It was on a sailboat I used to own. It used a reverse osmosis system that required a lot of elbow grease and frequent filter changes. Still, it converted salty seawater into potable water. It was a lot of trouble, though.

If you get a desalinator. be sure its electric!

Here's a good list of such projects in California:

It sounds expensive, possibly more than the town is worth... not my personal opinion, but how big money people see things.

From my perspective getting rid of the toxic brine is the difficult part. There are no good solutions; at best there are acceptable ones.

I'm not an expert, it's just stuff I think about. Years ago, I used to be a regular at water board meetings. Here in California arguments about water can last decades.

This is a video about the Inland Empire Brine Line in Southern California that serves the deslalting plants and industries that produce salty wastewater.
