This Wastewater Treatment Plant is a regional facility designed to serve
the central area of Kitsap County. The facility began operating in 1979 as a
conventional activated sludge - secondary treatment facility. The treatment
plant provides sewage service for the cities of Silverdale, Keyport, and
Poulsbo, the Central Kitsap area, the Naval Submarine Base Bangor, and the
Naval Undersea Warfare Engineering Station at Keyport.
The effluent from the Central Kitsap Treatment Plant is discharged to Port
Orchard Bay, Puget Sound. The effluent is discharged approximately 3,200
feet offshore at a depth of 46 feet below mean low water. August 2007
Department of Ecology recognized this facility as an "Outstanding
Wastewater Treatment Plant" for 2006.
