Wastewater
Bremerton's sewage system provides sewer service to approximately 37,000 people. The wastewater collection system serves City residents as well as nearby areas in unincorporated Kitsap County.The City of Bremerton's wastewater collection system consists of 188 miles of combined and sanitary sewer mains, 14 combined sewer overflow outfalls, 35 liftstations, approximately 16 miles of force mains, 6 odor control stations, 6 flow monitoring stations (for billing purposes) and 2 composite sampling stations. The city's wastewater treatment plant has an average annual flow of 7.6 mgd and a hydraulic peak capacity of 32 mgd. Treated effluent from the wastewater treatment plant discharges into the Sinclair inlet.
The older portions of the Bremerton sewer system were constructed as combined sewers (sewers that collect both stormwater and wastewater) which was a common and accepted practice at the time. The sewers originally discharged to the receiving waters without treatment and consequently there was no need to construct separate systems. Thankfully the practice of constructing combined sewers has been prohibited for many years. The current sewer construction practice is to install separate sanitary and storm sewers.
