Texas has made more than $1 billion available to help communities address water supply and infrastructure challenges — and PFAS treatment qualifies. If your water system has detected PFAS above the EPA's maximum contaminant level, this funding may be your clearest path to compliance.
Texas House Bill 500, passed during the 89th Legislative Session, appropriated $1.038 billion from general revenue to the Texas Water Development Board (TWDB) for water supply and infrastructure projects. This is a one-time grant program — funds do not carry over and the application window is firm.
What the grant covers
- 100% grant coverage — no local match required
- Eligible for municipalities, cities, municipal utility districts, and governmental water entities
- PFAS treatment systems qualify as eligible water supply infrastructure
- Funds held in escrow through August 2027 — four-year construction window once awarded
- Application deadline: July 30, 2026
One critical requirement: you need an engineering firm
Applications must be filed by a licensed engineering firm on behalf of the municipality — not by the water system directly. This means the first step is not filling out a form. It is finding a qualified engineering partner who can file on your behalf.
Time is short. Engineering firms need time to assess your system, prepare documentation, and submit a complete application before July 30. If you have not already begun this process, now is the time to move.
Hexivon connects qualifying systems with engineering partners — at no charge
Hexivon is a Dallas-based water technology company that permanently eliminates PFAS from water — not just filters it. Unlike conventional treatment methods that concentrate PFAS into a secondary waste stream, Hexivon's proprietary process destroys PFAS at the molecular level. No spent carbon. No toxic concentrate. No problem moved elsewhere.
In a 2025 pilot in Cary, North Carolina, Hexivon took water contaminated at 40 parts per trillion and delivered a non-detectable result — continuously — at 150,000 gallons per day, with zero waste stream produced. Independent, EPA-certified labs verified the results.
Hexivon connects qualifying DFW water systems with engineering partners experienced in HB500 applications — at no charge. The company works alongside your engineering firm to ensure your PFAS treatment system is properly scoped, documented, and positioned for funding.
The compliance clock is running
The EPA's MCL for PFOA and PFOS — 4 parts per trillion — is now federal law, with compliance required by 2029. Across Dallas-Fort Worth, 29 public water systems have already recorded detections above that level. Communities that act now, while HB500 funding is available, can address compliance on the state's dime. Communities that wait will face those costs alone.
