Amazon’s Texas AI campus clears a contested water hurdle.
A groundwater district approved limited well use for Amazon’s nearly 3,000-acre Wharton County campus, advancing construction while leaving cooling-water permits and a potential 780-megawatt load unresolved.
The Coastal Bend Groundwater Conservation District approved permits allowing Amazon to draw up to 78.2 million gallons from three wells over two and a half years for restrooms, construction crews and fire protection at its planned Wharton County data-center campus. Separate permits issued in May cover another 16.9 million gallons from two wells through February 2029.
The approvals do not cover the surface water expected to cool as many as ten data-center buildings across more than 1.9 million square feet, and those applications have not been filed. Site plans indicate 13 buildings in total; depending on final operating conditions, demand could reach roughly 780 megawatts, though Amazon has not confirmed a campus total while ERCOT reviews the project.

What changed
Amazon’s Wharton County plan and local opposition were already known. What changed is a specific regulatory approval for site-support water, which moves the project forward while making clear that cooling water and grid interconnection remain separate, larger gates.
02
Why it matters
AI infrastructure is increasingly scheduled by water, power and permitting rather than server availability. The Wharton decision separates the utilities needed to build a campus from those needed to operate it: Amazon can advance construction support, but still lacks a disclosed cooling-water permit and a confirmed power plan. That distinction matters to investors, utilities and local officials because partial approvals can create sunk costs before the largest system constraints are resolved. It also provides a more realistic template for evaluating AI campuses—permit by permit, load by load—instead of treating a headline investment as an operational commitment.
03
What to watch
Watch for surface-water applications, cooling design and expected consumption, ERCOT’s interconnection review, CenterPoint transmission plans, phased building schedules and enforceable reporting on groundwater levels and neighboring wells.
Why it was a runner-up
The permit decision exposes a consequential water-and-power constraint, but the campus is still prospective and the approved water is not the cooling supply; BMW has an operating production system today.
Impact: 86/100 · Confidence: 92/100
The Houston Chronicle reviewed the permit documents and reports the approved volumes, purposes, site plan and unresolved cooling and power requirements. The district record is authoritative, but Amazon has not confirmed the 780-megawatt estimate or final operating design.
