They used to call California ocean desalination a disaster. But water crisis brings new look
For decades, environmentalists have decried ocean desalination as an ecological disaster, while cost-savvy water managers have thumbed their noses at desal’s lofty price tag. But as the American Southwest barrels into a new era of extreme heat, drought and aridification, officials and conservationists are giving new consideration to the process of converting saltwater into drinking water, and the role it may play in California’s future. Although desalination requires significant energy, California’s current extended drought has revived interest in the technology. Experts are already experimenting with new concepts such as mobile desalination units and floating buoys, and at least four major plants will soon be operational along the state’s coastline.
