Virginia's Datacenters Guzzle Water Like There's No Tomorrow, Says FOI-based Report

Concerns over the environmental impact of datacenters in the US state of Virginia are being raised again amid claims their water consumption has stepped up by almost two-thirds since 2019, and AI could make it worse. From a report: Virginia is described as the datacenter capital of the world, particularly Northern Virginia where it is understood there are about 300 facilities. According to the Financial Times, water consumption by bit barns in some areas has increased markedly over the past five years by almost two-thirds. It cites data gathered by freedom of information requests to claim that more than 1.85 billion US gallons was used in 2023, up from 1.13 billion gallons in 2019. Those figures came from water authorities in Northern Virginia in Fairfax, Loudoun, Prince William, and Fauquier counties. Water is typically used in datacenters for cooling, and the FT points to anxiety over expected increases in demand for computing infrastructure due to AI, which is particularly power intensive during processing for training of large models. It reported that some existing facilities are in water-stressed regions, including parts of Virginia suffering from droughts.
