A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

Water used to cool data centers is either consumed, meaning it evaporates into the atmosphere via the data center’s cooling towers or discharged, as industrial wastewater, usually to a local wastewater treatment plant.

It can't just be dumped into a river, has to go to a sewer treatment plant.

edit: They do recirculate it, but it eventually needs to be replaced. And some facilities have treatment plants on site, so doesn't necessarily needed to go to a sewer treatment plant.
