Overview of the District
Coal Creek Utility District is generally located between the cities of Renton and Bellevue, east of Lake Washington, and serves portions of the cities of Newcastle and Renton and a small portion of unincorporated King County. The District's water and sanitary sewer service areas are generally bounded on the north by the City of Bellevue city limits (Southeast 69th Street), on the south by the City of Renton and City of Newcastle city limits, on the west by Lake Washington, and on the east by Cougar Mountain Regional Wildland Park.
Our Water Sources
Two surface water sources provide all of the water for the CCUD system: the Cedar River and the South Fork of the Tolt River. These two river systems begin in the Cascades and have large protected watersheds.
Because they are publicly owned, Seattle Public Utilities can safeguard our water sources with a comprehensive watershed protection program that prohibits agricultural, industrial, recreational activities and human habitation. This means there is little opportunity for contaminants to enter the water. Even so, there is always some potential for natural sources of contamination.
Existing Water System
The approximately 5.7 square mile service area provides domestic potable water and fire protection service for over 3,600 customers. All water supply is obtained from the City of Seattle regional water supply system. (additional information is available in the ‘Links’ section of website) A total of five water storage reservoirs provide required standby, fire protection and equalizing storage. Four pump stations and eighteen pressure reducing valves are maintained to serve the customers in nine pressure zones.
Existing Sewer System
The approximately 4.9 square mile service area provides sanitary sewer service to over 2,900 connections. The District is divided into 11 drainage basins. The District maintains nine sewer lift stations that are used to pump wastewater flows where gravity service is not available. Coal Creek Utility District maintains an agreement with King County for wastewater conveyance, treatment and disposal.
