Desalination for residential use has been competitively priced for some time. In San Diego CA the greens try to stop new desalination plants because they say that the waste brine pollutes the ocean. As it is, the permitting takes longer than the construction.
One proposed workaround is to build a desalination plant in Mexico at the head of the Gulf of California and pump the fresh water into the USA.
