Data Center Operators Are Trying to Fix Their Water Use Problems

Data-center operators increasingly face water-use challenges as cooling needs collide with regional scarcity and regulatory scrutiny. Evaporative cooling, while energy-efficient in many cases, consumes substantial water, prompting debates about where and how it should be deployed. A recent Gallup survey highlighted broad public concern over data-center development tied to water resources. SpaceX even noted that water conditions could constrain data-center growth in its IPO amendment, underscoring the locality of the issue. In response, Google unveiled a package of water-related commitments, including replenishing more freshwater than it consumes, scaling up reclaimed and recycled water, and disclosing annual water usage. The company also emphasized a data-driven framework to tailor cooling approaches to local watersheds, based on four years of hydrologic assessments. Other major players—Microsoft, OpenAI, and Oracle—have signaled a move away from evaporative cooling in certain regions. The broader context remains nuanced: evaporative cooling can free grid capacity in some areas but requires substantial water, and projections from Lawrence Berkeley National Laboratory suggest data centers could consume tens of billions of gallons by 2030 if evaporative cooling is widely adopted. The evolving approach suggests a shift toward regionally adaptive cooling strategies that balance energy efficiency with water stewardship.
