Good for them. No groundwater for data centers! Data centers should be run closed loop, if they can't, they shouldn't exist. AZ should also make them generate at least 70% of their power onsite.

It's worst. They use tap water.

I think the most cursed aspect in all of this is the fact that regions where evaporative coolers work best tend to have the scarcest water resources. Evaporative cooling is unreasonably effective when water is happy to evaporate. You can cut the power consumption of a datacenter by 70-80% in these regions if you are willing to sacrifice water.

I think in this case, solar energy is the best way to run the cooling systems, even if it requires an absurd amount of power to exercise compressors, etc. in order to improve heat concentration and rejection efficiency. As long as it's all green and theres a disaster recovery plan, who cares?

If you're doing large scale evap cooling in the Sonoran you're just removing water from an already stressed water table. I'd say put them somewhere cold and do district heating during the winter.

> Update: Brendan Gallagher, Beale's SVP of development, said in a statement: “We are disappointed in the decision not to pursue this opportunity for Tucson. [...] We see it as a missed opportunity for the city, as this project potentially represents tens of millions of dollars in tax revenue, hundreds of millions of dollars in infrastructure to serve the community, and thousands of high-paying local and union jobs.”

and I'm "potentially" the next president of the U.S.

What should water be used for then? They do large-scale agriculture in the same area, which uses several orders of magnitude more water while generating substantially less value.

This particular data center was going to build a wastewater pipeline to cool their facility with currently-squandered wastewater.

Please apply this rule to Tucson's 40 golf courses.

Food that people and livestock eat is less valuable than data centers used to chase the "AGI any day now" pipe dream? You're kidding right?
