I don't quite understand how Phoenix, AZ, became the focus for chip fabs in the US, and even the recent CHIPS-backed TSMC investment. AZ does not have a lot of water, and the Colorado Basin treaties expire next year. There are interests from existing holders of water rights, the 7 US states, several Federal agencies (BLM, Army COE) and the international aspect with Mexico. I assume the negotiations are challenging and at some point, the Feds will step in, to direct water supply to chip fabs, rather than golf courses and almond groves.
