Eastside Treatment Plant UV Replacement

Project Overview

The Eastside Treatment Plant (East Plant) processes combined sewer flows from East Bremerton during wet weather periods when the volume of combined sewage exceeds the capacity of the downstream sewage conveyance system. Constructed in 2001, the UV disinfection equipment has reached its useful life and is no longer reliable due to becoming obsolete since replacement parts are no longer manufactured.  This project replaces the old equipment with new, more efficient, and reliable equipment. The purpose of this project is to upgrade the disinfection equipment.  The benefits of this project are the protection of water quality from the discharge of untreated combined sewer.

Project Status

This project is being delivered under a traditional design-bid-build approach. The City selected CONSOR to complete the final design. The City  has submitted a request to pre-purchase the UV equipment to the Department of Ecology. The City plans on placing an order for the equipment in November 2025. While the equipment is being manufactured and delivered, Consor wll be finalizing the bid-ready plans and specifications for bidding and award of a construction contract in May, 2026.

Although construction is planned for the Summer of 2026, project design review and approvals through the Department of Ecology could delay construction until the summer of 2027.
