Small Bottle, Big Pipe: Quantifying and Addressing the Impact of Data Centers on Public Water Systems
🤖 AI Summary
This study addresses the growing pressure that data centers’ cooling water demands—particularly during summer peak periods—exert on local public water supplies in the United States, potentially exceeding community water capacity. It presents the first systematic quantification of how data center water withdrawals affect peak loads on municipal water systems, integrating water use intensity (WUI) modeling, scenario analysis, and geospatial data. Projections indicate that by 2030, daily water demand from new data centers could range from 2.27 to 14.51 billion gallons—valued at $10–58 billion—with the high-growth scenario exceeding half of New York City’s daily water supply. The work proposes a “water capacity neutrality” concept and a water–energy co-planning framework to mitigate localized water stress and foster collaborative strategies between corporations and communities.

📝 Abstract
Water is a critical resource for data centers and an efficient means of cooling. However, meeting the growing water demand of data centers requires substantial peak water withdrawals, which many communities in the United States cannot supply, especially during the hottest days of the year. This largely overlooked water capacity constraint is emerging as a bottleneck for data centers and can force operators to rely on less efficient dry cooling, further stressing the power grid during summer peaks. In this paper, we focus on the direct water withdrawal of U.S. data centers for cooling and examine their impacts on public water systems. Our analysis indicates that, if the 2024 water use intensity persists, U.S. data centers could collectively require 697-1,451 million gallons per day (MGD) of new water capacity through 2030, comparable to New York City's average daily supply of roughly 1,000 MGD. Under an optimistic scenario with a compound annual water use intensity reduction by 10%, the water capacity demand decreases to 227-604 MGD, although high-growth IT loads could still require enough capacity to hypothetically supply about half of New York City for most of the year. The total valuation of the new water capacity is on the order of \$10 billion, reaching up to \$58 billion in the high-growth case. These impacts are highly concentrated on communities hosting data centers. Finally, we provide recommendations to address the growing water capacity demand of U.S. data centers, including reporting peak water use, developing corporate-community partnerships, adopting a Water Capacity Neutral approach (colloquially "Pipe Neutral") to allow host communities to retain limited water capacity resources, and implementing coordinated water-power planning to responsibly leverage water for peak power reduction and opportunistically utilize surplus power to mitigate impacts on public water systems.
