Document Description
The City is proposing to implement a new advance treated recycled water (ATRW) infrastructure system that would maximize recycled water production at the Hyperion Water Reclamation Plant (HWRP) and construct new treatment, conveyance, storage, and distribution infrastructure to augment local water supplies by up to approximately 217 million gallons per day, equivalent to a third of the city’s water supply. The proposed Program would establish an integrated water resource strategy that provides a new local water supply source to sustain the long-term reliability and utility of local groundwater basins and decreases the Los Angeles region’s dependence on imported water supplies. To do this, LADWP would increase recycled water treatment facilities, water conveyance pipelines, and groundwater recharge and extraction capacities within the Central, West Coast, and San Fernando Groundwater Basins. LASAN would install advanced treatment processes for the production of recycled water at HWRP. The Program would also enable future opportunities for direct potable reuse with ATRW supplies produced at the HWRP.
