New UT Austin study finds data centers could raise water use by 2040

A collaborative study by researchers at the University of Texas at Austin and Compass Datacenters projects a significant increase in water consumption by data centers across Texas. The white paper, released last September, identified 484 data centers operating, under construction, or planned within the state, with Houston noted as a major hub. Currently, data centers account for approximately 1% of Texas's total water usage. However, the study forecasts this figure could rise substantially, potentially reaching between 3% and 9% by the year 2040. Dr. Ning Lin, principal investigator for COMPASS and chief economist for the Bureau of Economic Geology at UT Austin, underscored the importance of integrating data center infrastructure expansion with water stress mapping. This proactive planning, according to Dr. Lin, is crucial for communities to prepare for the growing presence of these facilities. Adding another perspective, University of Houston professor and energy researcher Harish Krishnamoorthy warned of the broader impact. He speculated that increased water demand could lead to a rise in water prices for consumers. Krishnamoorthy highlighted the substantial water footprint of AI usage, citing an example where three hours of AI use could consume an effective gallon of water, illustrating the magnified impact across millions of users.
