Welcome to Sammamish Plateau Water and Sewer District

The Sammamish Plateau Water and Sewer District provides water services to over 17,000 customers and sewer services to nearly 11,000 customers, and serves a total population base of over 54,000 residents. The 29 square mile service area includes the northern portion of the City of Issaquah, over half of the City of Sammamish and areas of unincorporated King County, including Klahanie. The District was formed by the vote of the people over 60 years ago, and continues to manage and protect its groundwater resources on behalf of the customers it serves.
