Texas AG sends water-use compliance letters to DFW data centers

The Texas Attorney General’s office sent letters to 156 data center developments statewide, including ones in Dallas, Tarrant, Collin and Denton counties. The letters tell them to provide up-to-date and accurate information on their water use, according to an Oct. 15, 2026 release from the office. They are part of an investigation the office previously announced into data centers that have not answered a Texas Water Development Board (TWDB) water-use survey.

For DFW developers and site-selection teams, the letters are a demand for information, not a citation. No development is named publicly, no penalty has been announced, and the AG’s office has not released the letters’ full text. But the action puts a state regulator’s attention squarely on the same four-county corridor, Dallas, Tarrant, Collin and Denton, where our own tracking already shows four active TDLR filings totaling $1.168 billion. Operators that have not filed a TWDB water-use response now carry a second compliance channel to watch alongside their state registrations.

Why it matters

Water-use reporting for large industrial loads has become a live regulatory front in Texas this year, running alongside ERCOT’s large-load interconnection rules under SB 6. A letter is a lower-stakes instrument than a lawsuit, but the release ties it to an active investigation, and it shows which counties hold the developments the office is looking at. All four DFW counties named sit inside the corridor the Dallas market page already tracks for active data center construction, so the letters add a reporting-compliance layer on top of permitting activity our wire already covers.

The numbers

The release covers 156 letters sent to developments in 32 counties statewide, with Dallas, Tarrant, Collin and Denton among them alongside Harris, Travis, Bexar and others. Hood County, southwest of Fort Worth, is also on the list. The office has not broken out how many of the 156 letters went to DFW developments. The investigation centers on developments that have not responded to the TWDB water-use survey.

What’s next

The letters request water-use information, not a hearing date, and no lawsuit or penalty has been filed. No recipient has been named publicly, and the release gives no response deadline. Whether any DFW-area recipient faces further action depends on what its response shows, and on whether the office moves from investigation to a filed case.
