“Even with newer systems that offer closed loop, the water needs to be replaced from evaporation and that's where the impact is to our local water sources.”
You are right, and we want to say so plainly.
Some data systems, especially the earlier ones ten or fifteen years ago, used over a million gallons of water per day. Newer designs use dramatically less. We said here on 20 September that we were checking a report that at least one recently built system uses none at all. We checked: Microsoft (December 2024) and Oracle (February 2026) both publish designs in which the cooling loop is filled once and then sealed, with no water consumed for cooling after that. The buildings still use water for the people in them, and none of this is a claim about this property, where there is no buyer and no design. The sources are in section 09. Checked 14 Oct 2026
“Closed loop” is a term that gets thrown around and it shouldn't be. A closed-loop system circulates its cooling water instead of consuming it, but it still loses water to evaporation and still needs replacement water. It is less. It is not zero. A number of facilities marketed as closed loop are in fact hybrid systems.
The useful response isn't to argue about the label — it's to demand a figure. Gallons per day, in writing, enforceable, on a meter someone local can read. A buyer unwilling to put that on paper has told you what you need to know.
