Water from the State Water Project is available through the San Bernardino Valley Municipal Water District, which provides backup water supply to the District. The San Bernardino Valley Municipal Water District provides water from the State Water Project to water agencies throughout the San Bernardino Valley. Imported water is available and used on an as-needed basis.
About 30 percent of State Water Project water is used for irrigation, mostly in the San Joaquin Valley. Approximately 70 percent is used for residential, municipal and industrial use, mainly in Southern California. Water from the State Water Project is more expensive than water that the District obtains locally due to wheeling charges and pumping costs. But having State Water Project water available for use during emergencies and drought situations provides security for the District. Customers are assured that the District will be able to provide water to them through most situations. |

The
State Water Project consists of 22 dams and reservoirs. The largest
storage reservoir, with a capacity of 3.5 million acre-feet is the
Oroville Dam in Northern California. From there, water flows south
to the Bay-Delta where the North and South Bay aqueducts serve San
Francisco Bay area communities. The 444-mile long Edmund G. Brown
California Aqueduct begins at the Delta Pumping Plant and parallels
Interstate 5 south to the Tehachapi Mountains. To cross the Tehachapi’s
into southern California, water is lifted by 2000 feet at the Robert
D. Edmonston Pumping Plant.
