19 million liters a day: How AI data centers are draining entire cities dry

There's this one woman who legally gutted an energy company over poisoned drinking water long before Julia Roberts turned it into an Oscar. Erin Brockovich, the living conscience of small-town America, has found a new favorite monster: the server farms that Big Tech is currently scattering across the country in the shadows. On her registration form , residents note what's springing up in their backyards—and we're not talking about gas stations or warehouses, but air-conditioned concrete cathedrals that guzzle electricity and water like a small town and behave as if they don't even exist.

Over 5000 messages have poured in within just a few weeks, and the title of their appeal gets right to the heart of the matter: If data centers are so beneficial, why are they being built in secret? It's a question the industry is answering with the same enthusiasm a vampire might have for a sunbath.

The thirst that no one expresses
Let's start with water, because it's so easy to measure. A single large data center can up to 19 million liters The amount of drinking water that evaporates daily is equivalent to the daily consumption of a city with 10,000 to 50,000 inhabitants, except that the city at least takes showers and makes coffee, while the servers merely run hot. Around 80 percent of this water rises into the sky as steam and never returns. In Loudoun County, Virginia, the world capital of server farms, the drinking water consumption of the facilities has increased. by over 250 percent within four years and now consumes almost a tenth of the total water in the district.

And that's just the beginning of the cost. UNU estimates predict that AI will consume up to 2,3 trillion liters of water per year by 2030. Google alone reported using over 19 billion liters in a single year, almost a third of which was drawn from regions with medium to high water stress . So, the thirstiest machines in human history are being built primarily in areas where water is already scarce – and this is called location optimization. Anyone who has ever observed how a corporation in California treats the resources of its neighbors can guess where this is headed.

The plug on which half the network depends
When it comes to electricity, things get even more outrageous. According to Gartner, the global energy consumption of data centers is projected to reach a new high by 2026. by around 27 percent to climb to 132 gigawatts, and then to 290 gigawatts by 2030. The US Department of Energy expects that server farms will reach a total capacity of 132 gigawatts by 2028. twelve percent of American electricity. AI-driven consumption grew in 2025 alone, according to the International Energy Agency. about halfIn Dublin, the plants now consume almost 80 percent of local demand, in Frankfurt over 40 percent – ​​welcome to a world where the electricity grid is no longer primarily built for people, but for matrix multiplications.

The bill for this, of course, doesn't end up with the multi-billion-dollar corporations, but in the mailboxes of local residents. A group of US senators has launched an investigation because electricity costs are skyrocketing near the power plants, and American families are effectively subsidizing the energy bills of companies whose market capitalization is greater than the GDP of half continents. Several states are working on legislation to at least slow the worst of the drain on resources.

Avoid transparency like the devil avoids holy water.
The question remains: why does so little of this leak out? The answer is refreshingly simple: because it's intentional. An NBC investigation examined over 30 projects in 14 states and found that in the majority of cases... Confidentiality agreements and shell companies. Elected local politicians sign non-disclosure agreements with corporations whose names they are not allowed to reveal to their own constituents. The projects operate under cover names such as “Project Bigfoot”, “Project Loon” or “Project Deacon”, registered via phantoms with names like Balloonist LLC – Meta only appeared in one case after the local council had already given its approval.

This is a deliberate tactic. When Google was asked about its water consumption in The Dalles, Oregon, it simply declared the figures a trade secret and litigated for years until a court finally forced the data out in 2022. The Lincoln Institute puts it politely: Companies tend to be rather reticent about their resource consumption. In other words: They're about as willing to talk about their water consumption as a data company is about its data collection.

That a bureaucratic legend from the nineties is now kicking the tech giants in the shins with a simple crowdsourced map has a bitter elegance. The world's most advanced technology requires the secrecy of a drug cartel to even be built—and calls that innovation. That residents can only access their own drinking water supply by court order, while the computer operator next door drains their river dry, is considered normal business practice. That one woman, with an online form, is forcing more transparency than all of Silicon Valley's investor relations departments combined says it all about the state of an industry that sells us the future while secretly draining the present—drop by drop, kilowatt by kilowatt, in the name of an intelligence too cowardly to show its own electricity meter!
