Not all “water use” is the same. Agriculture returns it to environment through drainage into acquifiers and rain cycle, though the rain can fall outside of community. Showers go through sewage system, and treatment recycles it. Fracking destroys water by polluting and sequestering it. Data centers cooling requirements do not need any treatment before returning water back to community’s clean water supply, afaiu, though certainly if treatment were needed, the data center should implement it.

We can/should be angry about datacenter electricity use if that makes electricity more scarce for the rest of us, and uses climate terrorist energy to do so. But water use should not be a problem.

Article suggests that “evaporative cooling” means an open cooling cycle that releases steam. AFAIU, computer/data center cooling uses closed loops.
