Wet weather resiliency

We are continually working to make our operations more resilient during winter storms in wet weather season, and making improvements at our West Point Treatment Plant.

We currently have major projects underway to improve our wastewater treatment system, including:

Georgetown Wet Weather Treatment Station
Lake Hills and NW Lake Sammamish Sewer Upgrade
North Mercer Island/Enatai Sewer Upgrade
Ship Canal Water Quality (joint project with Seattle Public Utilities)

See how our system works:

The tragic loss of George Floyd, Breonna Taylor, Ahmaud Arbery and the grieving turmoil of their deaths has caused us great sadness and has strengthened our resolve to condemn violence against Black Americans.

King County Wastewater Treatment Division believes that the right to clean water and sanitation is a basic human right, as is life itself. We will keep working to end institutional racism in our organization and discrimination and bias in the communities we serve.
