The Water Replenishment District (WRD) is the largest groundwater agency by population in the state of California, managing and protecting local groundwater resources for four million residents. WRD's service area covers a 420-square-mile region of southern Los Angeles County, the most populated county in the United States. The 43 cities in the service area, including a portion of the City of Los Angeles, and other unincorporated parts of LA County use about 220,000 acre-feet (72 billion gallons) of groundwater annually which accounts for nearly half of the region's water supply needs.

WRD ensures that a reliable supply of high-quality groundwater is available through replenishment with recycled water and stormwater capture. WRD is responsible for monitoring and testing groundwater throughout the region using effective management principles. In 2013 and 2014, WRD was appointed by the Court as the Watermaster Administrative Body for the Central and West Coast Basins. In this role, WRD is responsible for administering the terms of the legal judgments controlling pumping, water right sales and leases, storage, and carry-over conversions.

WRD owns three water treatment facilities: two advanced water treatment facilities and a groundwater desalter. Furthermore, WRD leads the robust Regional Groundwater Quality Monitoring Program, a Safe Drinking Water Program, and a Water Education Program.
