Wastewater Comprehensive Plan Update

Last Content Update:

Project Overview

The City updates their general sewer plan typically every 10 years as required by the WAC 173-249-050.  The plan is a guidance document that provides a comprehensive overview of the entire wastewater system. Additionally, the plan forecasts the improvements necessary to maintain the system over the next 20 years based on changing system flows and loading that are affected by growth, aging infrastructure and legislation. Contents include a system overview and inventory, development of hydraulic models to evaluate collection system and wastewater treatment plants, impact of regulatory requirements on system operation, description of the services areas and basins, evaluation of flows and loads to the plant as well as treatment performance, risk evaluation, development of a 20-year capital improvement program, evaluation of and recommendations to improve operations and maintenance, and a financial analysis to determine the impact on sewer rates for the proposed capital improvements. The finished plan is presented to the City Council for consideration and approval. The plan was last updated in 2014.

In addition to updating the general sewer plan, the City’s engineering consultant (Kennedy Jenks) will evaluate the following items: 1) The Crosstown pipeline, a major trunk sewer through downtown Bremerton which carries all the flow from East Bremerton and a significant portion of the flow from West Bremerton, to the WWTP. This critical pipeline will be evaluated for redundancy to determine if an additional pipeline is required and associated costs. 2) Considering alternatives for providing sewer service for the Puget Sound Industrial Center (PSIC). 

Project Status (June 2025)

The draft WWCP Update prepared by Kennedy Jenks was submitted to the City on February 18, 2025.  The public comment period for the draft ended in March 2025.  The draft is currently being reviewed by the Dept. of Ecology.  The draft and SEPA checklist were submitted to the Department of Community Development for review at the end of May 2025, with the two week SEPA public comment period anticipated to start in early-to-mid June.   Adoption of the plan by City Council is anticipated in late summer 2025.
