The Project will construct the Doheny Ocean Desalination facility, which includes a subsurface slant well intake system (fully buried in sand at Doheny state beach), raw (sea) water conveyance to the desalination facility site, a seawater desalination plant (on District-owned property), brine disposal through an existing wastewater ocean outfall, solids handling facilities, and potable water storage and delivery to adjacent distribution infrastructure. The Project will provide up to 5,321 AFY of new potable water supply to implement the California Water Plan and meet Southern California's critical need for water supply reliability enhancement. The Project design includes photovoltaic solar panels onsite and potentially offsite renewable options. The Project's subsurface intake system provides an innovative use of new technology to reduce adverse environmental impacts from water withdrawal and serves as a seawater intrusion barrier to improve the Basin's groundwater quality and supply to protect public health. Over 10 years of environmental study, regulatory permit approvals, and stakeholder meetings with the general public, environmental groups, and regulatory agencies have been completed to date.
South Coast Water District
The objective is to construct an ocean desalination facility to produce up to 5,321 AFY of new potable water supply to increase local water reliability and decrease regional dependency on imported water diversions from the Colorado River Aqueduct and the State Water Project (Bay Delta). Innovative feedwater intake from subsurface slant wells and use of existing outfall for brine release will protect local groundwater, public health, and the environment.
