They could do that… it does cost twice as much to process the water and the water, energy costs being a large factor… and we do know that the power infrastructure of California is rock solid /sarcasm.
The restrictions on water usage doesn’t mean that they are going to cut someone off… they are simply going to pay more… which would happen under desalinization. This bill is a directive to water providers, not individuals, to plan water use more efficiently. And in fact, it is a response to some water agencies wanting more local control after finding that the drought restrictions were too inflexible and a one size fits all regulation that didn’t take regional differences into consideration.
But let us ignore all of that and point to the kooky Californians managing a scarce resource with input of local control as a bunch of moonbeam water hating hippies.
Except that it had broad support from business and environmental groups. So there is that.
