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:
Why am I billed for Capacity Charge?

The sewer charges on your Skyway bill are for maintenance of the District's sewer lines and for treatment and disposal at King County Wastewater Treatment facilities. To keep up with growth, protect public health and the environment, King County must expand its infrastructure by building more pipes, pump stations, and treatment plants. Capacity charge helps evenly spread these costs and ensures that "growth pays for growth". In addition to your Skyway bill, customers who connected to the sewer after February 1, 1990 are billed by King County for capacity charge.
