Ah, gotcha.
As a California resident, I can tell you off top that I don't really know what the fuck I'm talking about, beyond the most basic info and that you seem to know more about the shit than me...so keep that in mind.
But AS A RESIDENT, it seems to me that those cost to actually get those facilities built and up and running in any meaningful numbers that would make a difference, it would be wildly expensive. And it seems like almost every year, there is already a budget shortfall and some years, some level of government shutdown here because of it. The thought of trying foot the bill for the water system or whatever on TOP of that is prolly too much. Taxes are already too night here and a tax increase to pay for it would never pass a vote. The other option is to cut a huge number of program and services that may California...California.
That's my $00.02.
Go...
