California is going through a drought. However, there is a lot of water, salt water, to the west. My understanding is that Santa Catalina Island, west of Southern California, has a desalination plant to generate drinkable water from the ocean. What is the status of creating a desalination plant for Southern California?

There is some prime real estate at San Onofre while the power plant is being decommissioned.

    So, why the downvote? Isn't the status of a desalination plant based on politics? May 10 at 19:51

    desalination is (currently) extremely energy intensive. most of socal's water goes to irrigation, not drinking. that's not a cost-effective way of growing crops.

    @dandavis that's an answer, not a comment.

    @ThomasMatthews Your question is unclear as to whether a So Cal desalination plant is planned / exists and is held up by some political process, or if you're just wondering if one might happen. The former is an on-topic question, the latter probably isn't. May 10 at 21:40

    I don't know why the downvote was given, but reasons may have included "does not show any research effort; it is unclear ..." Basic research would have revealed that CA has 12 Existing Seawater Desalination Facilities including one at Carlsbad, which is south of San Onofre. Adding such basic research and asking about possible plans for San Onofre to the question may help to get it re-opened.
