Westside WWTP Upgrades

Project Overview

The City of Bremerton (City) has identified six (6) significant treatment system components at the Westside Wastewater Treatment Plant (WWTP) that are at the end of their useful life and must be refurbished or replaced. The City has grouped the improvements into a single project to take advantage of design and construction efficiency, identified as the Westside Wastewater Treatment Plant Upgrade in the City’s 6-year Capital Improvement Plan (CIP).

The individual component improvements include:

• Centrifuge Replacement 
• Aeration Basin Supply Piping Replacement 
• Boiler System Reliability Improvements 
• Grit Chamber Rehabilitation 
• Headworks Screen Replacement
• Odor Control Stack Reinstallation 

Project Status

The City selected Kennedy-Jenks Consulting Engineers (KJ) to design the project. Although the City had been approved for a design and construction funding, the Department of Ecology modified the loan to be for planning and design only because the project was not far enough along in the planning process.

Kennedy Jenks is developing a proposal to complete the planning and design of the project but has been waiting for completion of the Comprehensive Plan. The Comprehensive Plan provides the base data necessary for planning information required by the Department of Ecology.

The City has decided to break out the Boiler System Reliability Improvements portion of the bundle of projects and advance the design while planning and designing of the other improvements progresses.
