To be fair, a train from and to nowhere is waaaaaaaaaaaay more important than water.
Because the politicians in CA are too stupid to live.
Desalinization may soon get much better. Low maintenance nanoscale filters have been developed that use just a quarter of the energy used by reverse osmosis.
Basically they are vast numbers of tubes only wide enough to pass single molecules of water, and the molecules smaller than water are either non-toxic or volatile.
The end result is water even purer than distilled, because even air gasses have been separated out.
Israel
Israel Desalination Enterprises’ Sorek Desalination Plant in Palmachim is to provide up to 26,000 m³ of potable water per hour (2.300 m³ p.a.). At full capacity, it will be the largest desalination plant of its kind in the world.[95]
The Hadera seawater reverse osmosis (SWRO) desalination plant in Israel is the largest of its kind in the world.[96][97] The project was developed as a build–operate–transfer by a consortium of two Israeli companies: Shikun and Binui, and IDE Technologies https://en.wikipedia.org/wiki/Desalination#Israel
