How Much Water Do Data Centers Use? Can New Tech Tackle The Problem?
Key Takeaways Water availability is becoming as important as power availability when deciding where AI data centers can be built and kept running long-term. A large share of data centers built since 2022 sit in regions already facing water stress, including parts of Texas and Arizona. Conventional cooling forces a tradeoff between water-hungry evaporative systems and power-hungry, density-limited air cooling. Waterless architectures remove that tradeoff by using closed-loop immersion cooling instead of evaporative water use. Understanding how water scarcity affects permitting, regulation, and siting risk can help infrastructure planners avoid costly surprises down the road. Every AI infrastructure conversation seems to circle back to power: how much of it a facility needs, where it comes from, and whether the grid can keep up. But now it is water use that is taking up the airtime. High-volume water usage for cooling is just as urgent a limit on where AI data centers can be built and h...
