Texas communities have a rare opportunity to secure fully funded support for critical water projects through the Texas Water Development Board’s (TWDB) Water Supply and Infrastructure Grants (WSIG) program. With $1.038 billion available and no match required, this one-time program offers significant funding to advance high-priority water supply improvements.
Program Overview
WSIG is designed to improve water system reliability and expand supply through projects that align with the Texas State Water Plan. Funding is highly competitive and prioritized for projects that are shovel-ready, well documented, and aligned with statewide priorities.
Funding is competitive and awarded based on project readiness and alignment with statewide priorities.
Grant caps are based on population served, ranging from $5 million to $40 million. Applicants serving populations over 150,000 may only request construction funding and must be ready to proceed at the time of application.
Eligible entities include cities, counties, districts, river authorities, and groundwater conservation districts. Applicants must also have up-to-date financial audits, water use surveys, water loss audits, and adopted water conservation plans in place.
Eligible Projects
WSIG supports water supply and infrastructure improvements, including:
- System upgrades, repairs, and replacements
- New or expanded water supply projects
- Water loss reduction and reuse efforts
- Projects resolving TCEQ water-related violations
Not eligible: wastewater, flood control, or drainage projects.
Allowable expenses include engineering and design, project management, grant administration, and construction costs.
Key Dates
- Application Open: Now
- Deadline: July 30, 2026
- Awards: To be announced via TWDB
What To Do Now
- Confirm your project aligns with water supply (not wastewater/flood)
- Ensure required documentation is current (audits, surveys, conservation plan)
- Assess project readiness (design, cost estimate, timeline)
- Engage early to position a competitive application before the July 30th deadline
