For Texas Water Supply and Infrastructure Projects
WSIG provides 100% grant funding — not loans — for eligible public water systems ready to plan, design, and build.
The Water Supply and Infrastructure Grants (WSIG) program is a one-time state funding initiative administered by the Texas Water Development Board. Created through House Bill 500 (HB 500), the program allocates $1.038 billion in direct grant funding for eligible water supply and infrastructure projects.
Unlike traditional TWDB programs, WSIG does not require repayment, making it a rare opportunity for Texas communities to advance critical projects without increasing long-term debt.
Funds must be awarded and contractually committed by August 31, 2027, or they will expire.
WSIG funding is limited to public entities and political subdivisions in the State of Texas.
Eligible applicants include:
Cities and municipalities
Counties
River authorities
Special law districts
Irrigation and water control districts
Groundwater conservation districts
Not eligible:
Water supply corporations (WSCs)
Investor-owned or private utilities
Eligibility is statutory and non-negotiable. Confirming eligibility early is a critical first step.

WSIG supports a broad range of water supply and infrastructure improvements, including:
Repair or replacement of aging water systems
Correcting system deficiencies (pressure, quality, water loss)
Expanding service to underserved or growing areas
Purchasing water rights or system capacity
Water reuse projects that increase supply
Efficiency and loss reduction initiatives
Ineligible projects include:
Wastewater treatment facilities
Flood control or drainage projects
Projects outside water supply or infrastructure scope
TWDB evaluates WSIG applications using a structured scoring framework that considers:
Median household income (AMHI) in the service area
Population served and system size
Prior receipt (or lack) of TWDB funding
Project readiness (engineering, permitting, easements)
Consistency with the 2027 State Water Plan
Projects that are “ready to proceed” consistently score higher.
While final awards are subject to TWDB prioritization, proposed funding ranges include:
Small systems (<10,000 population): up to ~$5 million
Mid-sized systems (10,001–150,000): up to ~$15 million
Larger systems: $25–40+ million based on need and readiness
Projects with completed planning, engineering, and environmental work are generally more competitive for higher award levels.
WSIG is a time-limited, one-time program, making early preparation essential.
Application window: Expected March–July 2026 (120 days)
Award announcements: Late 2026
Grant contracting & close-out: 2026–early 2027
Funds available for projects: August 2027
Communities that wait until the application window opens often face avoidable readiness gaps.
Holistic Utility Solutions provide end-to-end WSIG support, from early planning through post-award delivery.
Our services include:
1
Identifying WSIG-eligible projects aligned with funding thresholds and prioritization criteria.
2
Evaluating statutory eligibility, State Water Plan alignment, and project readiness.
3
Developing narratives, coordinating documentation, and supporting compliance requirements.
4
Supporting contracting, reporting, scheduling, and owner’s-agent services through construction.
Don’t miss your chance to secure grant funding before deadlines close.
WSIG isn’t a program that comes around every year, so getting started early really matters. The communities that take action now tend to put together clearer, stronger applications, avoid the last-minute scramble for engineering or documentation, and move faster once awards are announced. Starting early also puts you in a better position to compete for larger funding amounts. Waiting until the application window opens usually means fewer options and a tougher road to funding.
We are currently building a WSIG interest list for Texas communities seeking early guidance and application support.
