Imported Water

The Metropolitan Water District of Southern California (MWD) is responsible importing water from the Sacramento and San Joaquin Rivers through the State Water Project and from the Colorado River via the Colorado River Aqueduct. Imported water is a supplemental resource to groundwater.

Southern California receives about 30% of its water from the State Water Project and relies heavily on the Colorado River Aqueduct. For over 70 years, the aqueduct has been supplying the region with a major source of supplemental water.

As an MWD Member Agency, Central Basin delivers imported water from the State Water Project and the Colorado River Aqueduct to its service area.

Groundwater

In 1952, Central Basin was formed to provide the Southeast Los Angeles region with a supplemental source of water. During that time, the cities of this region relied heavily on groundwater. This source of water is located beneath the earth's surface and requires users to pump the water out. Central Basin's role today is to continue providing a supplemental source to groundwater.
