Ai does us a crap-ton of water. Most data centers use closed loop liquid cooling with heat exchangers to water cooling. (At least all the big ones like Google and Amazon do)

I’m curious what evidence you think you’ve seen to the contrary. from my side, I used to build data centers and my friends are still in the industry. As of a month ago I’ve had discussions with Google engineers who build data centers regarding their carful navigation of water rights, testing of waste water etc.

If these data centers are so water efficient, please explain the Dalles data center use > 25% of their water supply?

Parent says consume, you write use.

I’ve been unclear on this. What datacenter out there is using an open loop cooling system that does not return the water after cooling for other uses?

It seems extremely inefficient to have to filter river water over and over then to dump it into the ground so deep it doesn’t go back to getting into an aquifer.
