The water in question needs to be distilled and then purified heavily before going into a chilled water loop and mixed at a 50/50 ratio with glycol. These are closed loop systems, meaning that once the system is filled, it does not use more. Which means that once a system is filled, it doesn't use anymore resources, which means the aquifers refill.
Where does this protect the water thing come from?

It is suicidal to run untreated water thru a chiller to reach 40F. That is the temperature the water needs to be to flow into CRAH units to chill a data center. At above 48F, water is no longer able to work against the heat load in a data center. If a datacenter reaches 80F, the hard drives start failing as the temperature of the air is not able to offset the heat load.
How do you think cooling systems work in datacenters?
None of this is relevant, I don't even know what point you're trying to make.
Jewgle's datacenters use water, period. By their own admission:
> In 2024, we consumed a total of approximately 8.1 billion gallons (31 billion liters
or 31 million cubic meters) of water across our data centers (excluding those operated by third parties)
If that's the configuration, why would they not be set up for a geothermal heat pump configuration where they could dump the water in a different end of the aquifier?

these centers do use combined cycle power plants as a power source, which do use water. its not the equipment itself that requires the water, but the power plant. However there are systems now adays that minimize the use of water, that recycle the water and produce solid waste instead.
its not the "lack" of power generation, its that datacenters have their own private power sources, which do require water, but that water is not "consumed" as the general public thinks. Its cycled through multiple times. either way something is amiss with the general public sentiment vs reality. I dont know which is correct.

It’s to get rid of all the heat from the facility, not literally run river water over a GPU lol.

The cheap solution is a heat exchanger to normal water fed into an evaporative cooling tower.
Eventually any reservoir will become saturated and won't be able to store any more heat.
They're also very expensive. An evaporative cooling tower is cheap.

Stop spreading retardation.
