Your District

Soos Creek Water and Sewer District (SCWSD) has served the residents of southeast King County since 1939. We are a municipal corporation formed when Water District 58 and Cascade Sewer District merged in 1987.

In 1939 we began with a few hundred customers in an area of less than 2 square miles. We now provide water and sewer services to over 114,000 people living and working across 49 square miles.

Our water comes from Seattle Public Utilities via Lake Youngs, which is adjacent to the District's office. The District's sanitary sewer system conveys wastewater to King County's South Treatment Plant in Renton for treatment and disposal. 

SCWSD derives its authority from the Revised Code of Washington, Title 57, and is governed by a Board of Commissioners comprised of five publicly elected citizens living within the SCWSD service area.

The SCWSD Board of Commissioners, elected by the customers, has limited power to set policy within the framework of the state statutes, county and city ordinances.  SCWSD is not regulated by the state utility and transportation commission, which regulates private and investor-owned utilities.   

All actions of the Board take place in regularly scheduled open public meetings, which are held on the first, third and fourth Wednesday of each month at District headquarters at 4:30 p.m., or at specially scheduled public meetings. Customers are invited and encouraged to attend.
