The Carkeek Pump Station and combined sewer overflow (CSO) Treatment Facility is located within Carkeek Park (external link) in north Seattle. 

King County’s Carkeek facility was converted in 1986 from the Greenwood Sewer District Treatment Plant to a pump station, and later modified to include combined sewer overflow (CSO) control. Under most weather conditions, Carkeek pumps sewage flows to the West Point Treatment Plant for secondary treatment. During large storms, when flows exceed pumping capacity, wastewater is routed through the Carkeek treatment process and either stored for later conveyance or discharged to Puget Sound.
