Water Sources

LOCAL GROUNDWATER

About half of the Santa Clarita Valley’s (SCV) water is produced by the local groundwater. The groundwater supplies in the Valley come from two sources: the Alluvium Aquifer and the Saugus Formation. The Alluvium Aquifer generally underlies the Santa Clara River and its tributaries to maximum depths of about 200 feet; the Saugus Formation underlies practically the entire Upper Santa Clara River area to depths of at least 2,000 feet.

THE STATE WATER PROJECT

About half of the SCV’s water is imported, primarily through the State Water Project, which extends for more than 600 miles from north to south terminating at Castaic Lake.

Water is first stored in Lake Oroville, located northeast of Sacramento. At Oroville Dam, water flows through three power plants, then down the Feather and Sacramento Rivers before reaching the Sacramento-San Joaquin Delta.

The Sacramento-San Joaquin Delta is a complex network of natural and man-made channels at the confluence of the Sacramento and San Joaquin rivers near the cities of Sacramento and Stockton. Water makes its way through the Delta to the Harvey O. Banks Pumping Plant where it begins its journey over 300 miles south in the California Aqueduct.

At the A.D. Edmonston Pumping Plant the water is lifted 1,926 feet and enters eight and a half miles of tunnels to cross the Tehachapi Mountains. From this point the water continues south through the West Branch of the California Aqueduct through Quail Lake, Pyramid Lake and finally into Castaic Lake.

Water is withdrawn from Castaic Lake and flows through large underground pipelines to supply the Agency’s treatment plants, the Earl Schmidt Filtration Plant and the Rio Vista Water Treatment Plant.

Recycled Water

Recycled water has been available in the Santa Clarita Valley since 2003. The use of recycled water extends our drinking water supplies, reduces our reliance on costly imported water supplies and enhances our water supply reliability. Currently, an average of 475 Acre-Feet per Year (AFY) of recycled water are delivered to the Valencia Water Division. The Valencia Water Division delivers recycled water to irrigation, including a golf course and street medians.

The recycled water distribution system uses completely separate pipelines from the domestic drinking water system and is denoted by purple pipes, purple color-coded irrigation systems, and signage.

In the next few years, SCV Water is proposing to expand the use of recycled water to additional users throughout the Santa Clarita Valley.

BANKING & EXCHANGE PROGRAMS

SCV Water uses banking and exchange programs in order to increase the water supply reliability. Banking and exchange programs involve storing water in the ground for use in future times of need. Many of these programs are located in Kern County.

Urban Water Management Plan

The Urban Water Management Plan (UWMP) presents a picture of the valley’s water situation through the year 2050, describes the long-range water needs of the community and the means to supply the necessary water. The UWMP was adopted on Wednesday, June 8, 2016.

SCV Water Report

The Santa Clarita Valley Water Report is an annual report that provides current information about the requirements and water supplies of the Santa Clarita Valley.
