LADWP is working closely with the State Water Resources Control Board on draft regulations to govern direct potable reuse (DPR), which is the process of putting highly purified recycled wastewater directly into the drinking water system. The regulations, which are due to be finalized by April 2024, mark an important step toward securing a sustainable local water supply for Los Angeles. As stated in a recent Los Angeles Times editorial, LADWP has sought to ensure the regulations not only foster public health and safety but also provide the necessary flexibility to successfully implement a large-scale water reuse program such as LADWP's Operation NEXT. Currently in the planning phase, Operation NEXT would initially use highly purified recycled wastewater to replenish our groundwater basins. LADWP may later apply the new DPR regulations to develop additional drinking water supplies for the city. LADWP will continue to collaborate with the Water Board to finalize the regulations, and develop new water supply opportunities such as DPR projects.
