Data Centers Are Guzzling California’s Water. We Have No Idea How Much

Data center builders don’t tell the public how much water they use, according to a new report — and the industry is encroaching into water-stressed and vulnerable communities.

The report, by the think tank Next10 and researchers at Santa Clara University, finds that planned data centers — the ganglia of artificial intelligence — are spreading to regions reliant on overtapped groundwater and strained surface water, with potentially major effects in the Central and Imperial Valleys.
