Our Source of Water
Silver Lake Water and Sewer District's water comes from a large freshwater lake known as Spada Reservoir, located about 30 miles east of Everett, Washington.
It serves as the primary source of high quality drinking water for the majority of Snohomish County.
Spada Reservoir is part of the Upper Sultan River Watershed, an area emcompassing more than 80 square miles that represents one of the wettest watersheds in the continental United States, with an average annual rainfall of approximately 165 inches.

Our Water Quality
Water quality begins at the source: the Sultan Basin is carefully monitored, the watershed is patrolled, and human activities are limited to minimize the impact on the naturally pristine water.
From the lake, water travels to the City of Everett's water treatment plant, where it undergoes coagulation, flocculation, filtration and disinfection, before being distributed to the Clearview Water Supply Agency, of which Silver Lake Water and Sewer District is one of three members.
While Silver Lake Water and Sewer District still purchases some of our water from the City of Everett, the majority is supplied by Clearview.
