Texas Approves $20 Billion for Largest Water Investment in State History
5 Nov
Summary
- Voters approve Proposition 4 to fund water projects over 20 years
- Funding comes from existing state sales tax revenue, no new taxes
- Money to be used for desalination, pipe repairs, water reuse, and more

In a significant move to address Texas' water challenges, voters on November 5, 2025, approved Proposition 4, authorizing the state to make its largest investment in water infrastructure in its 180-year history. The $20 billion funding, to be allocated over the next two decades, will come from existing state sales tax revenue, with up to $1 billion set aside annually starting in 2027.
The proposition aims to expand the overall volume of water available in Texas through various initiatives. These include desalination projects to clean salty water for drinking and agricultural use, fixing leaking pipes, water reuse, and the construction of permitted reservoirs. The funding will also support existing water programs, such as improving flood control infrastructure, ensuring clean drinking water, and promoting agricultural water conservation.
The passage of Proposition 4 reflects the bipartisan recognition of water as a critical resource for the state's survival and economic prosperity. While some environmental groups raised concerns about certain projects, the overwhelming support from Texans demonstrates their commitment to securing a reliable water future for their communities.
