As data center development continues to expand—driven by demand for artificial intelligence, cloud computing and other digital infrastructure—the use and availability of water have emerged as a key consideration. As discussed in our prior article, the scale of water use associated with large data center operations is drawing increasing scrutiny as a primary policy concern for data centers. While factors such as the size of the facility, the design of its cooling system and local climate conditions will affect the water volumes necessary for operations, large data centers may require as much as five million gallons a day, comparable to the municipal demand of smaller cities. As a result, water sourcing and reuse are becoming central to both operators and local, state and federal government officials tasked with regulating and legislating on these issues.
