When it comes to total water use, AI data centers are a drop in the bucket
Think globally, worry locally
While there’s no risk of big tech companies literally draining the oceans to power the data centers behind their LLMs, even moderately sized data centers can have an outsized effect on nearby water resources. A single Meta data center in Newton County, Georgia, for instance, now uses about 10 percent of the entire county’s water supply, according to a New York Times report from last year. And the Interstate Commission on the Potomac River Basin recently estimated that data centers account for 8 percent of total water consumption in the region, a rate that could climb to 29 percent by 2050 if the large concentration of data centers in northern Virginia continues apace.
That kind of concentrated water use can put severe strain on local infrastructure and water supplies, and has led to at least one situation where a data center siphoned millions of gallons from...
