Texas pushes major water infrastructure investment as population growth strains supply

As Texas braces for record population growth and rising concerns over drought and aging water systems, voters will soon decide on Proposition 4, a constitutional amendment that would allocate up to $1 billion annually for water infrastructure projects statewide. 

According to Spectrum News, the measure, on the November 2025 ballot, would direct funds to the Texas Water Development Board to support initiatives that expand water supply, repair outdated systems, and improve drought and flood resilience. Supporters argue the amendment will create long-term stability in funding as communities face escalating water demand from both urban expansion and industrial development.

At the North Texas Municipal Water District (NTMWD), which supplies water to more than 2.3 million residents across Collin County and the rapidly growing Dallas suburbs, officials say new infrastructure is essential to keep pace with regional growth. The district’s Wylie Water Treatment Plant—a key hub spanning over 500 acres—represents the type of project that could benefit from state funding as it expands to meet future needs, Spectrum News reported.

Advocates, including public policy groups such as Texas 2036, say Proposition 4 would ensure a consistent, long-term investment pipeline for water projects in both rural and metropolitan areas. Critics, however, have raised questions about oversight and environmental safeguards. Regardless of the outcome, Texas continues to prioritize upgrades to its water systems to support growth, reliability, and sustainability across the state.
