Fresh Water Supply for the Delta Region

The goal of the new alternative intake structure was to increase Contra Costa Water District’s (CCWD) ability to supply fresh water to its customers by avoiding seasonal fluctuations and degradation of water quality in the Sacramento Delta. The project was designed to provide state-of-the-art protection to the Delta fish, while simultaneously increasing the area’s water supply. The intake project serves as a redundant link in the District’s water supply chain and also fills Los Vaqueros Reservoir.

Psomas provided construction management support, inspection, and agency coordination services.

The three-phase project consisted of:

  • Phase 1: Victoria Canal Setback Levee – New setback levee and access roads
  • Phase 2: Victoria Canal Intake & Pump Station – New intake structure with pump station, state-of-the-art fish screen, equipment building, and other facilities, located in front of the new setback levee constructed in Phase 1
  • Phase 3: Victoria Canal Conveyance Pipeline – 12,000 feet of 72-inch pipeline to connect the new intake structure to the existing Old River Pump Station
