    Many data centres use water-based systems to cool the plant with towers evaporating the heat, like a huge perspiration system, which means that the water is lost. It also has to be drinking quality because impurities can damage the servers.

        Could do what nuke plants do and have another heat exchanger between the clean water and the water that evaporates, then use less clean water for that loop. If that’s too expensive it just means they aren’t being charged enough for potable water.

        That would take a lot of energy for a facility that is very energy hungry already. It is cheaper to pull in cold water from the mains and flush hot water down the sewer.
