Water way to go...

Okay, I think I have an answer to the brine disposal issue inherent to the desalinization option in handling the So-Cal water shortage.

In the first place, set the plants up as a State Public Utility, sell the water to the private company and rebate the profits back the tax payers, less expenses. Second, you can power the plants by setting up solar farms on the other side of the inland mountains, providing local jobs to the natives. Third, you pump the brine back out to sea using off-shore wind turbines, diluting it using seawater in increasing volume until you discharge it at the edge of the continental shelf.

I advise talking to the Dutch about engineering.
