Most chip plants recycle/reuse/reclaim almost all their water. Intel has always had that in the US, been doing that since the 90s in Arizona, and around 97% of water is fully reused.

Another aspect is it industry is built in the US and Arizona makes sense from environmental impacts (no earthquakes, hurricanes, winter etc) then the industry will make sure more water makes it to Arizona.

In a way having production in the desert there will lead to water innovation, like pipelines/geoengineering/solar stills/desalination/innovations on recycling more water and many other things.

Necessity drives innovation.
