There is currently no public breakdown of U.S. data center water consumption by AI versus non-AI workloads. However, AI appears to account for a minority of total data center compute and electricity demand today, suggesting its share of water consumption is also likely to be a minority, though the exact proportion is unknown.

However I can give some examples of cloud services:

AWS / Amazon data centers used roughly 2.5 billion gallons globally in 2025

Google data centers used roughly 7.7 billion gallons globally in 2024

All U.S. data centers: about 17.4 billion gallons/year direct water consumption in 2023, projected to reach 38–73 billion gallons/year by 2028. That includes cloud, AI, enterprise, colocation, storage, etc.
