Party Crashers and Water Myths: What the Data Center Fight Gets Wrong

.

A Party, a Microphone, and a Slogan

On Saturday night in Washington, D.C., hundreds of people gathered at a bar for "Data After Dark," a party celebrating data centers. According to Fox News, more than 600 guests attended. Organizers included Casey Givens, CEO of Young Voices, along with Jonas Du and Ed Tarnowski.

During the toasts, several protesters took the stage. One woman directed obscene gestures at the crowd and shouted about water use. Security removed her, and the room answered with chants of "USA."

Givens said the party was meant to counter what he called hysteria in the debate, and to highlight tax revenue, local jobs and the race with China.

The Political Backdrop

The scene comes as President Donald Trump pushes for a rapid buildout of data centers. He argues that America must stay ahead of China in artificial intelligence, and that communities blocking these projects hand Beijing an advantage.

Data centers are the physical backbone of AI. They house thousands of powerful computers that train and run AI systems. That equipment produces enormous heat, and that heat has to be removed somehow. This is where the water question begins.

Where the Water Story Comes From

For years, many large data centers used evaporative cooling. Water absorbs heat and then evaporates from cooling towers, much like sweat cooling skin. That water is truly gone and must be replaced.

The numbers from these older designs can be striking. One of Google's largest U.S. sites, in Council Bluffs, Iowa, has drawn about 3.9 million gallons per day and consumed roughly 2.8 million of it, according to the company's own environmental reporting.

Those figures feed the headlines. But they describe one type of facility, not the whole industry.

The Car Radiator Comparison

Newer AI data centers work differently. The chips are cooled directly with liquid that circulates through sealed pipes. The heat is released to the outside air, and the liquid goes back to the servers. Nothing evaporates.

Your car works the same way. You fill the cooling system once and do not top it up every time you drive.

Microsoft says its new designs will circulate water between servers and chillers without needing a fresh supply once the system is filled during construction. The company expects water use per facility to fall to near zero, and says all sites designed since August 2024 will use this approach. Oracle describes its AI facilities the same way: after an initial fill, there is no evaporation and no continuous makeup water for cooling. Operator QTS says it has used closed-loop designs at every new site since 2019.

Ongoing water use at such sites is mostly ordinary office needs, such as restrooms and kitchens.

Putting the Numbers in Perspective

Nationwide, data centers are a small water user. Research backed by Lawrence Berkeley National Laboratory put their direct on-site consumption at about 17 billion gallons in 2023. Irrigation of U.S. golf courses, by comparison, applied roughly 530 billion gallons in 2024, according to industry survey data.

In Maricopa County, Arizona, one of the driest and fastest-growing regions, a policy think tank estimates data centers will use around 900 million gallons in 2025, versus about 29 billion for golf courses. That source is an advocacy group, so treat the figures as one side of the argument.

.

The Honest Caveats

A fair account also has to include the objections.

Researchers note that comparing data centers with golf courses can mislead. Golf courses rely mostly on non-drinking water, while some data centers draw treated municipal water. A recent academic study projects that by 2030 U.S. data centers could consume 60 to 110 billion gallons a year, roughly 4 to 7 percent of consumption in public water systems. That could strain individual towns, even if the national picture looks modest.

There is also a trade-off. Sealed cooling uses less water but can require more electricity, and power generation itself uses water. Growth is fast, and local planning matters.

.

What Comes Next

The debate is shifting from "do data centers waste water?" to "which cooling design does each project use, and where is it built?" Those are questions communities can ask, and operators can answer with data. Requiring closed-loop designs in dry regions would address the concern directly, without stopping the buildout.

The party crasher's slogan was loud, but the facts are more specific than the chant. The industry is moving away from the water-hungry model, and public debate should catch up with that.
