【AI前沿】Data center guzzled 30 million gallons of water, and nobody noticed for months

“Absolutely draining us”Data center guzzled 30 million gallons of water, and nobody noticed for monthsCan AI save us from the AI industry’s endless thirst for water?

Even worse, the water grab came at a time when nearby drought-stricken residents were warned to restrict their personal water consumption, and some reported sudden decreases in water pressure.An investigation conducted by utility officials in Georgia’s Fayette County found that the Quality Technology Services (QTD) facility had two industrial-scale water hookups that weren’t being monitored. “One water connection had been installed without the utility’s knowledge, and the other was not linked to the company’s account and therefore wasn’t being billed,” Politico reported.QTS eventually paid about $150,000 for the water, but there were no consequences for exceeding peak limits established by the county during the data center planning process. Frustrating residents, the county declined to fine QTS. Fayette County’s water system director, Vanessa Tigert, told Politico that the decision was partly because the county blamed itself and didn’t want to offend QTS.“They’re our largest customer, and we have to be partners,” Tigert said. “It’s called customer service.”Notably, the main reason the water usage was overlooked is that the county is transitioning from outdated water meters to a smart, cloud-based system that is supposed to make it easier to track leaks and other unexpected drains on the county’s water system. Tigert also told Politico that the county failed to notice the water usage because it’s understaffed, explaining that the only worker available to inspect meters is “spread pretty thin.”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.AI industry can’t easily solve water crisisIncreased 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 areporton 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.”However, as hyperscale data centers from tech giants like Meta, Google, and Microsoft perhaps increasingly rely on power for cooling, the demand for water to cool down power plants will explode, experts suggest. And it doesn’t help that 40 percent of data centers and 29 percent of global chip fabs are bui
