District Overview

MISSION STATEMENT: Meeting the challenge of protecting the environment and providing quality sewer service to the community

The District is located in Snohomish county, Washington (the "County"), and approximately six miles east of the City of Everett and 30 miles northeast of the City of Seattle.  The District was established in 1957 and has provided sanitary sewer service, both collection and treatment, since 1965.

In 2005, the District entered into the Unified Sewer Agreement with the City to operate and maintain all sewer collection and treatment facilities within the entire Lake Stevens Urban Growth Area ("UGA"), both unincorporated area and the City.

The District currently operates 125 miles of collection system, 12 miles of interceptor and 31 lift stations and the treatment plant is located adjacent to 9th Street SE and Sunnyside Boulevard, above the Snohomish River floodplain. The new Sunnyside Treatment Plant facility provides exceptional waste water treatment and disposal to the District's service area through 2028, with provisions for upgrades to serve build-out conditions.  Tours are available upon request.
