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.
Section 3. Professional Services

will be required.
• Identify and evaluate facility improvement alternatives to address projected growth, maintain
regulatory compliance, and support reliable long-term plant operations.
