OCWD explores ocean desalination

OCWD has a responsibility to protect and secure Orange County's water

As part of OCWD's commitment to providing a reliable and sustainable water supply to Orange County, it is exploring ocean desalination as a way to increase local water supplies. This new source of clean water would reduce the region’s dependence on imported water sources from Northern California and the Colorado River that are vulnerable to drought, natural disasters, environmental concerns, and regulatory restrictions.

As currently envisioned, an ocean desalination facility would be built and operated by Poseidon Water in the City of Huntington Beach. OCWD would be responsible for determining the best way to distribute the water. The proposed facility would have the capacity to produce 50 million gallons of water per day, or 56,000 acre-feet of water per year, which is enough water for more than 400,000 people. OCWD is currently considering whether the purchase of this new source, if approved, makes sense for the 19 cities and agencies it serves.

Information including meeting agendas, reports, studies, press releases, and other related data will be updated regularly on this website. You may also view a chronology of OCWD's exploration of ocean desalination.
