America’s AI Boom Is Creating an Unexpected Water Problem for Farmers
The U.S. data center boom tied to artificial intelligence is pushing utilities, cities, and tech companies to lock in more water for cooling systems and power generation. In farm-heavy states including Arizona and Texas, that growth is colliding with long-running worries about irrigation supplies, groundwater pumping, and drought.
Data centers are growing fast and water use is part of the buildout
Microsoft said in its 2024 environmental sustainability report that its global water consumption rose 34% from 2021 to 2022, reaching nearly 1.7 billion gallons, as it expanded cloud and AI infrastructure. Google said in its 2024 environmental report that its data centers consumed about 6.1 billion gallons of water in 2023, up from 5.6 billion gallons in 2022. Those totals are global, but they show the scale of water tied to the AI buildout.
In Mesa, Arizona, Google has developed a major data center campus, and the company said in its 2024 water stewardship material that it uses air cooling where possible and replenishment projects in water-stressed basins. In Texas, Microsoft and Oracle are among the companies linked to large data center growth around San Antonio and other power-rich regions, according to company statements and local economic development records. Exact water demand varies by design, weather, and power source, and companies do not publish every site-level figure.
Arizona and Texas are where the farm tensions are easiest to see
Arizona has become a flashpoint because the state announced in June 2023 that parts of the Phoenix area lacked enough groundwater to support some new housing construction under current rules. That same region includes new or expanding data center projects in Mesa, Goodyear, and other metro Phoenix cities, according to city records and company announcements. Farmers in central Arizona have already been hit by Colorado River cuts and groundwater limits, with Pinal County agriculture losing access to some canal water after federal shortage declarations.
Texas faces a different mix of pressure. The state is less dependent on the Colorado River system than Arizona, but the Texas Water Development Board said in its 2024 planning documents that population growth, drought, and industrial demand are all increasing competition for water. The full list of AI-related facilities drawing from specific local water systems has not been publicly released statewide, so it is not yet possible to calculate one verified total for farms versus data centers.
The bigger issue is not just AI, but where new water demand lands
Researchers and water planners have said the problem is less about one industry in isolation and more about fast demand growth in dry places. A 2024 report from the nonprofit World Resources Institute said data centers are expanding in several regions already facing high water stress, including parts of the U.S. Southwest. The Electric Power Research Institute has also noted that cooling choices, recycled water use, and hourly weather conditions can sharply change a facility’s water footprint.
For residents and farmers, the practical takeaway is that local impacts will depend on city permits, utility contracts, aquifer conditions, and whether companies use potable, recycled, or reclaimed water. Some operators, including Google and Microsoft, have said they are investing in water replenishment and efficiency, but project-by-project details remain uneven in public records. That means communities in Arizona, Texas, and other farm regions will likely keep looking at local hearings and utility plans as AI construction moves forward.
