The Insatiable Thirst of Big Data Centers

Evaporative Cooling

To stay cool, server farms rely on evaporative cooling. That process works by spraying water into large cooling towers, where it evaporates and carries heat away into the atmosphere. Unlike closed-loop systems that recycle water, evaporative cooling consumes it permanently. Once that water vapor rises into the sky, it is gone. It cannot be reused. It cannot be returned to your tap.

How Much Water Are We Talking About?

Training GPT-3, the predecessor of today’s AI models, consumed about 700,000 liters of clean water in just a few weeks. That is enough to supply over 10,000 showers (2,800 gallons), or to meet the basic daily water needs of 3,000 people. And that was just one model, trained one time. Now multiply that by hundreds of data centers, thousands of AI training runs, and millions of users running live prompts 24 hours a day.

Where Does the Water Come From?

In most cases, the water comes directly from your community’s drinking supply. The same aquifers, rivers, and municipal systems that feed your home are being tapped, quietly and invisibly, to cool machines. In many jurisdictions, these companies are not required to disclose their usage. There is no public hearing. No vote. No warning.

Are There Better Ways to Cool Server Farms?

Yes. Air cooling. Heat pumps. Liquid closed-loop systems. Even advanced heat recapture technologies that recycle warmth into nearby buildings. All of these systems require little or no water. The technology exists. But most companies do not use it. Why? Because evaporative cooling is cheap, cheap for them, but not for you.

The Human Cost

While server farms suck up drinking water, families in the same communities are told to conserve. Lawns go brown. Drought surcharges rise. Agricultural wells go dry. In some areas, residents are placed on water rations while nearby data centers use millions of gallons a day. The companies profit. The public pays.

The Economics of Server Farms: Myths, Math, and Misdirection

We are told that any attempt to limit use of public drinking water by data center server farms will cripple artificial intelligence, shut down cloud-based services, eliminate jobs, stifle innovation, and wreck the economy. Those claims are false. They are part of an unconscionable campaign of misrepresentation and disinformation, delivered with all the public relations polish that billion-dollar companies can buy. They have been crafted to justify unregulated expansion and unrestricted access to our public water supplies.

Server Farms Are Not Major Job Creators

Despite their size, data center server farms create remarkably few permanent jobs. A typical hyperscale facility employs 30 to 50 full-time workers, mostly in building maintenance, site security, and IT operations. Even the largest installations rarely exceed 100 employees, fewer than a supermarket.

According to the U.S. Bureau of Labor Statistics and economic impact assessments from states like Iowa, Oregon, and Arizona, server farms contribute fewer than 2 jobs per $1 million invested in construction. By contrast, manufacturing produces more than 7 jobs per $1 million. Median salaries at data centers also trend below regional tech sector averages.

The thousands of construction workers needed to build each facility create a short-term boom that disappears the moment the servers power on. The long-term local benefit is minimal. A single data center’s water demand can permanently destabilize nearby economies.

Water Use Is Vast; Economic Return Is Vague

You who live in those communities receive nothing in return for your precious drinking water. Data centers often pay below-market rates for water; rates negotiated in secret. Unlike agriculture, tourism, or manufacturing, which create jobs and recirculate revenue, server farms generate profits that flow upward to investors and corporate management, not outward into the local economy.

While server farms suck up their drinking water, families in the same communities are told to conserve. Lawns go brown. Drought surcharges rise. Agricultural wells go dry. In some areas, residents are placed on water rations while nearby data centers use millions of gallons a day. The companies profit. The public pays.

Corporate Profits Do Not Equal Public Benefit

Meta, Google, Microsoft, and Amazon do not operate server farms as public infrastructure. They operate them as private profit engines. Their data centers power advertising, e-commerce, entertainment, cloud platforms, and commercial artificial intelligence. Together, these four companies generate over $810 billion in annual revenue:

• ​Meta: $134 billion in revenue, $39 billion in profit.
• ​Microsoft: $252 billion in revenue, $89 billion in profit.
• ​Alphabet (Google): $324 billion in revenue, $74 billion in profit.
• ​Amazon Web Services: $100 billion in revenue, $24 billion in profit.

That is more than the gross domestic product of Switzerland and all of it depends on your public water. None of those profits return to the communities whose aquifers and reservoirs they drain./p>

The Data Center Boom Is Only Beginning

The explosion of artificial intelligence, streaming, cloud storage, and social media means more server farms. Many more. The demand is growing exponentially.

As artificial intelligence use spreads, the need for computational infrastructure is accelerating. Companies are racing to build new data centers across the country. Without intervention, water consumption will skyrocket, along with electric use. Once these centers are built, they will not be shut down easily.

Why the Public Isn’t Paying Attention

Most people have no idea that their drinking water is being used to cool computers. The companies behind these centers rely on nondisclosure agreements and friendly utility deals to conceal their usage. They call it “industrial water” or “non-potable infrastructure,” even when it comes from the same public sources as your tap. The truth is rarely disclosed in public reports or environmental reviews.

A Simple, Non-Negotiable Demand

No server farm should be allowed to use your drinking water to cool their computers. Not now. Not ever. Every drop of drinking water diverted to cool a computer is a theft from future human use. This is not about progress versus nature. This is about survival versus business convenience. Use recycled water. Use air. Use technology. But do not steal our drinking water.

If They Won’t Stop, Then We Must Act

The companies have no incentive to stop using our drinking water to cool their servers. That means we must act. We must make potable water off-limits for server farms. We must require full transparency about water usage. We must demand that cities, counties, and states deny permits to projects that consume drinking water. If they will not stop voluntarily, then we must make them stop.

A Note to Policymakers

Access to clean water is not a luxury, nor a bargaining chip to attract data centers. Legislators must stop treating this as a technical issue. It is a human rights issue. No community should have to sacrifice its future water security to satisfy the cooling demands of corporate servers. Write laws. Set limits. Protect your constituents before the crisis becomes irreversible.

The Path Forward: Public Action, Policy, and Enforcement

Either the people control their local drinking water supply, or they do not. Drinking water is social property, and the people of the United States are sovereign in their own communities. The issues are political, legal, and moral. Resolve the issues by establishing public control over your own drinking water.

Take Action Now

You must take action to protect your drinking water right now. You have the right and the responsibility to act. You do not need to wait for Congress or your State Legislature. You do not need permission from a federal agency. If your community supplies potable water to a data center or server farm, demand a public accounting. Request disclosure. Ask your water utility. Show up to meetings. Make the companies answer questions. Demand that they stop stealing your drinking water. And if they will not, make them.
