Data Centers Clash With Water Crisis in West
18 Aug
Summary
- Two largest U.S. reservoirs, Lake Mead and Powell, at historic lows.
- Data centers cluster near Lake Mead, raising water usage concerns.
- States like New York and Texas are scrutinizing data center development.
The two largest reservoirs in the United States, Lake Mead and Lake Powell, have fallen to historic low levels. This crisis, driven by drought, overuse, and rising temperatures, impacts over 40 million people relying on the Colorado River system.
Amid this severe water scarcity, a debate has emerged regarding the suitability of the data center industry in water-stressed regions. A notable concentration of data centers exists near Lake Mead, especially around Las Vegas, Nevada, compared to Lake Powell. These facilities, while not drawing water directly from the lakes, contribute to the broader Colorado River Basin's water demand.
Modern data centers require substantial water for cooling and electricity. For instance, 23 Southern Nevada data centers were estimated to use over 716 million gallons in 2024. Critics argue that any new industrial water user adds pressure to a basin already exceeding its long-term supply.
Concerns extend to significant electricity demands, straining energy systems. Public opposition is growing, with a Gallup survey indicating widespread objections to AI data centers in communities. This has led some states to re-evaluate their approach to data center development.
New York enacted a statewide moratorium on new large data centers in July, pausing permits for study. Texas is auditing data center proposals seeking grid connection, requesting more details on their environmental impact. As federal officials develop new Colorado River management rules, the placement of future data centers will likely become a more prominent issue.
