“You purify and you desalt at the same time.”Ĭohen explained that inland salinity can be the result of agricultural runoff or simply just topography: As snowmelt, rainwater and other water sources evaporate, they leave behind salt, especially in valley areas without good drainage. “You use the same technology of desalination, which is basically reverse-osmosis membranes, and that takes out the salt but it also takes out the nitrates other contaminants that may be in the water as well, such as pesticides,” Cohen said. (An acre-foot is approximately 326,000 gallons.) The median cost of producing desalinated water is “in the neighborhood of $2,000 an acre-foot,” he said. The Metropolitan Water District of Southern California, a wholesaler for 26 regional agencies, sells treated water at roughly $1,200 per acre-foot, Mitchell said.

“That’s sort of the Achilles’ heel of desal - its operating cost is very high because of its energy requirement,” Mitchell said.īut the price gap between desalination and other supplies is shrinking - particularly because the cost of traditional sources has been rising due to tightening supplies, increased treatment requirements, high pumping costs and other factors, he said. Not only does it take significant capital investment, but desalination also requires an enormous amount of energy to push saltwater through filtering membranes at a very high velocity, said David Mitchell, a water economist with the group M.Cubed and an adjunct fellow with the Public Policy Institute of California. Beyond the environmental impacts, economics have also discouraged widespread use of desalination.
