We already have one nearly finished in San Diego. The problem is that is makes for very expensive water because it's a large scale industrial desal plant and the technology still hasn't changed in such a way as to not require lots of energy. That said, it's still at least going to provide a huge amount of water with just the one plant so there is that.
