Comment on For states on the coast with excess solar energy why don't they invest in water desalination and pump that water back upstream?

I suppose the question is, what does a bucket of water cost if it comes from the groundwater or the next mountains/sea and what does it cost if it comes from a multi-million desalination facility... I mean even if the energy is free (which it's not) the whole plant has to be built, staffed and maintained. And having an expensive factory sit around idle during the night and peak power and just operational from 10am to 3pm isn't economical and makes it even more expensive. And regular water is cheap. Even after being carried around by trucks in the worst case.
