OK, it’s a given that water is a limited CA resource.
My memory is telling me where I’ve read that the sandbox regions of the Middle East is also water deprived. They cured the problem with massive water treatment units that make sea water usable. My memory also is telling me that this process was offered to CA, but it was rejected. Am I correct?
If I am then CA is using water as a political tool much the same way as with big oil, fracking, coal, spotted owls, global warming, big pharma, health care, gun rights, sugar, plastic straws, old fashioned light bulbs - the list is endless.
80% of the rainfall in CA is in the north and 80% of the usage is in the south.
No matter how they handle it, that’s gonna create tension.
“Am I correct?”
I’m unsure but nobody has to offer known, routine technology.
I think the issue has always been cost. Desalination requires substantial energy input.
Of course a combined nuke plant/desalination plant would be as efficient as anyone could hope for and it could provide drinking water to the southland. And other areas on the coast which need it.
