Texas Regulators Launch First-Ever Survey of Data Center Water Consumption
The PUCT study could reshape how the state plans water infrastructure as AI-driven facilities proliferate across Texas.
The Public Utility Commission of Texas has launched a first-of-its-kind survey requiring data centers and virtual currency mining operations to report their water usage, marking a significant step in the state’s effort to understand and manage the growing strain that large-scale computing facilities place on Texas water supplies. The survey, authorized through a budget rider in the state’s 2026–2027 appropriations bill and championed by State Representative Armando Walle, will collect data on direct cooling water use, cooling technology, and indirect water consumption through power generation. Facilities will have six weeks to respond, with findings compiled into a report by year-end to inform statewide water planning.
The survey arrives at a critical juncture for Texas water management. Existing data centers in the state consume an estimated 25 billion gallons of water annually through both direct use — primarily cooling — and indirect consumption driven by the power plants that supply their electricity. According to the Houston Advanced Research Center, that figure could rise to between 29 billion and 161 billion gallons per year by 2030, depending on the pace of construction and the cooling technologies adopted. Texas is already confronting a broader water supply crisis. The state’s latest water development plan estimates that shoring up water supply for the future could cost as much as $154 billion, nearly double the investment the Texas Water Development Board called for in its 2022 plan. More than 70 percent of voters approved Proposition 4 in November 2025, creating a constitutional amendment to dedicate up to $1 billion in annual sales tax revenue to the Texas Water Fund from 2027 to 2047 — potentially the largest water investment in state history. Against this backdrop, the rapid expansion of data centers introduces a new and largely unquantified variable into an already constrained system.
The survey’s results will be shared with both the Texas Water Development Board and the Texas Commission on Environmental Quality, positioning the data to directly influence regulatory frameworks, infrastructure planning, and permitting decisions. Representative Walle described the survey as a “softer approach” — gathering comprehensive data before pursuing legislation — but industry observers note that the findings could lay the groundwork for future regulatory requirements or water allocation standards for large industrial users. The implications extend beyond data centers themselves. Texas is simultaneously managing the Corpus Christi water crisis, where reservoir levels have fallen to historic lows and Governor Abbott has issued emergency orders. Communities across the state are implementing rate increases to fund aging infrastructure, with cities like El Paso approving 12 percent rate hikes and smaller municipalities like Jarrell adjusting rates effective April 2026. The intersection of surging industrial water demand from data centers with existing municipal and agricultural needs creates a complex planning challenge that the PUCT survey aims to quantify for the first time. Industry analysts note that data center operators choosing between air-cooled and water-cooled systems face significant trade-offs: water cooling is more energy-efficient but consumes substantial local water resources, while air cooling reduces water dependency but increases electricity demand on the ERCOT grid.
The convergence of data center growth and water infrastructure investment is expected to generate sustained demand for specialized talent across multiple disciplines. Water resource engineers, hydrologists, and environmental compliance specialists will be essential as regulators translate survey data into planning frameworks and potential new standards. Utilities facing both aging infrastructure and new large-scale industrial customers may increase recruitment of operations managers, distribution system specialists, and capital project directors capable of overseeing multibillion-dollar improvement programs. The data center sector’s water management needs are also creating a niche for professionals who bridge technology and water engineering — roles that combine expertise in cooling system design, water treatment, and regulatory compliance. As municipalities pursue rate adjustments and infrastructure upgrades simultaneously, demand for utility finance professionals, rate analysts, and public affairs specialists with experience navigating complex stakeholder environments may also rise. The Texas Water Development Board has already signaled this workforce pressure, offering $5,000 recruitment bonuses for licensed engineering candidates and actively partnering with educational institutions to build pathways into water sector careers.
Industry observers will be watching several developments in the coming months. The PUCT survey results, expected by late 2026, will provide the first comprehensive dataset on data center water consumption in Texas, and the findings will likely shape legislative proposals in the 2027 session. Concurrently, TCEQ is expected to propose rules in April 2026 regarding the land application of treated produced water from oil and gas operations — a regulatory development that could open new water supply options for industrial users. The trajectory of data center construction in Texas, driven largely by artificial intelligence workloads, shows no signs of slowing. How the state manages the intersection of technology growth and water scarcity will serve as a bellwether for other fast-growing states facing similar pressures. The PUCT survey represents a pragmatic first step — but the policy choices that follow will determine whether Texas can sustain both its technology ambitions and its water security.
