Well, the California Coastal Commission put the kibosh a few years ago on a decades-long desalination project: https://calmatters.org/environment/2022/05/california-desali...

I haven't heard of any new desalination projects making headway since. The cost-benefit analysis may favor it, but I'm not sure the politics do. Of course, those politics will probably change in 10-15 years in our next big drought cycle, and then we'll really wish we'd gone forward with more desalination.
