Recycled Water

LADWP has made water recycling a key strategy of the Urban Water Management Plan

As the City’s imported water supply becomes more critical, so does the need to expand our local, sustainable water resources, including water recycling. Water recycling offers a reliable, economically feasible and environmentally sensitive way to augment the city's water supplies. Recycling programs treat wastewater so that it can be used safely for irrigation and industrial purposes, groundwater replenishment, as a barrier against seawater intrusion and for other beneficial environmental uses.

LADWP has made water recycling a key strategy of the Urban Water Management Plan (UWMP). The UWMP is a blueprint for creating reliable sources of water for the future of Los Angeles. The goal is to increase the total amount of recycled water to 59,000 acre-feet per year by 2035.

Los Angeles has used recycled water since 1982 for irrigation. Recycled water keeps the landscape healthy in areas of Griffith Park, along with the Mount Sinai and Forest Lawn Memorial Parks. Currently, the LADWP is expanding its recycled water program to include both groundwater replenishment utilizing advanced treated purified recycled water to recharge groundwater supplies and a large purple pipe distribution system.
