San Diego plans to pump that salt right back into the Pacific Ocean which according to Nasa, will cause big problems, quickly :

It will also kill lots of marine life.
Unfortunately I don't see any other choice for California... |
So basically one plant will produce 8% of what California needs. Wonderful. Build ten plants, and our problem is solved.
Of course there are downsides, but again they build entire cities in the desert in the Middle East and they seem to have it figured it out.
