Vote Prop 4 for our Texas Water Future

Pol. Adv. Texas 2036

Building Texas’ water infrastructure for tomorrow

This November, Texans will have a choice on the state’s water future. Proposition 4 on the constitutional amendment election ballot
creates a $1 billion per year state sales tax revenue dedication to the Texas Water Fund.

If approved by voters, this dedicated funding stream will allocate up to $20 billion towards the state’s long-term water infrastructure needs, which include expanding our water supply portfolio, fixing aging systems and building flood protection projects.

Expanding water supplies for a growing, thirsty state

Droughts and population growth will strain Texas’ water supplies. According to the state water plan, Texas faces a long-term water shortage if we undergo a prolonged drought and don't expand our water supply portfolio.
If Texas doesn’t have enough water, then the state will lose billions in lost GDP and over one million jobs.

Fixing failing water systems

Texans endure an average of nearly 3,000 boil water notices per year, as our aging water systems leak enough water to fill an enormous reservoir each year. Left unresolved, aging infrastructure will make water service more unreliable for Texas families.

Did you know?
Texas must invest at least $154 billion over the next 50 years to upgrade aging water systems and meet the needs of our growing population.

Protecting communities from floods

Over the past decade, Texas has endured several catastrophic flood events, including July’s Hill Country Flood, that have taken lives and destroyed communities. Texas’ state flood plan recommends over $54 billion in projects needed to protect communities from flooding disasters.
