'Green' Desalination

Over the past five years, desalination has gained significant momentum in California. With more than 10 projects in various stages of environmental review, design, and construction, desalination is planned to provide 1,500 to 2,000 million liters per day (ml/d) of new fresh drinking water supplies for the state by 2015.
