Austin Joins Cities Limiting AI Data Centers Over Water Concerns
Austin moves to restrict new data centers
Austin, Texas, became the latest U.S. city to consider limits on AI data center development. On Thursday, the City Council voted unanimously to begin drafting rules that could restrict or exclude new facilities.
The move comes as communities across the country challenge the growing water and electricity demands of AI infrastructure. Austin officials will now draft changes to the Land Development Code to define data centers and set safeguards. The first phase of the ordinance is expected to be considered in December.
Water use by power plants is massive
A study by the nonprofit Ceres highlighted the scale of water consumption linked to data centers. Power plants serving data centers in seven states—Virginia, Texas, California, Illinois, Georgia, Ohio, and Arizona—withdraw about 3.4 trillion gallons of freshwater annually.
These seven states host roughly half of the nation’s data centers. The reported water usage equals 10.4 million acre-feet. For context, that amount exceeds California’s average annual urban water demand of 8 million acre-feet. It is also about 12 times the combined annual water use of Los Angeles, Phoenix, and Washington, D.C.
The study counts water drawn from rivers, reservoirs, and other sources to generate electricity. While some water is returned to the source, significant amounts are consumed through evaporation or other processes and are not immediately available for reuse.
Key numbers from the report
- At least 75 proposed data center projects worth about $130 billion faced local opposition in early 2026.
- 66% of the water-using power plants in the studied states were exposed to medium to high water stress.
- Cities in Texas, North Carolina, Kentucky, and New Jersey have also pursued bans or moratoriums on data centers.
Advocates criticize state inaction
Kaiba White, an Austin-based climate policy specialist for the consumer advocacy group Public Citizen, said the local vote contrasted with what it described as inadequate action from Texas state leaders.
White stated that while Gov. Greg Abbott has offered only performative and mostly voluntary measures, local leaders are acting to protect communities from the impacts of large-scale data centers.
Why this matters
The rise of AI has increased demand for energy and water, putting strain on local resources. As cities like Austin take steps to regulate these facilities, the debate highlights the tension between technological growth and environmental sustainability.
What happens next
Austin is currently drafting its Land Development Code changes. Council members are expected to review the first phase of the new ordinance in December.
