Texas voters approved Proposition 4 in November 2025, a constitutional amendment that dedicates up to $1 billion per year in existing state sales tax revenue to the Texas Water Fund through 2047. The money goes toward pipeline construction, reservoir development, flood control infrastructure, wastewater treatment upgrades, and drinking water system repairs across the state. It’s $20 billion in funded infrastructure work over the next two decades.
For utility and civil contractors in Texas, this isn’t a distant policy story. It’s a project pipeline. The Texas Water Development Board begins distributing funds in 2027, but the applications, designs, and procurement cycles for those projects are being built now. Contractors who will win that work are establishing material relationships, building their vendor networks, and getting familiar with the spec requirements before the jobs go to bid…not after.

Consider what that construction actually requires in aggregate terms. Every pipeline trench needs utility sand and select fill for bedding and backfill. Reservoir construction and flood control work requires rip rap and erosion control material. Water treatment and wastewater facility construction needs crushed stone and road base for site development. Over $150 billion in water, wastewater, and flood infrastructure has been identified across Texas over the next 20 years. Prop 4 funds the first $20 billion of it.
The near-term opportunity is in understanding where the projects are concentrating. Much of the early Prop 4 work will target aging infrastructure in mid-size Texas cities (e.g. communities with deteriorating pipe systems and flood vulnerabilities). Wichita Falls, Abilene, Waco, and comparable markets across Central and North Texas are precisely the kinds of areas this fund was designed to serve.
Contractors already working in water, wastewater, and drainage in these markets are in the strongest position. The ones who aren’t yet should be paying attention to the project lists coming out of the Texas Water Development Board over the next 12 months.
$20 billion in water infrastructure doesn’t move without aggregate. If your business works in utility and civil construction in Texas, this fund is worth understanding before the projects go to bid.
