The problem is that’s not what happened here. This data center is under construction. It’s not operational yet. So the construction used this water over a period of months for dust control and mixing concrete and so on and weren’t billed for it.
Also, the way data centers are supposed to use cooling is something called a closed loop. It’s similar to what you have in your vehicle. Or a liquid cooling setup in a computer. So the water isn’t supposed to go back into the cities water table or their treatment system.
The water from the construction will do that but it is no longer potable so it has to be retreated to be safe to drink etc.





In a closed loop cooling system for a water cooled PC you use distilled water to prevent things growing in it which would require the system to be purged and cleaned and refilled. Which would use more water. So for cooling a data center I’m sure it’s a similar deal.
They can probably use grey water for the construction (which is where the 29 million gallons of water were used in this instance), so I don’t know why they didn’t other than the sheer amount of water needed and whether or not grey water was available to be used.
