The San Diego Regional Water Quality Control Board last week unanimously voted to begin work on a $300 million desalination facility to help meet the water needs of the region.
The reverse-osmosis desalination facility will be built by the Connecticut-based Poseidon Resources, and the company expects the facility to be online by the beginning of 2012. When it is fully operational, the plant will be able to produce 50 million gallons of drinking water every day, or about 10 percent of the region's water needs.
Poseidon is building the facility in Carlsbad, just north of San Diego, and it is just the first of many such facilities in the works in California. The state is in the third year of a drought, and faces pressures on water supplies from a growing population and agricultural water needs.
