Service Overview


Your Water

Water for the Olympic View system is sourced from the South Fork Tolt River Watershed, located on the western hills of the North Cascade mountains in east King County.  This area receives between 90 to 160 inches of precipitation each year, which produces approximately 100 million gallons of drinking water per day.  The District also owns and operates its own water treatment plant tied to the Deer Creek system which handles 0.6 million gallons of water a day.

Treatment of the South Fork

Before entering the main supply lines, water from the South Fork Tolt River Watershed passes through a screen house to filter out debris, and then through an innovative filtration plant that uses ozone to disinfect the water and carbon filters to remove particulate matter. Lastly, water is treated to provide ongoing disinfection, fluoridation, and corrosion control.

Your Sewer

The District is also responsible for 24×7 operations and maintenance of a sanitary sewage collection system throughout a nearly identical service area.

Saving Water Partnership

The District is proud to be a part of a group of local water utilities in Seattle and King County who are working together to help customers save water and money. Known as the Saving Water Partnership, we are working to implement a 1% Water Conservation Initiative: to reduce personal and business water consumption 1% every year for ten years.
