Grey water like you talk about could be huge. Really big.

Desalination could be interesting but is pricey to scale.

What I want to know is how expensive or unfeasible it really is to just make a long ass pipeline from some other part of the US that gets stupid amounts of rainfall. We do it with oil - isn't water easier?

The amount of water we use is several orders of magnitude greater than oil. I believe I once saw a calculation that you would need like 10 96 inch pipes just to serve California households let alone agriculture.
