Desalination would provide a reliable, drought-proof and locally controlled safe water supply.

If implemented, the Doheny Ocean Desalination Project would provide high quality, locally controlled and drought-proof water supply while protecting the environment. Currently, South Coast Water District imports 85 to 100 percent of its drinking water, causing vulnerability during droughts, supply shortages and potentially during natural disasters.

Unlike traditional desalination facilities, the Doheny facility would use advanced slant wells that protect marine life by drawing water from beneath the ocean floor. Environmentalists and state regulators prefer this technology. Built into the system being considered by the District is also an energy recovery process, resulting in 45 to 55 percent less energy usage than systems without that feature.
