How Much Water do Google’s Data Centers Use?

This map locates Google’s GOOGL data centers that consume the most water in America. Data is sourced from Google’s 2024 Environment Report.

Why do data centers need water? It’s because computer servers generate significant heat that must be dissipated to maintain performance.

As a result, water is used in chiller plants, evaporative cooling systems, and humidification to manage temperature levels.

Ranked: Google’s Thirstiest Data Centers

Google’s data center in Council Bluffs, Iowa consumed nearly 1 billion gallons of water in 2023, by far the most by any single complex listed in their report.

All of that water was potable, i.e., safe for drinking.

The data center complexes in Mayes County, Oklahoma and Berkeley County, South Carolina are the next “thirstiest,” using 750–800 million gallons of water a year.

These top three locations are well-above their counterparts across the U.S., and the rest of the world in water usage.

 Fun fact: the U.S. has  of the world’s 12,000 data centers. Germany and the UK are distant runners-up.

Together all of Google’s data centers used nearly more than 6 billion gallons of water in 2023, the equivalent of 41 golf courses.
