financial
evaluations.
While no revenue bonds require the 1.5 DSC ratio test at the current time, it is an
important financial indicator to rating agencies if the City decides to pursue revenue bond
funding any time in the future. The City does have outstanding revenue bonds for its
wastewater utility for which the DSC coverage ratio is calculated and met on a combined
utility basis.
Capital Improvement Projects from Rates
Capital improvement projects (CIP) are related to the infrastructure of a utility. CIPs are
generally divided into two categories: capital improvements related to renewal and
replacements of the existing plant (depreciated facilities), and growth-related projects,
including system expansion and upgrades to accommodate new customers.
The City capitalizes some staff time and benefits for those staff working on capital
projects. In addition, planning and construction projects are included within the capital
component of the financial plan. The financial analysis conducted for this plan has
incorporated the capital projects outlined in the 2005 rate study and modified by Section
9 of this plan. These projects have been allocated by year in order to quantify the annual
capital requirements for the planning period. Identified CIP totals range from
approximately $1.9 to $4.6 million per year from 2006 to 2011.
It is not anticipated that the City will use a large amount of reserve funding to cover its
capital improvements. Reserve funds are discussed later in this section.
As prudent practice, a utility should fund a portion of its capital improvements from rates
on an on-going basis. The City is not expected to have any remaining capital fund
balance in 2006; however, an increase in rate-funded capital (from approximately
$300,000 in 2006 to $765,000 in 2011) and continued steady timber sales funding
(averaging around $1.1 million a year) should not only cover capital improvements, but
build a positive balance in the ending capital reserves, reaching $720,000 in 2011.
The capital analysis assumes that any additional funding beyond what is necessary to
meet the annual capital requirements will be placed into the working capital reserve for
future capital needs.
10.1.5 External Sources of Funds for Capital Projects
The City has the ability to apply for grant arid loan funds available to public entities for
water system projects and has been successful at obtaining a number of low-interest
loans, as described earlier under the debt service section. Table 10-2 provides a summary
of information for various funding agencies. These sources rarely provide full funding of
a construction project. The City needs to supplement any of these funds with matching
Financial Plan

funds to meet eligibility criteria and to ensure implementation of the recommended
capital improvement projects can occur.

A brief description of these funding sources is provided below.
DeparlmentofEcorogy
The Centennial Clean Water Fund (CCWF) is available to local governments and tribes
for measures to prevent and control water pollution. Both grants and loans are available
on a yearly funding cycle.
CCWF is the largest State grant program for water projects. It provides funding for
planning, design, and construction of facilities and other activities related to water
quality. The primary focus of the program is pollution prevention and funding projects
with a quantifiable water quality benefit. Funds are available to protect a source of water
supply, and implement wellhead protection, water conservation, and water reuse projects
if they can be shown to be the cost-effective alternative to solving a water quality
problem. Funding from this program is not available to provide excess capacity or a
source of supply, but must be used to meet existing customer needs.
Interest rates are 0.5 percent for loans up to five years, while loans over five years but less
than 20 years have a 1.5 percent rate. Grant funding of 50 to 75 percent ofa project can
be available, depending on the type of project.
Another source of Washington Department of Ecology (Ecology) grant funding provided
by the Remedial Action Grant Program is normally used only to mitigate contamination
events.
Financial Plan
10-6
2005 City of Bremerton Water System Plan
Washington Department of Health
The SDW A appropriates funding for states to develop their DWSRF loan programs.
Each state receives annual allocations in the form of a capitalization grant. In Washington
State, the DWSRF is jointly managed by DOH Division of Drinking Water and the Public
Works Trust Fund Board (Board), along with its partner, the Department of Community,
Trade and Economic Development.
DWSRF loans are available to all community public water systems and non-profit, non-
community public water systems, except federally-owned and State-owned systems. The
loans may be used to address SDW A health standard violations, replace infrastructure for
SDW A compliance, or consolidate supplies and acquire property if needed for SDW A
compliance.
The interest rates on DWSRF loans are 1.5 percent for the basic rate or one percent for an
"economically distressed county," as determined by the DWSRF guidelines. They apply
a one percent loan fee on all loans. The interest rate can be dependent on the overall
economic situation of the area. If 51 percent of the area's households are below 80
percent oftheniedian income for the county, the interest rate drops to 0.5 percent, ahd if
the 51 percent are at or below 50 percent of the county median income, the loan has a
zero percent interest rate. In this case the loan has a 30-year (or life of the project) period,
while all others have a 20-year (or life of the project) period.
Public Works Trust Fund
The PWTF loan program is set up by the Washington State Legislature to assist cities,
towns, counties, or special districts with funding for different types of public works
projects. The projects can include streets, roads, drainage systems, water systems, and
sanitary sewer systems. The emphasis of allocating funds is for replacement and repair of
existing systems. Funds are not allocated to install new water systems but are granted to
rehabilitate or replace existing systems serving an existing population.
The loans are issued atup totwo percent interest rate for a maximum term of 20 years or
the life of the project for applications requesting 95 percent project funding. The interest
rate decreases to 0.5 percent when applicants provide at least 15 percent of the project
funding. Debt service coverage is not imposed on the PWTF loan.
Infrastructure Assistance Coordinating Council
Numerous other programs with funding are available for various other aspects of water
utility capital projects. The Infrastructure Assistance Coordinating Council (Council)
provides resources and conferences on the available funding sources. The Council is
comprised of State and local organizations whose function is to provide funding for
infrastructure repair and development. The purpose of the Council is to assist local
governments in coordinating funding efforts for infrastructure improvements. This is an
important resource, as the Council will be aware of any new funding opportunities that
may anse.
Financial Plan

2005 City of Bremerton Water System Plan
While the above list of possible grant and loan opportumtIes for the City is not
exhaustive, it does highlight the most probable outside funding sources, excluding
revenue bonds and other external sources of funds, available to the City for its water
capital improvement needs. These other external sources of funds are described below.
Revenue Bonds
Revenue bonds are supported by the income generated from monthly utility charges. The
City Council can issue revenue bonds at its discretion. Water rates must be high enough
to pay system operation and maintenance costs plus the annual principal and interest cost
(debt service) of the bond issue.
F or investors to buy revenue bonds, rates must include adequate revenue to provide for
"coverage." The normal coverage is 20 to 30 percent of the debt service, depending on
the financial strength of the City.
Utility Local Improvement Districts
Projects benefiting a specific area of adjacent properties can be funded through utility
local improvement districts (UUD). After a UUD is formed, the cost of the project can
be assessed against the benefited properties in proportion to its share of the total benefits.
The amount of the assessment cannot exceed the increase in the value of the property
resulting from the project.
A UUD combines property assessments and revenue funding from water rates. The
additional security of the bonds tends to bring lower interest rates. Flexibility and equity
are also gained, as the City can accommodate the cost of special construction problems or
upsizing the distribution system.
Developer Extensions
Under a developer water main extension, the owner of a development requests water
service. Filing fees usually cover administration costs only. The developer pays all costs
of the extension and turns the facilities over to the City for operation and maintenance.
10.1.6 Internal Sources of Funding for Capital Projects
Internal funding sources available to offset capital costs include contributions received
from new water customers for their capacity impact on the system. The City updated its
water general facility charges (system development charges) in 2004. The 2006 charge
for a 5/8" x 3/4" meter connection is $2,369. . The charges increase by meter size, as the
capacity of the meter increases. These charges are adjusted annually to keep up with the
Construction Cost Index. The City should also conduct a comprehensive update of these
fees every 3 to 5 years, or as new major capacity-related projects are undertaken.
As noted earlier, the City also uses available reserves for capital projects, as available.

When interpreting the results of Table 10-3, it is important to understand that the "Rate
Adjustment Required" is cumulative. That is, any rate adjustments made in previous
years would reduce what is required in the following years. If no adjustments were made
prior to 2008, a 13.8 percent adjustment would be required. The model assumes expenses
are completely expended within each year. Typically, utilities receive additional revenue,
and actual expenditures do not always total 100 percent of budget appropriations.
Therefore, the City has a number of options for deferring rate adjustments until the latter
part of the planning period. Those options would include adjusting capital improvement
timing, using more reserves for capital improvements, reducing some other operating
expenses, and closely monitoring additional revenue or increased growth beyond the one
percent assumed.
The results of Table 10-3 show that existing rates are insufficient throughout the planning
period under review. A "proposed" level of adjustment needed to transition the rates
over time is provided in Section 10.1.10.
Financial Plan
10-9
2005 City of Bremerton Water System Plan
The financial plan presented in this section is predicated upon an assumed level of growth
on the system (1.0 percent per year) and assumptions related to inflation. Should this
growth increase, slow down, or not occur, the level of rate adjustment required will be
affected. If costs escalate faster or slower than indicated in this plan, the projected rate
adjustments shown in Table 10-3 would also be affected.
10.1.8 Reserve levels
A key indicator of a utility's financial health and viability is its reserve levels. Because a
majority of the utility's revenue is consumption-based, and therefore dependent upon
weather conditions and usage patterns, maintaining adequate reserve levels is important
for stable fiscal management. A discussion of the utility's reserves is provided below.
Industry standards (American Water Works Association - AWWA) recommend that
utilities maintain working capital reserves at a level adequate to handle unexpected
occurrences, including unexpected cash flow fluctuations. A balance for an operations
and maintenance reserve, or operating reserve, is recommended to be a minimum of 45
days (12%) of operations and tax expense. For the City, that minimum balance would
equate to approximately $1 million inthe first half of the planning period, increasing to
$1.2 million by 2011. The Cityhegins theplanningperiod in 2005 with a balanceof$2.l
million in working capital. The balance increases throughout the time period due to
capital needs being lower than available funding. The 2011 ending balance is
approximately $3.4 million. Maintaining this balance will provide the city with
flexibility in meeting future capital requirements.
The City currently has a balance in the capital reserve fund. In 2005, this reserve is
unfunded, but grows over the review period to $720,000 by 2011. Sound financial
policies indicate that a capital. fund balance equal to an average year's worth of capital
projects is a prudent reserve amount. For the City, this minimum capital fund target
would be $3.4 million. Within the City's policies established in the 2004 rate study, a
minimum target of six months of construction expenditures is to be in reserve. That
would be approximately $1.7 million. Another measure used for a minimum target
balance of capital reserve can be 1.5 percent of original plant value. For the water utility,
that value is $1.4 million. The City will continue to watch this reserve level in future
years and build to the minimum target level whenever. revenue exceeds the capital
expenditures of a given year. Between the capital fund balance and the working capital
reserve, the City's reserve levels are more than adequate to meet this target.
The reserve review indicated that the City has adequate reserve funding to meet
unanticipated obligations and genetaloperating fluctuations. The City has improved the
financial stability of the Utility by clarifying financial planning goals and policies that
define the appropriate reserves and other financial guidelines as part of the 2004 rate
study.

10.1.9 Review of the Existing Water Rates
Various "generally accepted" water rate structures can be used to establish or develop
rates. The initial starting point in considering a rate structure is the relationship between
fixed costs and variable costs. Fixed costs are generally collected as a fixed charge on a
monthly basis (e.g., $5.00 per month/meter). This charge may be called by various names
(e.g., customer charge, meter charge, base charge, etc.) but in all cases, it is intended to
collect those fixed costs the utility incurs.
Currently, the City has both a meter charge for service and a commodity charge based on
usage. For a residential customer, the meter charge is a minimum charge. Different rate
schedules apply to customers in different parts of the service area - inside the City, the
County (including the Port of Bremerton and Rocky Point), Tracyton, and Jackson
ParklPSNS. For purposes of this overview, the rates in effect as of January 2006 are
presented in Table lO-4.

wholesale and fire-lines. The monthly bill for a City retail customer using 1,000 cubic
feet of water (10 CCF) would be $19.22. A monthly bill for an average County customer
using the same amount would be $28.83.
The City's meter charge is based on the size of the customer's meter. This approach is
used often to recognize that different meter sizes place different demands and capacity
requirements on the system. It is common to base the meter charge rate differential on
the A WW A safe operating capacity of the meter. The meter capacity approach is
summarized in Table 10-5.

Table 1 0-5 shows the fixed meter, or base charge, increases in relationship to the A WW A
safe operating capacity of the various meter sizes. Meter capacity is an important concept
in that a customer that has a 2" meter is regarded, from a capacity perspective, as the
equivalent of eight 5/8 x 3/4" customers. For instance, the customer with a 2" meter is,
from a capacity perspective, the equivalent of eight (8) single-family homes with 5/8 x
3/4" meters. Since a large portion of costs is generally related to meeting capacity
requirements, it is important to take capacity into account when establishing rates for
customers. The City's current meter charges do not follow these capacity ratings exactly
and reflect local and unique circumstances related to its larger metered customers.
The conceptual rate review undertaken indicates that the City's water rates are
contemporary and attempt to capture the cost differential to serve customers with varying
facility requirements based on their location.
10.1.1 o Overview of FutureWaterRates
Based upon the results of the financial analysis, the City will require adjustments in rates
in future years to meet the on-going operational and capital needs of the Water Utility.
Table 10-6 shows the level of rate adjustment needed in future years for the 5-year
projected period to meet operating and capital costs as identified within this plan.

Adjustment
From the City's 2004 rate study and the updated revenue requirements in 2005, the City
has shown its commitment to implementing the necessary rate adjustments in order to
meet operating and capital costs and to meet debt service obligations. The adjustments
shown above will need to be applied to all portions of the rate design, or specific rate
design adjustments will need to be developed in order to ensure proper levels of revenue
are achieved to meet the overall revenue requirement of each year.
The City has expressed an interest in reviewing its' two'-tier conservation-based rates.
Some alternative rate structure options for the Cityto consider are described below.
10.1.11 Conservation-Based Rate Design Options
The City has implemented a number of conservation programs over the past several years.
In addition to these programs, water rates can be an effective tool in improving efficient
use of the water resource. A number of water rate structures can encourage efficient use
of the City's drinking water resources. These include inverted-block rates, seasonal rates,
and tailored rates. These rate designs require varying degrees of data and management
for implementation.
When considering conservation-based rate structures, certain rate structures are more
applicable for certain customer classes of service. This is because one of the approaches
in establishing conservation-based rates is to target the discretionary usage of the
customer.' Outdoor watering is considered a more discretionary use than indoor use.
Studies have consistently shown that the elasticity associated with outdoor use is more
sensitive to changes in price than indoor use. At the same time, an inverted-:block rate
structure for commercial customers may not be appropriate or difficult to establish given
the varying consumption patterns of these customers.
A first step towards implementation can be inverted-block rates, especially for residential
customers. Fora residential rate structure, the block sizes or tiers are generally sized
around average indoor use, average outdoor use, and inefficient or wasteful use. The
number of blocks or tiers may Vary, but generally some rationale exists for establishing
the various block sizes and targeted consumption (discretionary vs. non-discretionary).
The pricing of each block increases - use more, pay more. As a point of reference, the
City implemented a first step in an inverted'-block, or tiered rates, in 2005. The City may
further refine these rates and is evaluating the potential of other measures to encourage
Financial Plan
10-13
2005 City of Bremerton Water System Plan
water resource conservation. These rate refinements will be reviewed later in 2006 along
with other conservation measures.
Seasonal rates are another alternative for consideration. In some cases, inverted block
rates may not be appropriate for certain types of customers, but seasonal pricing may be.
The intent of seasonal pricing is to provide a price signal to the customer of the higher
costs associated with summer peak use. Seasonal rates can also be combined with
inverted block or tiered rates.
A relatively new conservation-based rate structure is a water budget or tailored rates. In
simplistic terms, these are a variation of an inverted block rate, but the size of each block
is individually determined for each customer based upon the number of inhabitants in the
home, lot size, irrigation requirements, etc. These rate forms have had very limited
introduction into the water utility industry due to a number of factors. Among these are
the very high administrative costs associated with implementing these rates and
determining individual customer block sizes. At the same time, most, if not all, utility
billing programs are unable to handle thisparticular rate structure without some custom
programming. Where water budget rate structures do seem to have an excellent
application is for irrigation customers. The block sizes for the irrigation customer are
tailored for the specific property being irrigated.
10.1.12 Summary
The financial plan results presented in this section indicate water rates for the six-year
projected time horizon of 2006 to 2011 will require adjustments to fund the projected
operations and maintenance, capital, and debt service requirements. The City has an
interest in enhancing the conservation message within the existing rate structure some
time in the near future. The City is committed to the responsible management of the
Water Utility by past rate adjustments and by funding adequate levels of operations,
capital, and reserves. Continued fiscal management will enable the Utility to continue to
operate on a financially sound basis.

lter Reclamation Checklist for Systems with 1,000 or more Connections
,
The Municipal Water Supply - Efficiency Requirements Act, Chapter 5, Laws of2003 (Municipal Water
Law), amended Chapter 90.46 of the Revised Code of Washington (RCW) to require public water systems
serving 1000 or more connections to evaluate opportunities for reclaimed water when completing their
water system plans (WSP). This checklist may be used to ensure that your WSP includes sufficient
information about opportunities for reclaimed water and your system's efforts to develop those
opportunities.
Water System Name: City of Bremerton Main System and West 517 Pressure Zone
Date: July 2006
PWS ID: 08200R and 082734
1. An evaluation of water reclamation opportunities is found in the WSP on pages: 3-24
At a minimum, include the following in your evaluation of reclamation opportunities:
. An inventory of large water users.
. Identification of potential reclaimed water users.
. Estimates of how much water could be saved by development of reclaimed water projects
. Identification of opportunities that your system intends to pursue within the next six years
. A brief analysis ofthe financial and operation feasibility of identified opportunities
The form on the opposite side of this page is provided to assist you in conducting an inventory of
potential users and estimate savings. Use of this form is optional.
The City of Bremerton completed a "Water Reuse Feasibility Study" in 1998. A
copy of this document is enclosed. The City of Bremerton was involved in the
WRIA 15 watershed planning process which also evaluated reuse opportunities.
As an extension of the WRIA process, Bremerton was also involved in the "WISER
Water" (Wetland, Irrigation, Stream Enhancement, Recharge--water recycling)
project. A thorough evaluation of reuse opportunities at Kitsap County wastewater
treatment plants was conducted; however, Bremerton was not one of the top
candidates selected for further funding. A copy of the final documentation has
been requested and will be forwarded as soon as it is received.
Form From DOH March 2004 Revision
2. Provide the results of that evaluation.
Ifnew or additional reclaimed water opportunities are available, include a brief description
of activities you are considering undertaking or those activities you will undertake to pursue
development of those opportunities.
If reclaimed water opportunities are not available, include a brief description of the
interaction with the local wastewater facility (or other entity within the area you serve that
may be a generator of reclaimed water) to evaluate opportunities to develop reclaimed
water.
Please see enclosed reuse feasibility study. The reuse section of the City of
Bremerton Water System Plan states:
The City owns and operates a secondary wastewater treatment plant (WWTP) with an
average flow of about 6.2 MGD which could potentially be reclaimed after further
filtration. Water reuse is the beneficial use of reclaimed wastewater treatment plant
effluent in compliance with Washington Departments of Ecology and Health
regulations.
Bremerton's WWTP currently uses reclaimed secondary wastewater effluent for
process control, odor control, and to irrigate inside the WWTP grounds and at a
neighboring business. Approximately 150 gpm is used for in-plant uses and an
additional 120 gpm are used in the summer months for an annual total of 88 MG/year.
A "Water Reuse Feasibility Study" completed in 1998 identified the potential demands
for and costs to provide additional reclaimed water to potential users in the Bremerton
area. Bremerton's wastewater has higher than average saltwater from collection
system infiltration and Puget Sound Naval Shipyard inflow making reuse possibilities
challenging.
A 2005 County-wide reuse study indicated that Bremerton had the least potential for
large-scale reuse and recommended grant funding be focused at other locations with
more feasible reuse opportunities. The City is currently evaluating the next step to
take in reuse.
3. If evaluation of water reclamation is not included because such an evaluation has been
completed by the wastewater facility, or other entity, please include a copy of that
evaluation.

4. If water reclamation is mandated for this water system through local government agreement,
contract, local regulations, ordinances, or other mechanism, please provide a copy of the
governing mechanism.

Drinking Water
Quality Report
2005
Celebrate National Drinking Water Week
May 1 - 7,2005
Call 473-5920 for more information.
Bremerton Drinking Water Quality is Excellent
The City of Bremerton Water Utility is pleased to provide you with its annual water quality report and
proud that your water continues to be of the highest quality. The City is committed to safeguarding its
surface and groundwater sources. This brochure summarizes the test results for water provided to
over 50,000 customers last year and is a record reflecting the commitment of Water Utility employees
to deliver you excellent quality water. Included are details about:
. where your water comes from,
. what it contains, and
. how it compares to standards set by regulatory agencies.
Safe drinking water is essential for our citizens who need to be well-informed to wisely utilize and conserve water
resources and to support the improvements necessary to maintain the highest quality drinking water possible.
Protecting Our Water Supplies
Surface water from the Union River All.
Reservoir and groundwater from . I .
production wells located in the Bremerton N
area provide the supply for Bremerton's
water. All sources are managed in
accordance with Washington State Department of
Health and Federal Environmental Protection Agency (EPA)
regulations and best management practices for water supply
systems. Bremerton owns and protects the 3,000 acre
watershed surrounding the Union River supply. Access
to the watershed is secured, patrolled, and limited to
water supply and forestry management activities.
Each year the Washington State Department of
Health inspects the surface supply. Groundwater
wells are also safeguarded through efforts to
protect critical areas around the wellheads. All
waterfacilities are monitored and patrolled.

Bremerton Water Needs Minimal Treatment
Bremerton's water system is operated and maintained by experienced personnel and certified by the
State. The Washington State Department of Health determined Bremerton's Union River water source to
be of such good quality that the City is not required to install a filtration facility as long as all water quality,
operational, and watershed protection requirements are met. Bremerton consistently meets these quality stan-
dards. Treatment of Bremerton's water currently consists of chlorine to control microbes that might be present in the water
and sodium hydroxide for corrosion control. Corrosion treatment is required to prevent Bremerton's water from
leaching lead from customer's household plumbing. Sampling results confirm this treatment is successful in achieving
corrosion control.
The City of Bremerton performs systematic flushing of the water distribution system. Customers are notified about fluship'"
through newspaper ads and neighborhood signs. Flushing is a process of sending a rapid flow of water through the mail
"-.
to clean them. This helps to maintain water quality by removing sediment. Flushing may cause a temporary discoloration
to your water. While this discoloration is unpleasant, it is not harmful. If this happens, wait thirty to sixty minutes. Then turn
on your cold water and let it run for one to two minutes. If your water does not clear up after this process, please call the
Customer Response Line at 473-5920.
Information From EPA
Sources of drinking water (both tap and bottled water) include rivers,
reservoirs, springs, and wells. As water travels over the surface of the land
or through the ground, it dissolves naturally-occurring minerals and, in some
cases, radioactive materials and can pick up substances resulting from the
presence of animal or human activity. Contaminants that may be present in
source water are microbes, pesticides, herbicides, organic and inorganic chemicals, and
radioactive materials. To ensure tap water is safe to drink, the Environmental Protection
Agency (EPA) prescribes regulations limiting the amount of certain contaminants in water
provided by public water systems.
Drinking water, including bottled water, may reasOnably be expected to cOntain at least small amounts
of some contaminants. The presence of contaminants does not necessarily indicate that water poses a
health risk. More information about contaminants and potential health effects can be obtained by calling the
EPA's Safe Drinking Water Hotline at 1-800-426-4791.
Some people may be more vulnerable to contaminants in drinking water than the general population.
Immuno-compromised persons, such as those undergoing chemotherapy, persons who have undergone
organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants, can
be particularly at risk from infections. These people should seek advice about drinking water from their health
care providers. EPA guidelines on appropriate means to lessen risk of infection by Cryptosporidium and other
microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791. Please note that
Bremerton has tested for Cryptosporidium since 1994 and has never detected this organism in the water source.

Bremerton Water is a Great Value
Your water rates pay for delivering high-quality water to your tap and keeping the water system in top con-

D. SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS
(do not use this sheet for project actions)
Because these questions are very general, it may be helpful to read them in conjunction with the list
of the elements of the environment.
When answering these questions, be aware of the extent the proposal, or the types of activities
likely to result from the proposal, would affect the item at a greater intensity or at a faster rate than
if the proposal were not implemented. Respond briefly and in general terms.
1. How would the proposal be likely to increase discharge to water; emissions to air; production,
storage, or release of toxic or hazardous substances; or production of noise?
If population increases as forecasted in the Water System Plan there will be an
increase in water use and in discharge of wastewater and septic systems. None of
the other items listed will be affected.
Proposed measures to avoid or reduce such increases are:
Included in the Water System Plan is a comprehensive water conservation program
to encourage per capita reduction in water use.
2. How would the proposal be likely to affect plants, animals, fish, or marine life?
There should be no impact from projects proposed in the Water System Plan.
Measures for protection or conservation will be considered during design and
specific impacts will be evaluated at the project level.
Proposed measures to protect or conserve plants, animals, fish, or marine life are:
This plan is compatible with existing and proposed shoreline use plans.
3. How would the proposal be likely to deplete energy or natural resources?
As water demands increase, more energy will be needed to pump water from wells
and to higher pressure zones.
Proposed measures to protect or conserve energy and natural resources are:
Included in the Water System Plan is a comprehensive water conservation program
to encourage per capita reductioninWater use.
Page 14 of 15

4. How would the proposal be likely to use or affect environmentally sensitive areas or areas
designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild
and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands,
floodplains, or prime farmlands?
Impacts to sensitive areas or other designated critical areas will be evaluated
during the design and environmental review of specific projects in this plan.
Proposed measures to protect such resources or to avoid or reduce impacts are:
None needed at this time.
5. How would the proposal be likely to affect land and shoreline use, including whether it would
allow or encourage land or shoreline uses incompatible with existing plans?
This plan is compatible with existing and proposed shoreline use plans.
Proposed measures to avoid or reduce shoreline and land use impacts are:
6. How would the proposal be likely to increase demands on transportation or public services and
utilities?
Plan propos'es to respond to projected increase in needs for water service resulting
from projected population growth in the service area. Increase in demands on
public services and utilities resulting from growth will be determined by zoning,
land use, and the demand for public services.
Proposed measures to reduce or respond to such demand(s) are:
None needed.
7. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or
requirements for the protection of the environment.

Bremerton water officials
are thinking ahead to make
sure the city can supply wa-

New water supplies, con-
servation efforts and possibly
reuse of sewage effluent are
part of a plan to stretch water

"Water in general is some-
thing that most people don't
think about untH it is not
there," said Cahall.
State Jaw requires water
systems to update their pians
regularly, and a new law calls
for a separate plan dealing

month are expected to re-
quire all water systems to in-
stall water meters for their
customers within 10 years.
That's the best way to ensure
that the water is going where
it is supposed to go and re-
duce waste, said Leslie Gates
of the state's Office of Drink-
ing Water.
Bremerton customers use
an average of 186 gallons of .
water per day. compared to
a Western Washingtonaver-"
age of 220. Bremerton's av-
erage water use has been
dropping steadily since 1999,
when it was at 190 gpd. Rea-
sons for the lower usage in-
clude a large number of res-
idents classified as low-in-
come, higher-than-average
sewer rates and an active wa-
ter-conservation program,
according to the city's plan.
Cahall said she hopes that
the average consumption will
continue to decline as resi-
. dents living in older homes
replace their toilets and fix-
tures with low-flow models
and property owners switch
to low-water landscaping.
Meanwhile, the city Is ask-
ing the state for permission
to use existing wells needed
for future growth.
The idea of using Bremer-
ton's sewage effluent to water
Gold Mountain Golf Course
has been put on the back
burner, Cahall said. The cost
of pumping the water is a ma-
jor factor.
Also, it turns out that the
effluent contains a high con- .
centration of seawater, which
is not suitable for watering
grass. The seawater comes
into the system from ship-
yard operations and from in-
filtration into pipes along the
shoreline.
Bremerton plans to spend
$48 million over the next 20
years to improve piping and
storage, install an ultravio-
let treatment facility and deal"
with earthquake and security

SUMMARY: Water system planning is essential for the Bremerton Water Utility to meet forecasted
increases in water demands. The Water System Plan identifies present and future drinking water
needs and describes a means to meet those needs in a manner consistent with federal, state, and local
laws. State regulation (Washington Administrative Code 246-290) requires public water systems to
prepare a Water System Plan every six years. The2005 City ofBremerton Water System Plan
Update meets these requirements.

SUMMARY: Passage of the Municipal Water Law in 2003 provided water utilities with more
flexibility in the exercise of water rights while also establishing water use efficiency requirements. In
response, the Washington State Department of Health is developing regulations requiring the
governing body of water systems to establish water efficency goals by July 1,2007. These goals are
to be established through a public process in conjunction with the water system's
Water System Plan. Bremerton is developing its goals at this time to coordinate with the current
Water System Plan Update adoption.

City of Bremerton Interim Water Use Efficiency Plan
Introduction
The City of Bremerton owns and operates a Class A municipal water system serving
approximately 52,000 people. Bremerton also owns and operates a non-transient-non-
community water system with a non-resident population of about 400 people.
Additionally, Bremerton sells water to the Puget Sound Naval Shipyard, the Rocky Point
Water District, and the City of Port Orchard. Details of water system management are
described in the City of Bremerton Water System Plan (WSP).
In 2003, the Washington State Legislature passed the Municipal Water Supply - Water
Use Efficiency Requirements Act. The Department of Health is expected to adopt water
use efficiency regulations in late 2006. These regulations will require water systems to
prepare Water Use EfficiencyPlans (WUEP).
This WUEP for the City of Bremerton is "interim" to meet the requirements of the 2005
Water System Plan schedule but is being completed before the final requirements of the
regulations in WAC 246-290-800 through 850 take effect. The new regulations will
apply to WSPs submitted for approval after July 2007.
Water use efficiency is defined by the draft rule as "increasing water supply
efficiency and water demand efficiency to minimize water withdrawals and water use".
A WUEP documents the policies and activitie~ implemented to minimize supply and
demand inefficiencies and to reduce water withdrawals and water use.
The City of Bremerton has placed an increasing emphasis on water use efficiency
efforts since the early 1990's. The City has expanded its customer program and is
active in regional water use efficiency programs such as the Water Purveyors
Association of Kitsap County (WaterPAK) Water Conservation Task Force and the
Partnership for Water Conservation Puget Sound. Efficient water use benefits the
environment, public health, and economy by helping to improve water quality, maintain
aquatic ecosystems, and protecting water resources.
The draft WUEP requirements for systems serving more than 10,000 connections are:
. Describe the current WUEP
. Estimate the water saved the past six years
. Describe water use efficiency goals and document how they were set
. Describe all water use efficiency measures to be implemented in the next six
years, including schedule and budget
. Estimate projected water savings
. Describe how the water use efficiency program will be evaluated
. Evaluate water distribution system leakage
. Provide an assessment of the water that could be saved through implementation
of water use efficiency measures
City of Bremerton Interim Water Use Efficiency Plan
Page I
How Bremerton is meeting current water efficiency requirements and how new
requirements are planned to be addressed are described in this WUEP.
Current Water Use Efficiency Program
The City of Bremerton values the continued high quality and adequate supply of its
water resources. The City believes that customer education about water quantity and
quality creates awareness which results in improved water use habits. Water use
efficiency can be viewed as a resource, an alternative to developing new water supplies
to meet new water demands. The current objectives of the City of Bremerton Water
Use Efficiency Program are as follows:
. Maintain use per ERU below 195 gallons per day per single family residence (an
estimate of the average use per ERU in Western Washington in 220 gal/day.
. Keep Maximum Day Demand less than twice the Annual Average Day Demand
. Meter every source
. Meter all demands as practicable and provide an estimate for demands that
cannot be metered (such as for flushing and firefighting)
. Maintain the water system to prevent leaks and promptly repair all leaks that
occur and maintain the difference between volume of water produced and
metered water used below 8% on a 3-year average.
. Educate customers about their water sources and basic water supply principals
. Encourage a conservation ethic
. Provide tools for customers to reduce water use
. Increase customer awareness of water-use habits and the value of water
. Reduce system wide per-capita water consumption
e Improve system reliability
. Protect environmental resources
. Ensure water use efficiency prior to developing new sources of supply
Under the new requirements, prior to July 1, 2007, Bremerton will have to implement a
public process to have City Council set water efficiency goals considering:
. Historic water use efficiency performance
. Historic Water use efficiency investment
. Customer base demographics
. Regional climate variations
. Forecasted demand characteristics
. Water supply characteristics.
. System financial viability
. System reliability
. Affordability of water rates
Implementation of the objectives has the potential for water savings on both daily and
peak demand basis, thereby delaying the need to develop costly new resources and
City of Bremerton Interim Water Use Efficiency Plan
Page 2
avoid capital costs. Water use efficiency programs will also be required if a system will
be requesting additional water rights or will be applying for State Revolving Fund loans.
Under the new regulations, the City of Bremerton is required to implement the measures
for a large system (over 10,000 connections). The table below identifies the measures
required for both medium and large public water systems under the previous
recommendations. In addition to these measures; demand has also been reduced by
the 1992 Energy Policy Act which requires efficient plumbing features in new
construction.
Table 1 shows how Bremerton exceeds the recommended water use efficiency program
for public water systems (from "Conservation Planning Requirements" Washington
State Department of Health, March 1994).

Under the new regulations, Bremerton will have to implement or evaluate at least nine
water use efficiency measures.
Bremerton's current program exceeds this requirement as described in Table 3.
City of Bremerton Interim Water Use Efficiency Plan

Estimated Water Saved by Bremerton's WUEP over the Last Six Years
A good measure of water savings is to look at use per single family unit (also known as
an equivalent residential unit (ERU)). Bremerton's water use per ERU has been
dropping steadily as indicated in Figure 1. From 1999 - 2004 the use per ERU dropped
from 190 to 184 gallons per day, a 3.2 % decrease. Use per ERU dropped even more
in 2005 due to media attention to the drought.

Bremerton's average water use per ERU from 1999 - 2004 is only 183 gallons per day.
This figure is low compared to the estimated Western Washington average use per
ERU of 220 gallons per day and reflects several characteristics of Bremerton's system
including:
. Small lot size within the City limits
. A much higher percentage of rentals (60%) than the national average (40%)
. 49% of Bremerton's residents are classified as low income
. Much higher sewer rates than the state average

Water Use Efficiency Goal-setting
Water efficiency goals must:
. Describe measurable outcomes in terms of reduced or maintained water production
or usage.
. Be set in a public forum that provides opportunity for consumers to participate and
comment.
. Be reviewed by the City Council who will consider all comments received.
. Be updated every 6 years as part of the Water System Plan approval process.
Bremerton is already doing an excellent job with water efficiency but still has some room
to improve. Proposed goals were selected to maintain our conservation achievements,
be reasonable to attain, and be easily communicated to our customers.
The following water efficiency goals were proposed for Bremerton:
1. Maintain water use per single family household to below 195 gallons per
day on a three year average.
2. Keep maximum day demand less than twice the average day demand on
a three year average.
3. Maintain non-revenue water below 8% on a three year average.
Rationale for Goal Setting
A large portion of Bremerton's water conservation outreach is to residents and
homeowners. The amount of water used by single family households is calculated
annually and is shown in the chart below:

- Proposed Goal
-- Average W. WAUse
- Linear (No Drought Data)
The average use per single family household in Western Washington is 220 gallons per
day. Bremerton has seen a steady decline in use per household since 1994. The
proposed water efficiency goal of keeping single family household use below 195
gallons per day is 11 % less than the state average and indicates the City's dedication
to maintaining the conservation advances already made.
City of Bremerton Interim Water Use Efficiency Plan
Page 7
Another emphasis of Bremerton's conservation program is to reduce high demands in
the summer by encouraging residents and businesses to use water wisely outside such
as by using recycling car washes and landscaping with plants with lower water needs.
One way to measure increased water use in the summer is to compare the water used
on the peak day with the average amount of water used throughout the year as shown
in the graph below.

-- Ratio MDD to ADD -- Proposed Goal - Linear (No Drought Data)
Bremerton thinks that keeping this ratio below two is a reasonable way to evaluate our
outdoor conservation program. Future conservation outreach will continue to
emphasize prudent outdoor water habits.
In addition to our water customers being efficient with their water, the water system itself
has to be efficient. Bremerton carefully manages its water resources by tracking all the
water it uses through source meters, tracking customer use through individual meters,
ensuring main breaks are promptly detected and fixed, and being alert to other water
losses. Each year we compare the amount of water produced to the amount of water
sold to customers as shown in the chart below.

The new water efficiency regulations require that the amount of water lost through
system leaks be less than 10%. Bremerton proposes that the amount of water not
measured by customer meters ("non-revenue" water), which includes leaks, plus water
used for flushing, firefighting, and other non-metered uses be less than 8% each year.
This is more than 20% below the state standard which only addresses leaks.
Since Bremertoil is already doing very well in the area of efficient \'vater use, these
goals aim to maintain current water-wise actions by customers and the water system.
Bremerton also proposes that these goals be averaged over a 3-year period so that an
unusual circumstance in anyone year does not cause a goal to be unachieved.
Bremerton'sforum for public input to these conservation goals was multi-faceted. In
addition to the public process during City Council approval of the water system plan, a
survey and information was available at:
. the Water Utility billing counter at 3027 Olympus Drive,
. on the City's web page at www.ci.bremerton.wa.us , and
. a public meeting held for November 16,2006 at 100 Oyster Bay Drive from 6 to
7:30 pm.
City council reviewed the comments received and since no comments recommended a
change to the. proposed goals, the City of Bremerton City Council established these
goals by resolution on December 20, 2006.
Water Use Efficiency Measures Implementation and Evaluation
Table 3 provides the descriptions of components for the proposed water use efficiency
program necessary to meet the new regulations:
· Describe the water use efficiency measures being implemented
· Schedule when water use efficiency measures will be implemented
· Budget for the measures
· Estimate water savings projections by identifying a percentage saving goal
· Evaluation to measure the success of programs
This program will apply to the two water systems owned and managed by Bremerton -
the Main System (#08200R) and the West 517 Zone System (#082734), and to the
system Bremerton contract operates - the Rocky Point Water System (#02052E).
Bremerton's wholesale customers are responsible for developing and implementing
their own WUEPs.

Public Education
The following activities are the components of Bremerton's public education activities for
water efficiency:
City Website: The home page of the City's website has a special icon for a quick link
into the water resources section.
Bill Showinq Consumption Historv: Bremerton's water bills show the past years' water
consumption history in a table as cubic feet. The usage during the same period the
previous year is called out separately for easy comparison.
Annual Report: Each year Bremerton sends out an annual report as required by
regulations requiring a "consumer confidence report" be delivered to each customer
before July 151 each year. Bremerton includes conservation information in its annual
report.
Brochures: Bremerton has a wide variety of brochures and fact-sheets on many water
conservation topics including leak detection, water wise gardening, rain barrels, etc.
located in public places throughout the service area.
Give-awavs: A variety of give-aways remind customers about the importance of water
conservation such as: pens, pencils, magnets, and notepads with a conservation
message and phone numbers/web sites. Some give-aways actually help them
conserve such as rain gages, low flow shower heads, toilet testers, and toilet saver
bags.
Celebrate National Drinkinq Water Week: Activities include a proclamation by the
Mayor, displays at area libraries, conservation bucket give-away, and Bremerton Kitsap
Access Television water film fest.
Speakers Bureau: The City targets teachers, students and youth groups in various
programs. Bremerton provides classroom visits, video library and brochures about water
resources and conservation to schools in its service area. These educational
opportunities are advertised in the "Enviroguide: Environmental Education Resources in
Kitsap County", which has been provided to elementary, secondary, high school and
home-school educators throughout the county annually since 1998.
Theme Shows and Fairs:" The City has portable displays which are used at local theme
shows and fairs promoting the use of water efficient practices and devices, describing
the sources of drinking water and promoting efficient use of our remarkable water
resources. At some events, the display is accompanied by a staff member dressed in a
costume of Splash!, our waterdrop mascot. Additionally, the City assists with the annual
Kitsap Water Festival, which provides a day of water learning and fun to 1,000 41h grade
City of Bremerton Interim Water Use Efficiency Plan
Page II
students. At the event, the City provides displays and classroom sessions about water
resources and water conservation.
Water Purveyors Association of Kitsap (WaterPAK): Participate in WaterPAK
conservation task force and Water Conservation Coalition of Puget Sound (WCCPS):
These groups provide a presence at community events, PSAs in newspaper, radio, and
TV, and WCCPS has a website.
Puqet Sound Enerqy's (PSE) Powerful Choices Proqram: This yth grade classroom
program consists of 4 days with a focus on water, air, land, and energy. Bremerton pays
a portion of the costs of the program.
Indoor Residential
"Be a Leak seeker!" Campaiqn: Customers are encouraged to check for and fix leaks in
their home. Campaign is promoted through brochures, displays, and the WaterPAK
Kitsap County Fair booth.
Toilet Testers: Bremerton supplies toilet h3ak detectors at the front counter and at
special events.
Toilet Replacement Promotion: Customers with older toilets are encouraged to replace
them.
Indoor Kit Give-away: Indoor kits are handed out after having the customer sign a
pledge and allowing us to access their water use records.
Leak Notification: Should a customer's bill have unusual consumption, a letter and leak
brochure are sent.
Outdoor Residential and Commercial
Landscape Manaqement: The City sends a brochure annually in the spring to irrigation
customers to promote maintenance of irrigation systems and efficient watering
practices. In 1996 the City installed and has maintained a water conservation
demonstration garden at the public works and utilities facility. A brochure describing
waterwise gardening practices and a list of the plants is available at the billing office at
the facility. Bremerton has plans to provide area-specific ET information on the internet.
Rain Gaqe Give-away: Rain gages are distributed with information to encourage
waterwise gardening.
Demonstration Gardens: Demonstration gardens are located at the Utility's office at
Olympus Drive and at the Givens Center in Port Orchard. Other smaller "pocket"
gardens are being planned.
City of Bremerton Interim Water Use Efficiency Plan
Page 12
Rain Barrel Promotion: In 2001, Bremerton led a county-wide promotion on rain barrels
with 1,000 sold. Now the focus is to encourage customers to build or purchase their
own. The local Kitsap Lumber provides the kits at a reasonable cost.
Indoor Industrial, Commercial, Institutional
Coordinate with PSNS: PSNS is Bremerton's largest water consumer and uses about a
third of the water produced. They are currently proceeding with an in-depth water
conservation audit.
Regulatory
No Water Wastinq Ordinance: Bremerton Municipal Code 15.02.200 states, "Any
person or owner receiving water service shall not waste water, or allow it to be wasted,
by imperfect or leaking stops, valves, -pipes, closets, faucets, or other fixtures, or to use
the water for purposes other than those named in the application. Violation shall
constitute grounds for the discontinuation of water service. (Ord. 4309 92 (in part),
1991 )
Water Shortaqe Continqencv Plan: Last was implemented in 2001. Customers
responded appropriately and saved 18% of their previous summer's demands.
Conservation pricinq: Bremerton has a two-tiered water pricing structure to encourage
conservation.
Other Measures
Recvclinq/Reuse: Water reuse is the beneficial use of reclaimed wastewater treatment
plant effluent in compliance with Washington Departments of Ecology and Health
regulations. Bremerton currently uses reclaimed secondary wastewater effluent to
irrigate inside the wastewater treatment plant grounds and at a neighboring business.
Approximately 130 gpm is used for in-plant uses and an additional 120 gpm are used
for irrigation in the summer months for an annual total of 88 MG/year. A "Water Reuse
Feasibility Study" completed in 1998 identified the potential demands for and costs to
provide additional reclaimed water to potential users in the Bremerton area.
Bremerton's wastewater has higher than average saltwater from collection system
infiltration and Puget Sound Naval Shipyard inflow making reuse possibilities
challenging. A 2005 County-wide reuse study indicated that Bremerton had the least
potential for large:"scale reuse and recommendedgrantfunding be focused at other
locations with more feasible reuse opportunities. The City is currently evaluating the
next step to take in reuse.

Evaluation of Conservation Programs
Every communication effort can benefit from being evaluated. Evaluation can help a
current communication effort achieve its objective and make future efforts more
successful. Each strategy for Utility communications presented in Table 2 has
suggested methods for evaluation.
Evaluation methods Bremertpn currently employs include:
. Counting the number of brochures distributed. Are some brochures or topics more
popular than others? Are some distribution methods or locations more popular than
others?
. Track the number and kinds of customer phone calls received. What issues are
important to those who take the time to call?
. Track the number of visitors to a booth or at an event. Are some events more popular
than others?
. Review news reports in response to a news release or interview. Did press releases
generate the desired coverage? Was the information published what was intended?
Where in the paperwasthe article?
. Track City web site visits. Which pages are more popular?
. Track water use. Are customers responding to conservation methods? In the summer
of 2001 all customer classes (with the exception of PSNS) reduced water use an
average of 18% in response to extensive increase of customer outreach requesting a
voluntary 10% water reduction.
More involved evaluations can take the form of surveys. For a survey to be truly meaningful, it
needs to be performed on a random sample, with an adequate number of respondents,
containing appropriately-worded questions. Simple questionnaires can be used to get general
information as long as the results are used carefully.
The City has performed surveys as an integral part of some projects. In 1993 when the City
was required to perform customer tap sampling for compliance with the Federal Lead and
Copper Rule, a written survey was performed. Additionally, when customers received indoor
conservation kits for the technical study, a survey was performed. The surveys have assisted
the City with determining attitudes towards water use efficiency, service, cost and the optimum
methods to use to communicate with customers. The City will continue to perform surveys of
customers.
The City was the coordinator of a county-wide study to determine the effectiveness of single-
family indoor conservation kits. Over 2,000 kits were distributed countywide, with the City
distributing 650 kits. Water usage data of 140 customers before and after kit installation was
collected from seven participating water purveyors, including Bremerton. The study determined
that, on average, a 10% water savings was experienced by the study group during the winter
months. This study provided local. data to be used when promoting kits.

Water Distribution System Leakage Evaluation
The draft new water efficiency regulation requires that water distribution system leakage
may not exceed 10% of total water produced and purchased (using a rolling 3-year
average). Compliance will begin in 2010 and will be based on data from 2007 - 2009
(details may change when the regulation is finalized).
Leakage is defined as water loss from the system that is not metered and not used for
authorized purposes such as for flushing and fire-fighting.
Bremertonis a fully-metered system. All sources are metered and all pump stations are
metered to track flows in the distribution system. All customers are metered.
Bremerton also meters the fire training center and construction hydrant meters. There
are two locations in the service area to fill tanker trucks at no cost that are metered.
Each year Bremerton calculates the difference between gallons of source water
produced and metered water to customers. This difference has been called "non-
revenue water" and it includes authorized non-metered water such as for flushing and
firefighting as well as leaks and unauthorized water use. Non-revenue water for the
past 6 years is shown in Figure 2.

The average non-revenue water for Bremerton form 2000 - 2005 is 4.7% or
approximately 130 million gallons per year. Because this difference has been
consistently well-under the 10% standard for leaks, Bremerton is not required to have a
water loss control plan. The annual components of the non-revenue water are
estimated to be:

Future Reductions as a Result of Water Use Efficiency
Water demand is measured through the approximately 16,800 service meters located at
each customer's connection to the City:s system. All services are metered. Navy
contracted meters are read monthly and Water Utility personnel read the other
residential and commercial meters every other month. Average day demand for the five
years 1999 through 2004 is 7.7 MGD.
Maximum day demand (MOD) is defined as the highest amount of water used ih a
single day in the calendar year. This usually occurs in the summer as a result of
increased outdoor use. For Bremerton, this data is estimated using source production
meters. The ratio of MOD to ADD for the past five years range from 1.76 to 1.94 which
City of Bremerton Interim Water Use Efficiency Plan
Page 16
is in the expected range for Washington water systems. Forecasted MOD were
calculated using a peaking factor of 2.0.

Navy properties include the Puget Sound Naval.Shipyard (PSNS), Jackson Park
Housing complex, the Navy Hospital, and several other smaller accounts. The largest
demand in the entire system is PSNS which has a water demand of about 2 MGD.
Historically, the Navy has had a significant effect on Bremerton's water system. It was
due to increases in workload at PSNS and the resulting increase in Bremerton's
population that water demands skyrocketed during World War II. Within PSNS the
water uses are indListrial/commercial use (64%), shipboard use (18%), steam
production (13%), and residential use (5%).
There are approximately 1,400 non-residential water accounts in the Bremerton service
area consisting of commercial, government, and industrial entities. Other large non-
residential water users include the two area hospitals and the City's wastewater
treatment plant. The majority of businesses consist of office-based businesses,
restaurants, medical facilities, automotive shops, and services (dry cleaners, beauty
shops, etc.).
As the population grows and commercial/industrial development occurs, demands on
the water system will increase accordingly. Water systems are required to prepare two
forecasts: one forecast without conservation 'and'one forecast showing the expected
reduction from implementation of a water use efficiency program.
For the "without conservation" forecast, average day system demands were estimated
assuming a continuation of the existing residential per capita demand and using
population projections, and water use projections provided by the Navy and for planned
commercial/industrial development. Annual average demand projections were based
on the following approach:
. Residential demands for single family housing were calculated by increasing the
2004 residential demand of 2.63 MGD by the same percentage as the projected
population increases. Additional demands were reduced by 5% to account for
implementation of mandated reduced flow plumbing fixtures in new construction.
. Multi-family units forecasted demands were calculated the same way as single-
family units.
. The non-residential demands for commercial/industrial development was
calculated by increasing current demands by the same rate as population growth
and then adding the increased demands of proposed large developments to the
existing commercial/industrial demands.
. Demands for PSNS were expected to reduce from implementation of their
planned conservation program. Jackson Park Housing is built-out Demands for
the entire Navy contracted water use were estimated to be 2.34 MGD by 2019.
. Irrigation demands for custorners with separate irrigation meters were calculated
to increase at the same rate as the growth in commercial/industrial use.
A separate average day demand forecast was calculated "with conservation" taking
projected water use efficiency reductions into account as follows:
City of Bremerton Interim Water Use Efficiency Plan
Page 18
· Single family residential- reach 5% of accounts (approximately 700 units) each
year for the next 10 years and they reduce water consumption by an additional
10%. This includes reductions in both indoor and outdoor use. Since estimates
indicate Bremerton has previously reached 30% of customers, by the end of the
next ten years, 80% of single-family customers will have been reached and
influenced to conserve 5%.
· Multi-family residential- reach 5% of the units (approximately 300 units) each
year for the next 10 years and they reduce water use by 5%. Opportunities for
water use reduction are more limited with multi-family dwellers.
· Commercial - reach 5% of accounts (approximately 130 units) each year and
they reduce water use by 5%. This includes only indoor use.
· Irrigation - reach 5% of the irrigation accounts (approximately 10 accounts) each
year and they reduce use by 5%. In 2010 begin using reclaimed water at
Pendergast Park.
· Navy properties - reduce total water use by 10% over the 20-year planning
period.
· After 2010, focus water use efficiency efforts on preserving the water use
efficiency behavior of the 80% of the accounts previously reached. This
approach assumes that some customers will be resistant to water use efficiency
actions.

Annual Performance Reports
Beginning in 2008, Bremerton is required to develop annual water use efficiency reports
by July 1 and must send the reports to DOH, the consumers, and anyone who requests
them, and make the reports available to the public. Water use efficiency performance
reports must include:
· Total annual water production
· Annual water distribution system leakage totals
· A description of Bremerton's vvateruse efficiency goals, including a schedule for
achieving the goals and a narrative of progress toward achieving the goals
Bremerton plans to include this information in its annual consumer confidence report. A
template for this report is in the appendix to the WUEP.

Efficient water use benefits the environment, public health, and economy by helping to improve water quality, maintain
aquatic ecosystems, and protecting water resources. The City of Bremerton has emphasized water use efficiency efforts
since the early 1990's. The City has an extensive conservation program for customers and is active in regional water
use efficiency programs such as the Water Purveyors Association of Kitsap County Water and the Partnership for Water
Conservation Puget Sound.

RE: WATER SYSTEM PLAN CONSISTENCY STATEMENT CHECKLIST
Dear Linda and Geoff:
The City of Bremerton Water Utility is in the process of updating its Water System Plan. As we
discussed a few weeks ago, water systems are now required to obtain "consistency statements" from
the local governments in their service area. Although most of the Bremerton water service area is
within city limits, approximately 20% of our customers are in unincorporated Kitsap County.
Please fill out and sign the attached blue consistency statement and return to me before July 17,
2006. Included with this letter are draft sections of Bremerton's Water System Plan, a service area
map, and section of the Bremerton Municipal Code pertaining to water service. Also attached is
additional information on the consistency statement.
If you need additional information, please call me at 473-2315 or Karen Klocke, Department of Health
Planner, at 360-664-2999.
I appreciate your attention to this new requirement.
Sincerely,
Kathleen Cahall
Water Resources Manager

Consistency Statement Checklist
This checklist is intended to ensure consistency of water system planning documents with adopted local
comprehensive plans and development regulations. Each local planning jurisdiction in which the water utility
provides service will review the relevant water system planning information and provide a signed consistency
statement to the utility for submittal to the Department of Health. If the local planning agency will not respond,
the highest authority within the utility (chair of governing body, executive director of private companies,etc.)
must sign to verify consistency of the plan information.
Water System Name: City of Bremerton
CPWS ID: Main System 08200R

Plan Date: 2005
Planning Document Title: City of Bremerton Water System Plan
Local Planning Jurisdiction:
The retail service area, and any other areas not served by a separate public water
system, and land use identified in the WSP is consistent with the adopted
comprehensive plan and adopted development regulations and policies.
For WSPs only: The growth projection used to forecast water demand for the
retail service area is consistent with the adopted city/county's population growth
projections (and commercial development projection if applicable). If a different
growth projection was used, the alternative growth projection and methodology
proposed is acceptable based on explanation given.
For WSPs only: New potential large water users (that may have a significant
impact on the water system) that the city/county is aware of have been identified
in the WSP.

Information Prepared by the Washington State Department of Health:
Water System Planning Consistency
with Local Plans and Development Regulations
Background
Consistency with local plans has been part of the Drinking Water regulations (WAC 246-
290-100(4)(a)(iii)) since 1977. The Municipal Water Supply - Efficiency Requirements
Act, Chapter 5, Laws of 2003 (Mu,nicipal Water Law), further emphasized that the
Department of Health's (DOH) planning processes become more closely aligned with
local comprehensive plans and development regulations. Changes to the Water Code
(RCW 90.03.386) require consistency ofthe water utility's service area with local land
use plans, comprehensive plans, coordinated water system plans, watershed plans, and
development regulations. The new section added to the State Board of Health Code
(RCW 43.20) states that water service provided to new customers must be consistent with
local land use plans, comprehensive plans and development regulations.
Service Areas
The retail service area, and any other area not served by a separate public water system,
defined in a water system plan (WSP) or small water system management program
(SWSMP) depicts where a water system currently provides water service as well as
where it plans to provide water service in the future.
Demand Forecast
WSPs forecast the water demand a water utility expects to serve within the next six years
and 20-year planning horizons. Forecasting methodologies should be consistent with
local planning population growth projections for the service area described in the WSP.
If alternatives are used to project water demand, justification for the growth projection
and methodology must be provided in the WSP.
Demonstrating Consistency
Prior to WSP submittal to the DOH, water systems need to work with local goverriments
in whose jurisdiction they provide water service to ensure consistency. There will be two
acceptable approaches to demonstrate to the DOH that consistency has been achieved:
1. The local jurisdiction( s) verifies consistency and provides documentation to
DOH.
2. If a water utility has attempted to gain verification of consistency from the local
jurisdiction but the local jurisdiction has not responded within 60 days, the
highest authority within the water utility must provide documentation of
consistency to DOH.
DOH regional office planners may be able to help the utility make the appropriate
contacts at the local level to obtain consistency determination.

(including West 517 Zone, ID # 08273); ODW Project #06-0715
Dear Ms. Cahall;
Thank you for submitting the Water System Plan (WSP) for the City of Bremerton Water System
(City). The Office of Drinking Water (ODW) is encouraged by the accomplishments of the
water system in producing this WSP. Prior to approval, the following specific comments must
be addressed. Response to these comments should be received by this office prior to
January 16, 2007.
GENERAL COMl\1ENTS (response required)
WATER SYSTEM PLAN
1. Page 1-7. The first paragraph has a statement that reads "The State requirement is a
minimum of 0.2 mg/L at the entrance to the distribution system with detectable chlorine
residual throughout the distribution system." This requirement is applicable for groundwater
systems that chlorinate and not for surface water systems. The concentration required at the
entrance to the distribution system is system-specific, which is baSed on the contact time
calculations. In addition, ODW requires a detectable residual in the distribution system and
we recommend that the minimum concentration be maintained at 0.2 mglL. Please modify
or remove this indicated statement from the text in your revised WSP.
2. Page 2-19. Table 2-5 on page 2-19 does not clearly specify the units of the values that are
presented. Please modify the table to include clearly dermed units in your revised 'VSP.

3. Page 3-4. The Qi value for Well 16 in Table 3-2 is in,consistent with the values for Qi in
Tables 3-5 and 3-10. Please correct any discrepancies in these tables.
4. Page 3-13. The first footnote for Table 3-5. states, "1,2,3,4 - The existing water rights are
eit.1}er or both;" We do not understand t.hjs corrunent. Please explain this comment in your
revised WSP.
5. Pages 6-5 to 6-7. System Operation. Please describe specific set points for alarm
shutdowns and caIlouts, and submit this information in your revised WSP.
6. Pages 8-8 and 8-9. In the section titled "System Physical Capacity Analysis" there seems to
be two contradictory statements regarding the limiting factor for system capacity. On page
8-8 the statement is made that storage is the limiting factor and on page 8-9 the text indicates
that source capacity is the limiting factor. Please clarify this and update the text in your
revised WSP.
7. Pages 7-2 and 8-15. The fire flow hydraulic analysis was done by assigning 1,000 or 1,500
gpm (each for two bours) to nodes, depending on whether the area was residential or
commercial. However, on page 8-15 the text states that the fire flow requirements range
from 1,000 gpm (for 2 hours) to 5,000 gpm (for 4 hours). Please explain why the
maximum fire flow requirements were not included in the hydraulic modeling analysis.
8. Page 8-9. Please clarify how the storage values in Table 8-3 were derived from Tables
8-5,8:-6, and 8-12.
9. Page 8-9. Footnote #2, for Table 8-3, uses the term "firm yield for Qa". Please derme what
this term means.
10. Page 8-9. In table 8-3, the value for "Total Storage Capacity (East)" is less than the value for
"Equalizing Storage (East)". Please explain why the total storage is less than the
equalizing storage, which is one aspect of total storage.
11. Sections 8.4.6 and 8.4.7 both mention the West 517 Zone projected storage deficiency.
However, the capital improvement plan does not mention potential projects for adding
storage to the West 517 Zone. It is our understanding that the deficiency will occur when
developers build and that no specific projects have been defined. However, we recommend
including this in the eIP table in order to avoid submitting a water system plan amendment
when projects are submitted for review. Please revise your CIP and resubmit it with your
revised WSP.
12. Appendix for ODW checklists. On the Water System Submittal Form, you checked no to
number 16, the request for submittal exception. Yet you included the City ofBremerton's
Utilities Development and Construction Standards. If you wish to have the submittal
exception, please state so in your revised WSP and have the City Resolution signed and
dated.
13. Appendix for ODW checklists. The Municipal Water Law, Attaclunent 5- Program
Consistency Statement Checklist, was not submitted with the WSP. The Consistency
Statement Checklist must be completed, and signed and dated by the county planning office

control program for beaver. Please explain the details of this Program. Please include
this information in your revised WMP.
29. Section VII. Bremerton' s plans for addressing the requirements of L T2 SWTR are not
described in very much detail in Section VII of the WMP. However, Section 4.5.1 of the
WSP contains a detailed description ofBremerton's plans. In Section VII of the WMP,
please make a reference directing readers to Section 4.5.1 of the WSP if they would IiIce
to obtain detailed information about Bremerton's LT2 plans.
30. Section VII. Please describe, and locate on a map, the locations where raw water
cryptosporidium samples are taken. Please note that compliance with cryptosporidium
monitoring will be calculated using a running annual average of all samples collected.
Ecology has not sent review comments on the City's WSP. When Ecology's comment letter
arrives, we will send a copy to you under separate cover. Please remember that ODW's approval
of your WSP will not provide any guarantee, and should not be considered to provide any
