District Offices

What We Are -- Who We Serve
Skyway Water & Sewer District is a Special Purpose District located in the West Hill area of unincorporated King County. The West Hill area includes the neighborhoods of Bryn Mawr, Campbell Hill, Earlington, Hilltop, Lakeridge, Panorama View, Skycrest and Skyway. The District shares service boundaries with the cities of Renton, Tukwila, Seattle, and King County Water District #125. Skyway's service area is approximately 1.8 square miles for water (serving 3,400 customers) and 2.7 square miles for sewer (serving 4,100 customers). The District maintains approximately 40 miles of water mains and 48 miles of sewer system piping.

How We Operate
As a local municipality, Skyway operates under the authority of Title 57 of the Revised Code of Washington. The District is subject to Federal, State and Local regulations. Three local citizens are elected to Skyway's Board of Commissioners by voters living within the District's Boundaries. The Board of Commissioners establishes District water and sewer rates, sets policies, and oversees operations. The Board meets regularly on the second and fourth Tuesday of each month at 6:00 p.m. All meetings are open to the public. Day to day District administrative and operational duties are carried out by a ten-member staff along with consulting engineers and counsel.

Frequently Asked Questions:
How do I find buried utility lines?

To protect property and prevent personal injury, Washington State Law (RCW 19.122) requires that you notify the Underground Utilities Locating Center (UULC) at 811 or 1-800-424-5555 if you are planning to dig a depth of 12-inches or more. Under state law, if you fail to call before you dig and damage any utility lines as a result, you may have to pay a fine of up to three times the cost of repairing the lines. You must call at least two business days before you dig. UULC will obtain information from you regarding your location and project. They will then notify Skyway Water & Sewer District and other utilities in the area. District field staff and/or other utility representatives will come out to your site and mark the location of the underground lines for you, free of charge. Once the site has been marked or you have been notified that the utility has nothing at your dig site, you can begin to dig safely.
