Document Description
The State Water Resources Control Board (State Water Board) is a Responsible Agency for the Project. The State Water Board’s Drinking Water State Revolving Fund (SRF) Program is financing the Project. The Project (which is a component of the Lower Reach River Supply Conduit (RSC) Project) includes construction of the western segment of RSC Unit 1A, where a new flow control station will be located. The western segment of Unit 1A will join the previously installed eastern segment of Unit 1A, southwest of Headworks Reservoir East, and extend westerly to join the future Upper Reach RSC Unit 7 at the western end of the Headworks property. The western segment of Unit 1A will be located within a proposed 20-foot-wide paved internal access road, approximately 100 feet north of the Headworks property southern boundary fence, and consist of approximately 2,000-feet of 78-inch diameter pipeline installed via open trench construction methods. The flow control station will be built underground inside a vault, with approximate dimensions of 45-feet by 25-feet, within the Headworks Spreading Grounds site. This station will consist of approximately five smaller pipe legs (two 30-inch and three 20-inch legs). Each pipeline will have a control valve, which would be operated as necessary to maintain the pressure requirements downstream within the Lower Reach RSC pipeline. The proposed location of the station is at the site of an existing paved construction administration area in the western part of the Headworks property.
