90% of water use in California is agricultural, not urban. Not sure about Arizona but it’s probably at least close. The city water problem is smaller than you think. Cities don’t directly use much water. I do think we will be forced by climate change to relocate some agriculture. We probably won’t be growing water heavy crops in the Southwest in 50 years.
