What We Are -- Who We Serve

King County Water District #90 (KCWD90) is a Special Purpose District located in the Renton Highlands area of unincorporated King County. The District’s Water Service Area is presently bounded on the west by the City of Renton. Coal Creek Utility District (CCUD) is adjacent to the northwesterly corner of the District’s Water Service Area. To the south, the Cedar River is the boundary between the District and Cedar River Water & Sewer District (CRWSD). Other adjacent water purveyors include the City of Issaquah to the northeast and Mirrormont to the east of the District. The District shares no boundaries with either of these purveyors.

How We Operate
The District is a municipal corporation as set forth in the Revised Code of Washington (RCW) Title 57 and authorized by King County ordinances. The District is subject to Federal, State and Local regulations. Three local citizens are elected to KCWD90’s Board of Commissioners by voters living within the District's Boundaries. The Board of Commissioners establishes District water rates, sets policies, and oversees operations. The Board meets regularly on the first and third Tuesday of each month at 4:30 p.m. All meetings are open to the public. Day-to-day District administrative and operational duties are carried out by a thirteen-member staff, along with consulting engineers and counsel.
