I don’t think this is actually as bad as people say.

It’s not that we won’t have drinking water. Municipal water use is tiny! And provided with enough incentives (higher costs) people will use less water. And this can be done in very reasonable ways by issuing water tiered rates.

Agricultural water use, is a whole different topic. However, until we can incentives better water management on our massive agricultural lands, it’s only going to get worse.
