This is just pure histrionics, you have no understanding whatsoever of the scale of data center water consumption, electricity consumption, new capacity coming online, etc.
It’s bad to pump non-renewable fossil aquifer water in Arizona for evaporative cooling, but using cooling towers in an area that gets 30” or more of precipitation per year is probably not going to hurt anything.
The issue isn't comparative usage to existing hookups, it's new cost burden on the local community where a data center is built. Which is why DC propogandists switched to the golf course measurement, it confuses the original concern, the cost to the community of new DC hookups to municipal water or the very limited amount (of expensive to the community) available hookups that were intended/funded by the community for other purposes.
