Executive Summary The Sewer Division for Pierce County Public Works Department manages all activities involved with the collection, transmission, and treatment of wastewater produced within unincorporated Pierce County and several cities under interlocal agreements. The sewer service area consists of 117 square miles serving the cities of Lakewood, University Place, DuPont, Milton, and the unincorporated areas of Parkland, Spanaway, Midland, South Hill, Graham, Frederickson, Fife Heights, Brown’s and Dash Points, and the master planned communities of Sunrise and Tehaleh (Cascadia). The Sewer Division also provides contract services to the Town of Steilacoom and portions of the cities of Tacoma, Fife, and Edgewood. Since the founding of the original sewer service area in the 1970s, the Sewer Division has continued to protect water quality and public health, while facilitating significant growth and shaping economic vitality. The Sewer Improvement Program (Program) provides direction for the Sewer Utility including the Chambers Creek Regional Wastewater Treatment Plant and Collection System, a $1.8 billion dollar investment for Pierce County, and helps to ensure a reliable and seismically safe sewer system now and for generations to come. The Program also lays the groundwork for continued sewer system improvement projects to meet the changing demands of regulatory impacts, population growth and development, and infrastructure repair and replacement over a 20‐year planning horizon in accordance with the Washington State Growth Management Act (GMA). Population and employment projections are used to evaluate the system’s ability to meet future needs, and form the basis of recommendations for capacity expansion projects. The Program also addresses aging of infrastructure, system expansion, newly available analytical data, finances, revised forecasting of growth, and recommended improvements, serves as a basis for capital improvement planning for the next 20 years, and forecasts anticipated system build‐out needs based on land use zoning through 2037. The Program also identifies the costs of the improvement projects and provides a financial plan for funding the projects in coordination with the Capital Facilities Six‐Year Financing Plan.

Sewer Improvement Program 1 October 2016

Chapter 1 Introduction

Mission Statement The mission of the Sewer Division is to provide customers with high quality, cost effective sanitary sewer services by collecting and treating all wastewater generated from County service areas in accordance with applicable Local, State, and Federal permit requirements.

Purpose With the passage of Ordinance No. 2006‐115s the Pierce County Council required the Sewer Division of Public Works to combine the information found in the annual Pierce County Budget and the Capital Facilities Plan to produce an annual Sewer Improvement Program or SIP.

The SIP would then serve as a 20‐year central review document for the Sewer Division, County Council, their staff members, and the public to review the scope, cost, funding, and status of planned sewer improvement projects proposed to be undertaken by the Division. The SIP is a companion reference to the Capital Facilities Six‐Year Financing Plan. Budget proposals will continue to be part of the overall financial process, and the Capital Facilities Plan (CFP) will continue to be a part of the overall County six‐year projection as compiled by the Office of Budget and Finance under the Capital Facilities Six‐Year Financing Plan. The Sewer Division employs an asset management approach of “lowest life cycle cost” and “just in time” forecasting to identify needs and costs for collection and treatment improvements. Projects in the capital program are prioritized based upon commitment and need. Projects that are under contract have highest priority, followed by system needs and other opportunities. The SIP is utilized for long‐range planning and engineering of the county sewer system and of the Chambers Creek Regional Wastewater Treatment Plant. The Program is instrumental in securing long‐term funding and providing a dynamic platform for adjustment and revision to the CFP to best take advantage of new technologies and favorable construction opportunities. Together the CFP and SIP will continue to provide the direction for ongoing sewer system expansion and preservation.

Public Service ‐ strive for the best service for our customers, both internal and for the public using our systems and services;

Stewardship ‐ be responsible stewards of the assets and resources entrusted with us and of the environment we live and work within;

Organizational Structure The organizational structure of the Sewer Division is described below as it pertains to the administration, operation, and maintenance of the County’s sewer system. The sewer system is administered by the Sewer Division of Pierce County Public Works Department, whose overall management is provided by the Director and Deputy Director. In addition to general management duties, the director is responsible for reviewing regional and state legislative issues and for implementing policy. The director’s office is the primary point of contact for the County Executive and County Council. The County Council is the policy‐making body of Pierce County and consists of seven elected members. The County Executive, who is also elected, serves as chief executive officer. The Sewer Division is separated into four major sections:

Engineering The section manager for Engineering is responsible for management of project design, construction services and development review functions. The section oversees capital project design and management, conducts permit reviews, administers development processes requiring coordination with other County departments, and provides regulatory compliance and code enforcement. The section oversees staff at the Permit Counter, which is the first contact for customer service and information on development requests and approvals, and also conducts construction inspections to assure timely and efficient completion of projects, and ensure projects are installed and constructed according to approved design plans and specifications. Unless a specialized process requires the use of a consultant, design of projects is done primarily by the internal engineering section.

Maintenance and Operations The section manager for Maintenance and Operations manages the day‐to‐day operations and maintenance of the sewer system, including supervision of field crews, monitoring and assessing the condition of infrastructure to minimize system failures and maximize the life of system components, wastewater treatment plant operations, laboratory testing, and environmental compliance and reporting.


Organizational Services The section manager for Organizational Services is responsible for management of the sewer division administrative support functions, internal and external communication and outreach, business development and legislative efforts, emergency response and safety planning, water resources analysis, and biosolids coordination and management.

Planning and Programming The section manager for Planning and Programming manages the division’s financial portfolio including annual budget development and monitoring, rate forecasting, interlocal agreements and service contracts, grant and loan programs, and billing program support functions. This section oversees sewer systems long‐range plans, including the Unified Sewer Plan, Capital Facilities Plan, Sewer Improvement Program, sewer code regulations, and reviews and evaluates developer requests to determine long‐term effect on system operation. This section also coordinates capital project permitting, asset detail, hydraulic modeling, mapping, and property data management.

Sewer Service Framework

Improvement Types The Sewer Division strives to make every effort to improve services through five classes of improvement types: Maintenance: A project considered a routine activity associated with repairing a physical asset or keeping the physical asset functional during the asset's useful life. Maintenance of the wastewater treatment plant, collection system, pumps, and generators are examples of maintenance activities. Operations: Projects that include the costs and activities associated with the continued, highest, and best use of an asset. Public Works operations consist of all plant operations including collections, treatment, and fertilizer manufacturing. Providing public education on how to best use a system, responding to constituent requests and questions, and sewer billing are also regarded as activities associated with the efficient operations of a system. Preservation: Preservation is actually the replacement, or rehabilitation, of an asset after it has reached its useful life to accomplish the same overall function. These projects can be confused with the capital improvement of a system. Types of preservation projects for the Sewer Division can be: replacing a pump at a pump station, or replacing a failed pipe in a collections system. Improvement: This is a project that primarily improves the capacity or function of an asset. Any activity in the Capital Improvement Plan is considered an improvement activity. In Public Works the actions associated with the identification or development of the Capital Facilities Plan is considered an improvement activity. Administrative: These programs involve the management, planning, and coordination of the overall asset or asset group. Examples of administration activities include the management of boards or committees, planning activities such as basin planning or work on Environmental Impact Statements. Maintaining records and participation in department‐wide programs is also considered an administration activity.


Service Types The Sewer Division has two types of service areas: Urban and Rural. The Urban Service Area is the Sewer Division’s primary service area consisting of a 117 square mile sewer service basin consisting of 19 individual sub‐basins corresponding with the core of urban growth that has occurred around the City of Tacoma, in and around the Town of Steilacoom, and the cities of Lakewood, Fife, Milton, DuPont, and Puyallup. The service area also includes unincorporated areas of the County including Frederickson, Parkland, Spanaway, South Hill, Graham, Brown’s and Dash Points, Fife Heights, the planned community of Tehaleh (Cascadia), and a small area in the City of Edgewood. Covering 35 percent of urban Pierce County, this comprises the bulk of Pierce County’s sewer service area. The Rural Service Area was established prior to the adoption of the State Growth Management Act in 1994 and the Pierce County Comprehensive Plan in 1995. These areas were once under the designation of predominately General (G) or Suburban Residential (SR) and other less restrictive zoning designations that, prior to 1994/1995, allowed sewer connection. Once the Pierce County Comprehensive Plan was adopted in 1995 and re‐adopted and approved by Council in 2016, the Rural Service Area was and has remained restricted to parcels already served, and those parcels and projects that have vested connection rights. The Tacoma‐Pierce County Health Department also has the authority to require parcels in the rural zones and rural service area to connect to the public sewer system in the case of public health and welfare or environmental concerns. New connections not expressly vested through past land use decisions or Tacoma‐Pierce County Health Department connection requirements, are prohibited in any rural area.

Customers The Sewer Division’s customers or ratepayers are located in areas of unincorporated Pierce County within designated Urban Growth Areas, including Parkland, Spanaway, Midland, Frederickson, Graham, South Hill, Brown’s and Dash Points, Fife Heights, Tehaleh (Cascadia) and all or portions of the following towns and cities:

Town of Steilacoom

City of DuPont including the Historic Village and Northwest Landing City of University Place City of Lakewood including Tillicum and American Lake Gardens.

City of Tacoma (Western Slopes Service Area)

City of Milton (flows to the City of Tacoma's Central Wastewater Treatment Plant)

City of Fife (flows to the City of Tacoma's Central Wastewater Treatment Plant)

City of Edgewood (flows to the City of Tacoma’s Central Wastewater Treatment Plant)


CHAPTER 2

Systems Planning Considerations

Chapter 2 identifies physical features and sewer system facilities within Pierce County, and discusses their correlation and operation. Pierce County sewer system is entirely separate from the storm and surface water collection system. The wastewater system is well mapped, inspected, and maintained. There are no known connections between or conflicts with sources of water supply or storm water conveyance.

Land Use Land use within sewer service area is governed by the Pierce County Comprehensive Plan and various city comprehensive plans within the service area. The plan addresses current land use within the county and future land use direction. Land uses for future development of the service area were used in preparation of this plan. The density of development permitted in each land use designation throughout the entire sewer service area is specified in the zoning ordinances of the County and of other municipalities in the service area.

Sole Source Aquifer and Comprehensive Plan Requirements Much of Pierce County’s Urban Growth Area is located above a sole source aquifer. The installation of sewers and the continued decommissioning of individual septic systems in the urban zoned areas of the County aid in protecting this valuable resource. The 2015 Pierce County Comprehensive Plan Section 13 ‐ Utilities Element states goals to provide for the location of utility facilities and to insure adequate utility capacity for future growth. Further goals for sewer utilities are to provide sanitary sewers within the Urban Area and to utilize best construction methods and practices and innovative techniques in the design and construction of sewer utilities.

Pierce County requires the use of sewers in the County’s urban growth and urban zoned areas. To this end, collection system expansion is primarily accomplished by new development paying for the construction of new lines and connections to carry wastewater to the Chambers Creek Regional Wastewater Treatment Plant, Tacoma Central Wastewater Treatment Plant, and the Cascadia (Tehaleh) Large Onsite Septic System. The Sewer Improvement Program is utilized for a 20‐year planning cycle and is instrumental in securing long‐term funding and providing a dynamic platform for adjustment and revision to the Capital Facilities Plan to best take advantage of new technologies and favorable construction opportunities. The 2017‐2022 Capital Facilities Plan together with the 2017‐2037 Sewer Improvement Program will provide direction for the Sewer Division of Pierce County’s Public Works Department.


Level of Service The current Level of Service (LOS) of 220 gallons per day per residential equivalent meets current LOS requirements. This includes Chambers Creek Regional Wastewater Treatment Plant average daily treatment demand in 2014/2015 of 20.1MGD from an available operational capacity of 24.4MGD. Growth‐related and permit required reserves of 4.3MGD provide a total Plant capacity of 28.7MGD as shown in Table 2‐1. With substantial completion of Phase 1 of the Chambers Creek Regional Wastewater Treatment Plant Expansion project in December 2016, a re‐rating of the treatment capacities will be done in early to mid‐2017. At that time the maximum operational capacity and the capacity held in reserve will be revised to reflect these improvements. The new capacity rating will be approximately 43‐45MGD. The Sewer Division also owns 2.56MGD of capacity and treatment at the Tacoma Central Wastewater Treatment Plant located in the City of Tacoma at the Port of Tacoma. Flows from the cities of Milton and Edgewood and unincorporated Brown’s Point and Fife Heights areas are sent to this facility. Total available capacity from all locations including reserves within the Pierce County Sewer Service Area is 31.34MGD. Table 2‐1 summarizes the current capacities for all Sewer Division treatment facility locations. The two large on‐site septic or “LOSS” systems, listed in Table 2‐1 below, are stand‐alone installations for a specific single or multi‐customer use. These systems are the Cascadia LOSS at the Tehaleh Master Planned Development and the Etloh LOSS located on Fox Island.

The Cascadia LOSS (WWTP) system is currently rated at .1MGD. An interim WWTP is under review that will expand over time to become the Cascadia WWTP at Tehaleh, a 4.3MGD rated facility that will meet the wastewater treatment demands of the Tehaleh Master Planned Development through project build‐out.

The Etloh LOSS is a closed system that serves a small planned development on the south end of Fox Island. No new connections are anticipated to this system. Should additional connections be proposed, additional capacity would be required, and constructed, prior to any new connections.

Flow Projections Flow projections are generated using the Division’s flow modeling software and land use designations from the Pierce County Geographic Information System (GIS) using point flows for the service areas integrated into the flow projection model. The model then simulates the volume of wastewater that would be conveyed through the transmission pipelines to the treatment plant. Table 2‐2 presents a summary of the flow projections for the WWTP and conveyance system.

Table 2‐2

Summary of Flow Projections

Condition 1999 Actual 2010 Actual 2017 Projected

Average Dry Weather Flow 14MGD 18.9MGD 21MGD

Maximum Monthly Flow 22MGD 21MGD 23MGD

Peak Wet Weather Flow 44MGD 43MGD 43MGD Data derived from 2010/2012 Unified Sewer Plan

The model results suggest that the volume of wastewater flow at future service levels may be approximately two times greater than the volume of wastewater treated in 2010. The increase stems not only from the addition of new services, but also from development within the existing service area. Sewer service sub‐basins east of Interstate 5 have a number of medium sized undeveloped tracts for future development and also have large areas developed with on‐site septic drain field systems. Connection of existing development on on‐site septic drain field systems and future development will result in an increase in the volume of wastewater transmitted through the major conveyance facilities and treated at the Chambers Creek Facility. The projected average dry weather flow (ADWF) for 2016 is the same as was projected in the 2010/2012 Unified Sewer Plan Update. Future projected peak flows for 2037 of 109MGD are expected to exceed the capacity of the influent sewer pipeline to the WWTP of 104MGD and the capacity of the existing effluent outfall of 100MGD. However, improvements to these treatment plant related facilities will not be needed until the sewer service basin nears full development.

Conveyance and Treatment Wastewater conveyance and treatment services will continue for all basins in the existing sewer service area. The potential for new service for the Cities of Fircrest, Roy, and areas within DuPont, will be as requested by the individual cities. Table 2‐3 outlines a summary of the existing and possible service area components for the Chambers Creek facility.

In the event that the City of Fircrest chooses to transfer their wastewater flows from the Tacoma Central WWTP to the Chambers Creek Facility, infrastructure improvements must be made by the City to its collection system before these flows could be redirected. The City of DuPont including Northwest Landing continues to be provided the opportunity to send wastewater flows from the El Rancho Madrona and First Park sub‐divisions and from currently undeveloped property in the central and northwest areas of DuPont. Sewer service for the City of Roy can be accommodated within the existing collection system. The City would be required to secure funding for connection charges for the capital improvements to convey the wastewater to the Pierce County collection system. This would also require the City to complete, and have approved, a facility plan and project‐specific environmental review.


Chapter 3 CFP Projects 2017‐2022

Chapter 3 references and includes the projects for the current Capital Facilities Plan (CFP) as a part of the 2017‐2037 Sewer Improvement Program. Projects from the CFP have individual spreadsheets and location maps included to easily spot the project’s location within the sewer service basin. Information in these individual project breakdowns detail projected costs for Preliminary Engineering, Final Engineering, Permitting, Construction, Construction Engineering, and Miscellaneous or Other. Dollar estimates include a 4% annual inflation factor compounding over the six‐year cycle.

Sewer Improvement Categories Recommended sewer system improvements fall into eight general categories:

Chambers Creek Regional Wastewater Treatment Plant: These projects address known or potential system capacity expansion or reliability problems at the existing treatment plant.

Collections Improvement Projects: These projects address projected system capacity problems due to forecasted future development, and potential system capacity or reliability problems at the existing.

Collections Renovation and Rehabilitation Projects: These projects are intended to reduce the number and severity of system failures due to age in the collections system.

Miscellaneous Scoping and Feasibility Studies: Annual improvements that recommend improvement opportunities or feasibility studies to maintain, rehabilitate, and upgrade the Sewer Division assets.

WWTP and Collections Systems Repair and Replacement Projects: These projects and programs are intended to reduce the number and severity of system failures in the due to age at the WWTP.

Operations and Maintenance Projects: Projects recommended to maintain and increase efficiencies for operation of the Chambers Creek Regional Wastewater Treatment Plants existing infrastructure.

Chambers Creek Properties Projects: These projects are intended to improve the Chambers Creek Properties in conformance with the Chambers Creek Properties Master Site Plan, provide mitigation for current and future Chambers Creek Regional Wastewater Treatment Plant expansions, and to meet the requirements from the State of Washington, Department of Natural Resources, to reclaim the site from previous mining activities.

Environmental Services Building Projects: Projects recommended to maintain, rehabilitate, and upgrade the Sewer Division’s Environmental Services Building’s existing infrastructure.

Project Coordination The Sewer Division coordinates with the Transportation Division of Public Works for proposed infrastructure and maintenance projects each year. Projects are reviewed and coordinated with Transportation for the location of, or improvement to, new or existing sewer infrastructure. The Sewer Division’s Development Engineering Section will send copies of all proposed developer driven extensions after first review to the


Road Operations and Design sections to alert Transportation to upcoming developer sewer line extensions in the sewer service basin not associated with an adopted roads project.

Basis for Cost Estimates Cost estimates in this Program are planning level estimates and, as such, have been prepared without detailed engineering data. The cost estimates presented reflect the most probable capital cost. Actual project costs can be expected to vary in the future. Project cost estimates vary due to design changes made during preparation of final engineering plans and specifications, and as a result of changes in the cost of materials, labor, and equipment. Costs cited in this report are based on preliminary layouts of the proposed projects. The capital cost includes the estimated construction cost, state and local sales tax, and costs for administrative, engineering, financial and legal services and contingencies. Costs for land and easements are also included in this analysis. These costs are used in the Sewer Division’s financial model to generate long‐term financial forecasts and capital programming for the Sewer Utility.

Project Funding 2017‐2022 The County updates the 6‐year Capital Facilities Plan (CFP) and 20‐year Sewer Improvement Program (SIP) with detailed funding sources and project scheduling, every year. During each update, all proposed capital projects are evaluated against specific criteria and available resources, they are then prioritized, funded, and scheduled accordingly. Currently funded capital projects are presented in detailed project sheets below. Information, such as Project Fund and Identification, Scope, Purpose, Council District and Service Basin, can be found on theses individual project sheets. The project funding levels are consistent with those produced by the Pierce County Office of Budget and Finance. This information, in a less detailed format, is also found in the adopted 2017‐2022 CFP. Of the twenty‐seven (27) funded projects in the current Sewer Improvement Program, twenty‐three (23) are Sewer Division projects, two (2) are improvement projects for the Environmental Services Building, and two (2) are Chambers Creek Properties projects. Some projects do not have an individual project map due to their stature as system‐wide projects or an association with an existing Utility Local Improvement District. These projects include minor sewer line extensions, flow meter installations, and/or emergency generator replacements. Chart 3‐1 summarizes the six‐year capital project funding priorities by improvement category. The majority of capital spending is for Chambers Creek Regional Wastewater Treatment Plant (WWTP) projects through 2022, with a total of $38,434,100 budgeted for 2017 and 2022. With the completion of the WWTP Expansion Project scheduled for 2020, funding priorities begin to shift to Collections Improvement projects, Collection Renovation and Rehabilitation projects, and WWTP and Collections Systems Repair and Replacement projects.

Chambers Creek Regional WWTP: FMF Furnace Replacement 2017‐2018


Project Description: The furnace is an essential component in the Fertilizer Manufacturing Facility, without which it cannot operate. If inoperable, the Division is unable to produce Class A Exceptional Quality biosolids and would be required to haul and then land apply Class B biosolids using a contracted vendor, with anticipated costs of $20,000‐$25,000 per week in 2016 dollars. The recommended scope of work is to replace the furnace with a new, stainless steel furnace which will be less susceptible to corrosion than the existing steel unit. The balance of the work, estimated at $347,000, would be completed in 2017‐2018.

Chambers Creek Regional WWTP: FMF Digester Gas Delivery 2017‐2018


Project Description: The Fertilizer Manufacturing Facility was designed to utilize up to 60% digester gas that is readily available onsite through the digestion process. Utilizing this energy source has been hampered by inadequate system pressure, piping, and condensate removal, to allow the gas from the digestion system to be delivered properly. This project will install a new pressure boosting blower, install a new condensate removal system, and provide adjustments from the digesters to the FMF to allow digester gas use. This project is anticipated to save an estimated $100,000 annually on natural gas usage.

Basic information is provided in the form of a Project Number, Name, Type, Size and Length/Size of the improvement (if applicable) and estimated Cost. These projects are also included in Section 7 ‐ Future Expansion and Improvements ‐ of the Unified Sewer Plan. Dollar estimates are inflated for the proposed years of construction.

Sewer Sub‐Basin: Lakewood East and West including the Town of Steilacoom 2025‐2030 The City of Lakewood, excluding the areas known as American Lake Gardens and Tillicum, is located within Utility Local Improvement District (ULID) 73‐1. The City of Lakewood completed a sewer extension that has allowed both Tillicum and American Lake Gardens properties to connect to the sewer system. These two areas of Lakewood contain 968 single family and 1,124 multi‐family homes that in some cases will continue to be served by both individual and community on‐site sewer systems. With the sewer line extension, these flows began to be sent to the Chambers Creek Regional Wastewater Plant in late 2011. The total system service area is 11,041. The Lakewood West sub‐basin includes regional facilities serving both construction infill of the Lakewood West sub‐basin as well as facilities serving the DuPont Sub‐basin. No improvements are proposed in the Lakewood West sub‐basin.

The North Fork Trunk extends through a part of the Brookdale/Golden Given Sub‐Basin designated rural by the Pierce County Comprehensive Plan and connects urban growth area in the north part of the sub‐basin to the Brookdale Interceptor. New connections from rural zoned properties would not be permitted except in conformance with the policies of the Pierce County Comprehensive Plan or by direction of the Tacoma‐Pierce County Health Department.

Brookdale Trunk Proposed Construction Years 2027‐2030 This project, a 30” diameter 10,670 lineal foot line, will provide service to the eastern part of the Parkland area and the Woodland area of the East Basin. The pipeline will generally follow Waller Road between Brookdale Road and 112th Street East and will extend through a service area that is designated rural by the Pierce County Comprehensive Plan. The trunk will connect the urban growth area along SR‐512 to urban growth area on the south side of Brookdale Road. Connections of areas designated rural to the Brookdale Trunk will not be permitted except in conformance with Comprehensive Plan policies or by direction of the Tacoma‐Pierce County Health Department.


Brookdale Interceptor Expansion ‐ Proposed Construction Years 2031‐2035 The project, a 72” diameter expansion of the Brookdale Interceptor, will relieve future capacity constraints in the existing 54” Brookdale Interceptor. The expansion, a parallel pipeline or replacement/ enlargement, will extend approximately 16,003 lineal feet along the same corridor as the existing Brookdale Interceptor. It will connect the East Basin Interceptor in the East Basin Sub‐basin to the Parkland/Brookdale Interceptor in the Parkland Sub‐basin. The Brookdale Interceptor expansion will serve all sub‐basins upstream, including the East Basin, Rainier Terrace, and Frederickson Sub‐basins.

Military Road Interceptor ‐ Proposed Construction Years 2023‐2025 The project, a 15 to 18‐inch diameter, 3,750 lineal foot interceptor, follows Military Road from 32nd Avenue East to 22nd Avenue East. This project will provide sanitary sewer service between Military Road and 176th Street East.

Woodland Pump Station Permanent Force Main ‐ Proposed Construction Years 2029‐2031 The project, a 12” diameter 16,000 lineal foot force main, follows Woodland Avenue East north to SR‐512, then west along the southern edge of SR‐512’s right‐of‐way to Waller Road, then south on Waller Road to 112th Avenue East and then west to the future Brookdale Trunk. This project will connect the Woodland Pump Station to its permanent discharge point.


Sewer Sub‐Basin: Spanaway including the City of Roy 2027‐2035 The Spanaway Sub‐basin consists of approximately 4,859 acres, of which 1,767 acres is designated as Rural Service Area and is located in unincorporated Pierce County. The Spanaway Sub‐basin has six (6) proposed trunk and interceptor pipeline projects proposed for completion in years 2027 through 2035 and one (1) Pump Station project proposed for years 2033‐2035.

Spanaway Interceptor Phase 2 ‐ Proposed Construction Years 2027‐2030 The project will collect wastewater from the most southerly part of the Spanaway Sub‐basin and convey it to the B Street Interceptor via Spanaway Interceptor Phase 1. This 18”‐24” diameter 11,714 lineal foot interceptor will extend southwest down the Mountain Highway to approximately 224th Street East.

Muck ‐ Kapowsin Trunk ‐ Proposed Construction Years 2033‐2035 The project, a 15” diameter 2,115 lineal foot line, will provide service to a part of the Spanaway Sub‐basin that was designated rural by the Pierce County Comprehensive Plan. This line would not be constructed until either a sizeable number of on‐site sewer system failures occur that threaten water quality (pursuant to policies in the County Comprehensive Plan) or the area is incorporated into the County’s Urban Growth Area. The trunk will branch from the Spanaway Interceptor at 224th Street East and Mountain Highway and follow 224th Street East to approximately 35th Avenue Court East.

Elk Plain Force Main ‐ Proposed Construction Years 2033‐2035 The project, an 8” diameter, 1,800 lineal foot force main, will provide service to the Elk Plain Trunk line and will discharge into the Muck‐Kapowsin Trunk. The force main will be constructed at the same time as the Elk Plain Trunk line. The Elk Plain Force Main is a modification of the Elk Plain Trunk project.


Elk Plain Pump Station ‐ Proposed Construction Years 2033‐2035 This project is a modification of the Elk Plain Trunk project and when completed is expected to receive a peak flows of 1.0MGD transferring flows from the Elk Plain area through the Elk Plain Force Main to the Muck‐Kapowsin Trunk.

Elk Plain Trunk ‐ Proposed Construction Years 2033‐2035 The project, a 12” diameter, 3,877 lineal foot line, will provide service to the southern portion of the Chambers Creek Regional WWTP service area in the Spanaway Sub‐basin that was designated rural by the Pierce County Comprehensive Plan. The Elk Plain Trunk will drain into the Elk Plain Pump Station. Like the Muck ‐ Kapowsin Trunk, the Elk Plain Trunk would not be constructed until either a sizeable number of on‐site sewer system failures occur that threaten water quality (pursuant to policies in the County Comprehensive Plan) or when the area is incorporated into the County’s Urban Growth Area.


Sewer Sub‐Basin: Spanaway ‐ City of Roy ‐ 3rd Party Funding Sewer service for the City of Roy can be accommodated within the existing collection system should the City secure funding for connection charges for the capital improvements to convey the wastewater to the Pierce County collection system. This would also require the City to complete, and have approved, a facility plan and project‐specific environmental review. The City has three proposed infrastructure projects in addition to additional planning and environmental work that must be completed prior to connection to the Pierce County sewer system.

It would convey wastewater between local collection facilities and the Roy pump station. Preliminary costs for the interceptor assume 36” piping for the entire length.

Roy Force Main ‐ Project dependent on City of Roy Environmental Review and Funding The proposed Roy Force Main will be a 12” diameter line and extend 42,663 lineal feet and will be located generally along SR‐507, the Spanaway‐McKenna Highway. The force main will discharge into the County’s Wastewater Utility conveyance system in the Spanaway sub‐basin.

Roy Pump Station ‐ Project dependent on City of Roy Environmental Review and Funding The proposed Roy Pump Station is expected to receive a peak flow of 0.4MGD. This station will pump flow from the City of Roy through the Roy Force Main to Pierce County Wastewater Utility conveyance system facilities in the Spanaway Sub‐basin.


Sewer Sub‐Basin: Hylebos 2027‐2030 The Hylebos Sub‐basin is located within the City of Fife, the City of Milton, and unincorporated Pierce County. Seven parcels of the City of Edgewood are also included in this sub‐basin. This sub‐basin consists of approximately 4,824 acres. The Lakehaven Utility District connects to the Pierce County’s conveyance system at Porter Way within the City of Milton, where it is conveyed to the Tacoma Central WWTP for treatment. The Hylebos Sub‐basin has one (1) proposed trunk pipeline project, two (2) proposed pump station projects, and one (1) force main project proposed for completion in years 2027 through 2030.

Chapter 5 Developer Built Infrastructure Projects

Sewer Sub‐Basin: DuPont including Northwest Landing The City of DuPont is located in the southwest corner of the Basin. The Historic Village of DuPont was connected, and flows began to be sent to the WWTP, in 2008. The City has also contracted with Pierce County to provide sewer service to the Northwest Landing development (ULID 90‐4) and in October of 2000, the Northwest Landing Offsite Wastewater Facilities Project was completed and wastewater is now conveyed to the Chambers Creek Facility. Pierce County now provides for collection, transmission, and treatment for flows from the Northwest Landing Development (Villages I, II, III, IV, and V), Industry, Town Center, and the Historic Village of DuPont. The system service area is 3,727 acres in total area. The DuPont Sub‐basin has four (4) developer constructed projects proposed for completion as future development requires additional infrastructure. Developer built projects require review, construction, approval and acceptance by the Sewer Division prior to final connection to the sanitary sewer collection system.

Chapter 7 Financial

Financial Methodology The Sewer Division of Pierce County Public Works operates as an enterprise, essentially a business subsidiary of the County. As such, the Utility must operate within a budget constrained by rate revenues, connection charges for services, and maintain adequate reserves for contingencies. The Sewer Division uses a financial model to establish rates and connection charges to recover utility costs related to operational services and capital facilities that provide sewer service. Rates are set at a level sufficient to cover current and future expenses, and maintain reserves consistent with debt service requirements and long‐term financial forecasts. The model attempts to minimize the fiscal impact on the customer by assuming only enough debt to meet capital needs. The Sewer Division attempts to change rate levels gradually and uniformly to the extent that costs (including CIP transfers) can be forecast. Local and/or national inflation indices, such as the Consumer Price Index (CPI), are used as a basis for evaluating rate increases. Costs for services are passed directly through to Pierce County sewer customers. Each connected property bears an equitable share of the cost of the public sewer system through the collection of connection charges and rates for sewer service. Connection charges are paid before a property is allowed to connect to the public sewer system, or through a Utility Local Improvement District (ULID). Sewer rates are set by the County Council, and are in addition to connection charges. The Utility has established classifications of customers using rate charging methods authorized by State law in the Revised Code of Washington (RCW). Sewer rates are based on revenue requirements necessary to cover costs of the utility and are evaluated and authorized each year as part of the adoption of the annual budget. The Sewer Division’s financial strategy for developing the annual operating budget, forecasting capital investment, and determining revenue projections includes a detailed analysis of the following factors:

Utility objectives, policies, and standards for level of service, growth management, and land use constraints.

Debt service payments and debt service coverage/reserve requirements.

Capital assets including infrastructure, capital equipment, resources, and water rights.

Operations including labor and services, facilities, utilities, and supplies.

To ensure the Sewer Division continues to maintain a stable financial position, the capital and operating costs of the Utility are forecasted in the model through 2035.


Credit Worthiness Bond ratings from Moody’s Investors Service and Standard and Poor’s indicate a high level of confidence in the ability of the Utility to repay debt obligations. While the Sewer Division functions as a part of the overall County organization within the Public Works Department, the Utility operates independently for financial reporting purposes. This enables the Utility to issue bonds at more favorable interest rates by presenting its financial resources and revenue‐generating capability as related debt security. Bonds issued by the Utility have earned very positive evaluation of credit worthiness based on factors that include financial position, reserve levels, and debt service coverage. The Utility currently has a high grade bond rating of “Aa3” from Moody’s Investors Service and “AA” from Standard & Poor’s. Ratings at this level indicate a strong degree of confidence by the rating agency in the ability of the Sewer Division to repay related debt obligations. The Sewer Division has no immediate plans to issue additional debt. However, if this action becomes necessary, the Utility can expect a proposed bond issue to receive a similarly favorable credit rating and, therefore, to sell at lower interest rates than would otherwise be possible.

Current Financial Status The Sewer Division for Pierce County Public Works has a sound financial base that can finance the recommended capital improvements. The Sewer Division has adopted financial policies that guide the stewardship and investment of funds, use of debt, system expansion, connection and cost recovery, customer rates, and reserves for repair and rehabilitation. Table 7‐1 summarizes actual cash‐basis revenues, expenses, and fund balances for the sewer utility for the most recent five‐year period. Over the past five years, the sewer fund balance, which represents total unexpended resources carried forward to future years, increased from $91 million at the beginning of 2011 to a current balance of $101 million at the end of 2015 (See Chart 7‐1). During 2011 through 2015, a total of $534 million was spent on capital projects and service operations, including $52 million of debt service payments. The Utility plans for, and secures a reserve balance that covers 1.25 of debt service, and which includes 90‐days of annual operating budget.

Chapter 8 Sewer Division Public Programs

Over the past few years the Pierce County Council has requested that the Sewer Division investigate and produce various programs with the goals to assist both economic development and assistance to the individual ratepayers to expand and improve the sanitary sewer collection system. The following four programs either have been implemented, or are in final development, with the guidance of the Pierce County Council to achieve these goals. Of the four programs three, the Sewer Connection Program, the Sewer Commercial Conservation Loan Program, and the Impact Fee and Connection Charges Deferral Program, are active and available for use by the public. The fourth, the Sewer Residential Conservation Loan Program will undergo final program review by Council later in Quarter 4 of 2016 and, if approved by Council, will become available to the public in mid to late 2017.

Sewer Connection Program This program was established by Council in 2007, and has been utilized for a variety of projects both public and private. Program funds have been distributed along a value rating system acknowledging everything from acres served and jobs created, to economic development and health and safety improvements. The Program has funded various large sewer line extension projects sharing installation costs with local jurisdictions. Additional information pertaining to this program is available in the 2016‐2021 Sewer Improvement Program and on the Sewer Division’s website www.co.pierce.wa.us/sewer ‐ Plans, Reports, and Publications.

Sewer Commercial Conservation Loan Program This program has been established to provide loans of up to 90% of the estimated total cost for the installation of required sewer pretreatment facilities. Funding for these projects is available up to $50,000 for a term of up to 10 years. All loans are secured by a lien against the title of the commercial real property where the improvement exists and are subject to the Division's terms and conditions. Additional information pertaining to this program is available on the Sewer Division’s website www.co.pierce.wa.us/sewer ‐ Plans, Reports, and Publications.

Impact Fee and Connection Charges Deferral Program This program is designed to assist development and provide a mechanism that defers, but does not eliminate, fees paid for connection to the County’s sewer collection system. Additional information pertaining to this program is available on the Sewer Division’s website www.co.pierce.wa.us/sewer ‐ Plans, Reports, and Publications.


Sewer Residential Conservation Loan Program This program, requested by the Pierce County Council, is under review as a means to assist financially burdened rate payers with costly side sewer repairs, and prevention of side sewer breakdowns. The program would establish requirements and financing options for property owners to inspect, maintain, repair and/or replace sewer laterals, sewer relief valves, and sewer backwater valves as necessary on properties connected to the County’s sewer system. A residential program to keep side sewers in good repair is in the best interests of the health and welfare of the citizens of Pierce County. The Division looks forward to final program approvals in Quarter 4, 2016 and enactment of the program in 2017.

NOTICE: Notice of this request and date of this hearing were advertised in accordance with Pierce County Code and notice of the date and time of today’s hearing was published two (2) weeks prior to the hearing in the official County newspaper. REQUEST: Staff will not present a formal staff report to the Commission at this hearing, but a recommendation to the Commission for transmittal to the Pierce County Council to approve the Sewer Improvement Program as presented today. BACKGROUND: The Sewer Division prepares both a six‐year Capital Facilities Plan and a fourteen‐year Sewer Improvement Program, for use by both the County Council and public‐at‐large to understand the direction for maintenance, operations, preservation, improvement and administrative projects undertaken by the Division over a 20‐year time frame. The Capital Facilities Plan is part of the Budget and Finance Department annual budget process.

With the passage of Ordinance No. 2006‐115s the Pierce County Council required the Sewer Division to combine the information found in the Capital Facilities Plan and a fourteen year forecast to produce an annual 20‐year Sewer Improvement Program. This program serves as a review document for the County Council, their staff members, and the public to review the scope, cost, funding, and status of near term and future planned sewer improvement projects. STAFF RECOMMENDATION: Staff requests that the Planning Commission forward a recommendation of approval to the Pierce County Council for the 2017‐2037 Sewer Improvement Program as presented this day.


Appendix B ‐ CFP Project Expenditures and Funding Source Each project in the six‐year 2017‐2022 Capital Facilities Plan is now included as a single sheet project in Section 3 and is also included in a spreadsheet format here in Appendix B. This format details:

Project Specific Spreadsheet

New for 2017‐2037 are individual project maps for each project in the 2017‐2022 cycle reflected in Chapter 3 ‐ CFP Projects. This will provide Council, staff, and the public an easier document to review without going back and forth through the document to find information about single or multiple projects and then find a location map to identify where a specific project is in the sewer service basin. While this information duplicates that found in the Budget and Finance “Budget Book” the Sewer Improvement Program goes further to provide more detailed information pertaining to each project.

Appendix B provides an additional tool that brings all of the materials in Section 3 together in a shortened spreadsheet format for easy reference.



Appendix B ‐ 2017‐2022 CFP ‐ Project Expenditures and Funding Sources Project 1 ‐ Wastewater Treatment Plant Expansion Phase 1 ‐ Expansion Project An improvement project to expand the treatment capacity of the Plant, modernize the treatment process, and rehabilitate existing systems. It is the first of five phases approved by the City of University Place in February 2010 through Conditional Use Permit CUP09‐0001. The CUP consolidated all previous land use approvals for the WWTP into one new Conditional Use Permit using a Chambers Creek WWTP Overlay in what is now zoned as residential two or R2 zone classification. Completion of all five phases is not anticipated until 2040. Project 2 ‐ Wastewater Treatment Plant ‐ Reclaimed Water Pump Station An improvement project consisting of building a pump station, storage pond, and constructing piping to distribute reclaimed water to the irrigation system of the Chambers Creek Properties to irrigate the park features of the Chambers Creek Regional Park with the future intention of also irrigating the Chambers Bay Golf Course. Peak demands of up to 1‐2MGD in potable water savings may be realized with the availability of reclaimed water.

Project 5 ‐ Wastewater Treatment Plant ‐ Fertilizer Manufacturing Facility Furnace Replacement The furnace is an essential component in the FMF, without which it cannot operate. If inoperable, the Division is unable to produce Class A Exceptional Quality biosolids and would be required to haul and then land apply Class B biosolids using a contracted vendor, with anticipated costs of $20,000‐$25,000 per week. The recommended scope of work is to replace the furnace with a new, stainless steel furnace which will be less susceptible to corrosion than the existing steel unit. The balance of the work, estimated at $347,000, would be completed in 2017‐2018.

Project 6 ‐ Wastewater Treatment Plant ‐ Fertilizer Manufacturing Facility Gas Delivery The Fertilizer Manufacturing Facility (FMF) was designed to utilize up to 60% digester gas that is readily available onsite through the digestion process. Utilizing this energy source has been hampered by inadequate system pressure, piping, and condensate removal, to allow the gas from the digestion system to be delivered properly. This project will install a new pressure boosting blower, install a new condensate removal system, and provide adjustments from the digesters to the FMF to allow digester gas use. This project is anticipated to save an estimated $100,000 annually on natural gas usage.
