Texas estimates $174B water need

The Texas Water Development Board’s draft 2027 State Water Plan puts a hard number on the state’s water gap: $174 billion over the next 50 years. The draft, approved for public comment on April 16, says Texas will need thousands of projects to keep communities supplied through future droughts. The estimate is more than double the roughly $80 billion projected four years ago, according to Texas Tribune coverage of the plan. At the same time, a new University of Texas at Austin white paper says data centers could account for 3% to 9% of Texas water use by 2040, up from less than 1% today. ### Where does the $174 billion figure come from? The Texas Water Development Board said the draft 2027 State Water Plan was built from 16 regional water plans and identifies “thousands of actionable strategies and projects” with projected costs and sponsors. The board said the plan is meant to support 2026 commitments from the State Water Implementation Fund for Texas, or SWIFT, before a fuller Phase II amendment is adopted by January 5, 2027. (twdb.texas.gov) April 16 is the key date in the current process. The board approved posting the draft that day and said the plan represents the sixth statewide plan produced through Texas’ regional water planning system. Public comments are due by 5 p.m. on May 29, and the board has scheduled a public hearing for 1 p.m. on May 27 in Austin and online.

The University of Texas at Austin said on May 6 that rapid data-center growth could materially change Texas water demand because the estimate includes both water used directly for cooling and water used to generate electricity for those facilities. The university said the projection comes from a white paper by the Bureau of Economic Geology and COMPASS focused on how the industry’s expansion intersects with state water planning. (twdb.texas.gov) Texas already has a large and growing data-center footprint. ABC13, citing the UT Austin and COMPASS paper, reported that Texas had 484 data centers operating, under construction or planned as of September 2025. Houston Public Media reported the same UT research said the industry could reach as much as 9% of statewide water use by 2040 if current growth continues.

Daniel Michno wrote in Idaho Capital Sun on May 18 that Idaho is inviting new AI data centers into a state already dealing with drought stress and water competition. The commentary said facilities such as Meta’s planned Kuna site could lock in long-term industrial demand before state rules catch up. (abc13.com) The comparison is not that Texas and Idaho have identical water systems. It is that both are confronting the same basic siting problem: large compute campuses need land, power, permits and water at the same time. UT Austin researchers said Texas needs better transparency and coordination around data-center water use, while Michno argued Idaho needs state-level protections before more facilities are built.

Their white paper calls for integrated planning across water, energy and infrastructure as Texas absorbs more AI and cloud-related development. That makes water availability part of site viability, alongside grid access and local permitting. (news.utexas.edu) The resource question also feeds an industry argument for shifting more work to efficient devices rather than concentrating all inference in large centralized facilities. That framing appears in recent coverage and commentary around edge AI and efficient silicon, though the Texas water plan itself is a water-infrastructure document, not an AI policy paper.

Austin Building in Austin and via Teams, with written comments accepted through May 29. The board said a Phase II amendment with additional analysis is expected before the statutory deadline of January 5, 2027. (twdb.texas.gov)
