Central Kitsap Treatment Plant (CKTP) Celebrates Recent Upgrades6/11/2019

(Brownsville, WA) -  Kitsap County Public Works will host a special ribbon cutting ceremony celebrating recent upgrades at the Central Kitsap Treatment Plant on Wednesday, June 12, at 1:00 PM. The upgrades include new ultra-violet disinfection equipment to improve energy efficiency, and new dewatering centrifuges to provide redundancy in solids treatment.

Wastewater that leaves the treatment plant is disinfected with ultra-violet (UV) light before it is released into the Puget Sound. UV disinfection equipment that was installed at CKTP in 1997 was energy inefficient and maintenance was becoming an issue. The new UV system and computed energy savings qualify for $200K in grant funding from Puget Sound Energy after successful operation. The Department of Commerce provided $350K in grant funding to go towards the $3.8 million project.

Solids removed from the water go through a separate biological process to generate biosolids, which are then land applied in eastern Washington. A centrifuge is used to dewater the solids before they leave the plant. The $4.8 million in dewatering upgrades include two new centrifuges and replaces a single outdated centrifuge. The new equipment will improve efficiency and provide redundancy in solids handling.

Both projects were funded by Kitsap County, City of Poulsbo, and Naval Base Kitsap Keyport.

Central Kitsap Treatment Plant treats an average of 3.5 million gallons of wastewater per day and serves more than 50,000 people, including the City of Poulsbo, Keyport and Naval Base Kitsap-Bangor. Public tours are available for Kitsap County residents interested in the wastewater treatment process. Contact Kitsap1 at 360.337.5777 for more information.
