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.

If you are planning to be away for an extended period of time, contact the District office to have the water shut off at the meter.
Inside your home you should, shut off your hot water heater (at the circuit breaker) and open a hot and cold water faucet in the house and one outside faucet to drain the water system and leave faucets open.
To protect outside faucets from freezing, cover them with some type of insulation.
Make sure to let us know if you will be gone for over six (6) months so we can note your account and in some cases, we can put your account under a “non-use” rate. In that situation we would need to have specific departure and return dates.
When you return, shut off all faucets and turn on the water at the meter. Open faucets one at a time to remove any air in the line. Turn the water back on in the house and check for any leaks by watching the water meter for movement.
