Kitsap County General Sewer Plan Update: Kingston Service Area

2.2 Kitsap County Sewer Utility Division

Since the 1950s, the Kitsap County Sewer Utility has operated and maintained a wastewater

collection and treatment system serving communities across the Kitsap Peninsula. The system

includes gravity pipelines, force mains, manholes, inverted siphons, and pump stations that convey

wastewater to the regional treatment facility, the Central Kitsap Treatment Plant (CKTP). In addition

to treating wastewater from its primary service area, CKTP also processes solids from the

Manchester, Kingston, and Suquamish Wastewater Treatment Plants.

2.3 Kingston Wastewater Treatment Plant

The Kingston Wastewater Treatment Plant (KTP) is located north of CKTP, in Kingston, Washington.

KTP holds a monthly flow capacity rating of 0.292 MGD. The KTP collection system includes

approximately 57,400 feet of gravity pipe and 26,000 feet of force main piping. Approximately 1,000

feet of pipe within the system is privately owned. Additionally, there are seven pump stations within

the Kingston sewer system, including PS-41, 42, 43, 52, 71, 72, and 73. The pump station capacity

ranges from 20 gallons per minute (GPM) at PS-52 to 450 GPM at PS-71. All sewer flows within the

basin are conveyed and treated at KTP. The treated effluent from KTP is conveyed and discharged

to Appletree Cove.

While previous planning efforts provide an overview of the system, they do not fully evaluate long-

term treatment capacity needs or identify specific improvements required to accommodate projected

growth within the Kingston service area. Given anticipated population growth and development

pressures, there is a need to assess the existing capacity and performance of the Kingston

Wastewater Treatment Plant and its associated collection system.

In response, Kitsap County proposes this Request for Qualifications (RFQ) to prepare an amendment

to the Kitsap County General Sewer Plan for the Kingston Service Area. This effort will include a

comprehensive evaluation of existing conditions, with particular emphasis on identifying potential

capacity limitations and operational constraints at the Kingston Wastewater Treatment Plant. The

analysis will also project future wastewater flows and assess the ability of the treatment plant and

collection system to accommodate anticipated growth. Based on these findings, the amendment will

identify facility improvements necessary to address capacity constraints, ensure reliable operations,

and maintain compliance with applicable regulatory requirements.

2.4 Project Schedule

This contract and the scope of work in Section 3 is envisioned to be completed within a 2-Year

timeframe once formally awarded, with the option to extend for an additional 3-Years.

2.5 RFQ Intent

The intention of this RFQ is to solicit qualifications from a Professional Consulting Firm to assist the

Owner in preparing an amendment to the Kitsap County General Sewer Plan. The selected firm will

review the Kitsap County Comprehensive Plan and General Sewer Plan, evaluate existing

wastewater treatment facilities, and develop population and wastewater flow projections for the

Kingston service area. This effort is intended to improve the Owner’s understanding of current

treatment capacity, projected wastewater demand, and any required facility improvements. The

outcome of this engagement will be an amendment to the General Sewer Plan documenting existing

system capacity, projected wastewater flows, and recommended improvements to support future

growth and development within the Kingston service area. Section 3 provides a preliminary

description of the intended scope of work and deliverables to be incorporated into the contract once

awarded.

• Develop population and wastewater flow projections for the Kingston service area based on

adopted land use assumptions and planning horizons.

• Estimate future treatment capacity needs (MGD) and identify timing for when additional capacity

will be required.

• Identify and evaluate facility improvement alternatives to address projected growth, maintain

regulatory compliance, and support reliable long-term plant operations.
