Recycled Water Is the Texas Permit Edge. San Antonio Just Proved It.

San Antonio's data centers run on 75% recycled wastewater while a Georgia campus quietly pulled 29 million unmetered gallons before anyone noticed. The developers front-loading metering, recycled-water deals, and SB 6 load flexibility are clearing Texas permits while peers learn what unmetered means in a hearing room.

Today's Lead

A University of Texas study projects Texas data center water consumption rising from under 1% to as much as 9% of statewide use by 2040, with more than 400 facilities operating or under construction. The finding lands the same week San Antonio's CPS Energy showed how disciplined large-load policy can move the other direction: water consumption at just 0.1% of municipal supply, with 75% sourced from recycled wastewater.

The split tells the story. Texas can absorb hyperscale growth, but only where developers sequence water and power procurement before site selection.

Water

Transparency is now the permitting variable.

The UT Austin white paper from Mariam Arzumanyan and Vaibhav Bahadur names the gap plainly: no unified accounting for direct or indirect data center water use across Texas. Corpus Christi is supply-constrained, and the state estimates $174 billion in water infrastructure spending over 50 years to avoid crisis. Meanwhile in Fayette County, Georgia, QTS's Project Excalibur drew 29 million unmetered gallons over as long as 15 months before residents noticed pressure drops, and the county declined to fine its largest customer.

The contrast with San Antonio matters. CPS Energy's data centers run 75% on recycled wastewater, up from 48% in 2023. Developers who front-load metering, recycled-water agreements, and offset documentation will clear Texas permits faster than operators who treat water as an afterthought and discover it mid-review.

Power

Dispatchability is the deciding variable, and San Antonio is showing the math.

GridCARE analysts project that serving 1 GW of AI load on CPS Energy's system could generate roughly $123 million in annual revenue with near-zero incremental system cost, translating to a potential 4.4% rate cut, about $64 per residential customer per year. The mechanism is Senate Bill 6 load flexibility: facilities 75 MW and above can curtail or switch to backup generation during ERCOT peaks, unlocking idle transmission. CPS has set $75,000 to $150,000 interconnection study fees so data centers cover costs upfront. Large loads now hit 9% of CPS sales and are projected to reach 19% within five years.

The Africa gas buildout reinforces the underlying engineering reality: AI workloads need dispatchable generation, and gas turbines remain the only scalable source that meets the duty cycle. Texas's advantage is structural, but CPS's $1.3 billion transmission plan must keep pace with the queue. If interconnection slips, the revenue case for ratepayers slips with it, and the cost-allocation politics get uglier fast.

Politics

Other states are writing cost-shifting rules. Texas developers should read them now. Florida's SB 484, signed by Governor DeSantis, bars utilities from passing data center costs to residential ratepayers, gives local governments veto authority, and restricts water permits deemed dangerous to local resources. Maryland's Office of People's Counsel filed a FERC complaint over $2 billion in PJM transmission costs, roughly $345 per household annually, that customers say subsidize data centers elsewhere. NCSL tracked 4,207 state energy bills in 2025, with California, Nevada, and Oregon all enacting rate-impact scrutiny tied to large new loads.

Texas operates under ERCOT and the Public Utility Commission of Texas with different mechanics, but the political template is portable. Developers who structure interconnection agreements to absorb their own grid costs, and who can document it in plain language for local officials, will move through approval while peers fight the optics. The ones still hoping rate impacts sort themselves out are buying themselves a fight they don't need.
