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.

Here's what matters
The answer changes when these conditions change.
- 01Withdrawal versus consumption
- 02Cooling technology
- 03Potable, reclaimed, or other water source
- 04Peak summer use—not only annual use
- 05Watershed or aquifer condition
- 06Indirect water used to generate electricity

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.
