King County’s clean-water utility earns national environmental awards
‘Platinum Awards’ reflect outstanding record of permit compliance
An outstanding record of compliance with state and federal environmental permit requirements earned two prestigious awards from the National Association of Clean Water Agencies (NACWA) for King County’s clean-water agency.
The Wastewater Treatment Division’s South Treatment Plant in Renton and the West Point Treatment Plant in Seattle received Platinum Peak Performance awards for attaining 100 percent compliance with the effluent limits established by their respective National Pollutant Discharge Elimination System (NPDES) permit limits under the federal Clean Water Act and the state’s Water Pollution Control Law.
Platinum level awards indicate multiple consecutive years of compliance. To date, South Treatment Plant has attained 14 years of 100 percent permit compliance with its effluent limits, and West Point Treatment Plant has attained 10 years of compliance.
NACWA’s annual Peak Performance Awards honor public wastewater treatment facilities for their outstanding compliance records in the 2011 calendar year.
To comply with state and federal discharge permit effluent requirements, King County’s treatment plants must remove various pollutants from the wastewater in order to meet set limits for biochemical oxygen demand, total suspended solids, fecal coliform counts and total residual chlorine. The permit conditions also require each plant to conduct regular sampling and testing of both its untreated and treated wastewater.
Each day, King County’s two regional treatment plants treat and disinfect nearly 200 million gallons of wastewater for more than 1.5 million people in the greater Puget Sound region.
South Plant treats wastewater from east and south King County, southeast Snohomish County and northeast Pierce County.
West Point treats wastewater from Seattle, north King County and southwest Snohomish County.
