WASTEWATER TREATMENT
Wasterwater treatment is a vital service provided by public works that helps keep our community healthy and our environment safe. The City’s recently upgraded wastewater treatment plant cleanses approximately 868 million gallons of water each year used for activates like washing dishes, bathing, and using the toilet. This prevents potentially harmful contaminants from entering local waterways like Goldsborough Creek, Shelton Creek, Oakland Bay, and Hammersley Inlet.

When water flows down a sink or toilet drain into the City’s sewer lines, it eventually ends up at the wastewater treatment plant for processing. During treatment, organic solids are extracted and the remaining wastewater is run through digesters with microorganisms that destroy most of the disease-causing bacteria. The wastewater then passes through powerful ultraviolet sterilizers that eliminate any remaining bacteria before it is safely returned to the environment.

The City of Shelton has historically taken extra precautions to ensure that the wastewater treatment plant exceeds the Washington State Department of Ecology testing standards. The City is sensitive to the nearby shellfish industry and the surrounding environment, and is committed to maintaining an elevated standard of performance. The City of Shelton’s wastewater treatment facility consistently earns an Outstanding Performance Award from the Department of Ecology.
