Texas voters recently approved Proposition 4, a constitutional amendment dedicating $1 billion per year in state sales tax revenue to the Texas Water Fund for the next 20 years. The measure passed with 70.42% of the vote, according to the Texas Secretary of State.
According to background information from Texas 2036, a nonpartisan public policy organization, the dedicated revenue will begin flowing in September 2027, when the 2028 fiscal year starts. The money will accumulate in a designated account until lawmakers can appropriate it during the 2029 legislative session, meaning eligible water projects could begin applying later that year.
In the meantime, the Legislature approved more than $2.5 billion for water infrastructure earlier this year — the largest one-time investment in Texas history — to help accelerate planning and construction while the Proposition 4 revenue stream ramps up.
Under Senate Bill 7, at least 50% of the Texas Water Fund must be used to expand the state’s water supply portfolio. That includes desalination, reuse, aquifer storage, reservoir development, and infrastructure expansions. The remaining funds may be used for repairing aging water systems and supporting flood mitigation projects.
Impact on Kingsville
In Kingsville, the long-term funding could help local leaders pursue support for aging water line replacements, system upgrades, leak mitigation, and conservation projects. While specific guidelines are still pending, Kingsville’s ongoing infrastructure needs align with categories the state expects to prioritize.
Statewide investments in desalination and reuse also hold potential benefits for South Texas communities like Kingsville, especially during extended drought cycles or periods of reduced reservoir levels.
Impact on the Coastal Bend
Across the Coastal Bend region, Proposition 4 may influence major water-supply and storm-resilience efforts. Proposed Gulf Coast desalination facilities, including projects connected to the Port of Corpus Christi, fall under the types of new water supply initiatives that must receive at least half of the Water Fund’s resources.
Additionally, regional communities working to address drainage, flooding, and storm impacts may be able to pursue the portion of funding available for infrastructure repairs and flood mitigation.
Local water districts and city officials throughout the Coastal Bend are expected to monitor the Texas Water Development Board’s upcoming guidance to determine which projects may qualify when the application process begins in 2029.
