Water Replenishment District of Southern California

The Water Replenishment District of Southern California is a public agency that manages groundwater supplies in Los Angeles County. Its primary role is to ensure a reliable supply of clean, safe groundwater for residents and businesses by replenishing aquifers that may become depleted due to overuse or drought. It achieves this through collecting, treating, and recharging imported and local water into underground reservoirs. This helps maintain local water levels, prevents land subsidence, and supports sustainable water management in the region.
