Observed
Water withdrawal and water consumption are different measures.
Withdrawal is water removed from a source for use; consumption is the portion not immediately returned to the local water environment.

Why does AI use water?
Computers turn electricity into useful calculation—and heat. Some facilities move that heat into the air; others use water evaporation; many combine approaches. Water can also be used indirectly by the power plants supplying electricity.

The answer changes when these conditions change.

Circulating is not consuming.
Withdrawal is water taken from a source. Consumption is the portion not immediately returned. A closed loop can still need makeup water or a separate heat-rejection system.

Estimated
A data center's water impact depends heavily on cooling design, electricity supply, climate, season, and the condition of the local watershed or aquifer.
The same annual volume can pose very different risks in different places and at different times of year.
Independent estimate
Estimated direct U.S. data-center water consumption rose from about 21.2 billion liters in 2014 to 66 billion liters in 2023 and is projected at roughly 140–280 billion liters annually in 2028.

Peer-reviewed study
In modeled scenarios, advanced cooling reduced greenhouse-gas emissions about 15%–21%, energy demand 15%–20%, and blue-water consumption 31%–52%.
