Data Centers 101: How Much Water Do Data Centers Use?

Americans rely on digital infrastructure to power their daily lives. From communicating with loved ones to managing healthcare, business, education, streaming entertainment and creative expression, our modern economy relies on cloud computing and data centers to power online services. Behind every click, swipe and video call lies a physical reality: the need for data centers.

As the public demand for digital services grows, so too does the public scrutiny surrounding the physical plant required to run them – data centers. Critics frequently paint an inaccurate picture of data centers as reckless, resource-draining giants that strain public utilities and threaten community resources, particularly alleging exorbitant water consumption.

The reality is quite different. The technology sector’s water usage is better described as small, transparent, flexible and responsible as companies work to accommodate their water usage to the capacity of the local community. Moreover, the industry pays to cover the costs of building and upgrading water infrastructure as needed, rather than residents bearing the costs.

The Economic Engine in Our Backyard

When a large data center comes to town, communities gain about 2,000 construction trade jobs, billions of dollars in investment and millions more in local economic development. Once in operation, a data center supports hundreds more full-time careers for high school and trade school graduates as technicians, who earn annual salaries averaging over $100,000. These stable positions offer incredible upward mobility right at home, creating sustainable career paths that support families.

Further, data centers are exemplary corporate citizens and taxpayers. Data centers pay millions in property taxes, enabling tax relief for homeowners while also providing funding for local schools, infrastructure and services. Far from taking resources away from residents, they provide the financial foundation that can keep rural and suburban municipalities thriving.

Dispelling the Water Myth Using Flexible Cooling Techniques

The most pervasive misconception is that data centers require constant, massive volumes of fresh water to prevent overheating. In reality, the industry relies on sophisticated cooling systems that are designed to fit the climate and available power and water.

Depending on climate and geography, some facilities use dry cooling entirely – like the electrically powered air conditioning in our homes and businesses. Today’s newest data centers hosting AI chips frequently deploy closed-loop, direct-to-chip liquid cooling systems paired with dry coolers, where a fixed volume of liquid circulates through a sealed loop to absorb heat directly from processors — consuming no operational water whatsoever.

Responsible Stewardship Tailored to Local Realities

Context is everything. Older data centers that relied on water for cooling actually consume less water than a municipal golf course. Where water is abundant, evaporative cooling can reduce electricity consumption by 20% on the hottest days of the year, where that water is partly recycled and partly evaporated, just like an irrigated farm field or municipal golf course. 

Where water is scarce, data centers rely on air cooling and reserve water exclusively for basic human needs on-site, like bathrooms and sinks, consuming less water than local restaurants. This geographic adaptation ensures community water resources are protected as digital infrastructure expands.

Financing the Future Through Infrastructure Upgrades and Watershed Restoration

Perhaps the most overlooked element of data center development is how the tech industry pays to improve electrical and water systems in its host communities. Companies typically cover the costs to build and upgrade needed water infrastructure — not as vague promises, but through binding community development agreements that modernize regional utilities at no cost to local taxpayers or ratepayers. Leading companies go further, funding upgrades to local water systems and restoring more water than they consume — actively investing in watershed preservation and long-term water availability for the entire community.

Conclusion

Cloud computing is woven into most everything in our daily lives. Data centers host the cloud, powering the services Americans depend on while generating life-changing economic opportunities, high-paying jobs and local tax relief. Through adaptable engineering, closed-loop cooling and massive private infrastructure investments, we do not have to choose between technological progress and good resource management. Data centers are built to be responsible, sustainable neighbors that help build up and serve their communities.
