On edit, with regard to the amount of energy needed, that is a challenge that comes with a great reward. If we gear up our solar energy resources to desalinate water, we can develop solar energy and other sources of energy as well as fulfill our water needs.
We hear of the likelihood of rising ocean levels. That will change the ocean's ecology in any event. The amount of disturbance that desalinating water for California would cause will not seem so important compared to the problems that climate change cause.
Making recycled water drinkable and safe for bathing will cost an enormous amount of money.
And in the long run, the quality of water will decline.
