Danish pump manufacturer Grundfos is drawing attention to a previously underestimated effect of AI expansion: data centers require massive amounts of water for cooling. This endangers municipal water supply and sustainability goals.
Grundfos is calling for concrete regulatory consequences – a clear signal from a company that itself profits from water management solutions. The pressure is mounting: major tech companies are building data centers at record pace. The water demand for their operation is already competing with agriculture and households for scarce resources.
For building technology professionals, this means: cooling systems for data centers are becoming a regulatory risk. Efficiency standards, water cycles, and alternative cooling concepts are moving onto the checklist. Anyone relying on conventional large-scale coolers today could face restrictions tomorrow. Planners and operators need to adapt their infrastructure roadmaps.
