About DWR - State Water Project

Carl Torgersen, Acting Deputy Director

The California State Water Project is a water storage and delivery system of reservoirs, aqueducts, powerplants and pumping plants. Its main purpose is to store water and distribute it to 29 urban and agricultural water suppliers in Northern California, the San Francisco Bay Area, the San Joaquin Valley, the Central Coast, and Southern California. Of the contracted water supply, 70 percent goes to urban users and 30 percent goes to agricultural users.

Provide timely, cost-effective, and quality engineering, geology, construction, real estate, geodetic, and administrative services to our clients in concert with Department of Water Resources' strategic goals and objectives.


State Water Project Analysis Office
This office administers policies and procedures to ensure that the State Water Project delivers water to the approximately 25 million Californians depending on it for at least a portion of their water needs. SWPAO is staffed with engineers, analysts, writers, and support staff. Our office has three main areas of management: Project Costs, Project Power, and Project Water. Within these areas we calculate contractor cost allocations, track the buying and selling of power, negotiate and administer water contracts, track water schedules and actual delivery amounts, prepare Bulletin 132 (Management of the California State Water Project) each year, and coordinate and approve new turnouts.
