Data center guzzled 30 million gallons of water and nobody noticed for months

Ultimately, the county dismissed QTS’s excess water usage as a “procedural mix-up,” Tigert said, retroactively charging QTS at a higher construction rate for the water but imposing no penalties for taking more water than the county expected. Asked for comment, QTS told Ars that it’s “false and inaccurate” to suggest the facility “used any water improperly.” “Once this billing issue was flagged, QTS paid all charges,” QTS said. “All water usage followed relevant and applicable regulations.” QTS also pointed to statements from county officials denying residents’ claims that the facility’s excess water usage had decreased water pressure across the county system. Residents complaining about water pressure relied on wells, the county has said, while QTS does not draw water from wells or groundwater. Moving forward, the county confirmed that QTS’s water hookups will now be accurately monitored. Additionally, QTS emphasized that after construction, the facility’s water needs will drastically drop. However, residents are likely still stinging after receiving county notices recommending they restrict their water consumption due to ongoing drought conditions in the area. And some have lost trust in both QTS and the county. James Clifton, an attorney and property rights advocate who first exposed the QTS controversy after submitting a public records request, told Politico that he’s upset that QTS will face no consequences simply because “most months” they’re the county’s “No. 1 customer.” “The first thing they do is lean on the individuals and the citizens to stop water consumption when we have QTS that’s just absolutely draining us,” Clifton said. Increased demand for water to fuel America’s AI ambitions comes just as crumbling water systems across the country require upgrades, and, unsurprisingly, many AI firms expect AI to help address water supply problems in the industry. In a report on Monday, The Information explained why the water-supply question is a problem for the entire AI industry to solve—not just data centers, which are already finding ways to reduce and reuse water. Citing research from a water technology company called Xylem, The Information reported that “the water toll of AI is far greater at semiconductor factories and the power plants electrifying chipmaking and computing than at the data centers themselves.” The Environmental Protection Agency announced in March a system to strengthen and innovative water systems across the US, with early efforts focusing particularly on rural areas where budgets might be most stretched. However, the water sector isn’t completely sure yet how using AI might impact the nation’s systems and is not rushing to implement tech companies’ solutions. According to a 2026 State of the Water Industry report from the international nonprofit American Water Works Association, “utilities are cautiously exploring new technologies like artificial intelligence, recognizing both their potential benefits and associated risks, especially in the area of cybersecurity.” Most organizations haven’t implemented comprehensive solutions yet and “are not expecting revolutionary changes in the immediate future, the report said. For residents in embattled areas like Fayette County, questions about water remain. Although QTS plans to use a closed-loop cooling system that does not consume water for cooling when the data center is online, construction, which is draining far more water, is expected to continue for up to five more years, Politico reported. Additionally concerning to residents, data centers relying on “electricity-hungry equipment” for cooling “often entails a trade-off,” Politico noted. Consumer Reports reached the same conclusion in March, reporting that “generating the electricity to keep data centers powered up requires additional millions of gallons of water, even more than the water used for cooling.” That’s why communities aren’t satisfied with data centers promising that construction-phase water consumption represents temporary peak usage. In drought-plagued Arizona, a nonprofit advocacy group called Ceres estimated that data centers around Phoenix “already use approximately 385 million gallons of water per year for direct cooling need,” Consumer Reports noted. Once all that region’s data centers come online, “that amount will skyrocket to 3.7 billion gallons per year,” Ceres forecasted. In a letter to Congress last month, more than 120 organizations advocating against rushed data center developments warned lawmakers that it’s not enough to focus legislation on addressing spiking electricity bills. “Water use is equally alarming,” among other harms, groups said. “In drought-prone regions,” groups explained, data centers consuming up to 5 million gallons a day strain “drinking water supplies, agriculture, and ecosystems.” Meanwhile, closed-loop systems “require the use of toxic chemicals that, if not properly disposed of, can eventually flow and pollute water ways.” To avoid disastrous consequences for the country’s water supply, groups recommended that Congress pass laws requiring comprehensive environmental reviews prior to construction. They also want Congress to commit to rejecting “any legislation that would fast-track permitting and development for hyperscale, artificial intelligence, and other conventional data centers” through the end of this legislative session. Some efforts to protect water resources have had limited success, as backlash over secretive deals allowing data center developments without public notice increases. In Utah, one hyperscale data center in Box Elder County withdrew an application to transfer 1,900 acre-feet of water from a ranch to their facility. About 4,000 residents paid about $15 each to file notices of opposition to block that request, the Salt Lake Tribune reported. But although that battle was won, residents expect the larger fight to be far from over. As the war against data centers rages on beyond Utah, the Salt Lake Tribune editorial board published an op-ed, warning that officials risk eroding trust the more they shrug off residents’ reasonable concerns about things like water supplies, electric bills, air quality, and quality of life. “Even if the data center isn’t as dreadful as feared—or if it never is actually built—the stench attached to the rushed and secret political process will take a very long time to dissipate,” the editorial board wrote. “If it ever does.”
