Researchers from the University of California have presented alarming calculations about the water consumption of data centers, indicating that they could soon require as much cooling water as the entire city of New York. The issue intensifies particularly on hot days, as a significant portion of the U.S. landmass lies in warmer latitudes, leading to much greater cooling needs compared to locations further north. During peak demand, individual data centers could use millions of liters of water per day, especially those employing evaporation-based cooling systems.

By 2030, the projected peak water demand for data centers could reach between 697 to 1,451 million gallons (approximately 2.6 to 5.5 billion liters) per day. This is an astounding figure when considering that Finland, a country that does not officially track total water consumption, has an average water usage that is significantly lower compared to these projected figures from U.S. data centers. Such a disparity underscores the potential crisis looming in the future, particularly regarding water resources in regions facing both rising temperatures and an increasing number of data centers.

The implications of these findings could be profound, particularly as more data centers are built in water-scarce areas, raising concerns about sustainable water management and the environmental impacts of cooling large-scale data operations. As the demand for digital services continues to grow, the dependency on water-intensive cooling methods may create a conflict over this precious resource, potentially leading to crises in urban water supplies, particularly in parts of the United States that are already experiencing drought conditions or water shortages.
