This article is part of Running Out, an occasional series about Texas’ water crisis. Read more stories about the threats facing Texas’ water supply here. It will also be updated through the legislative session as bills advance.

Texas’ water supply is full of uncertainties.

Leaking water pipes and deteriorating infrastructure plague the state’s water systems. Prolonged droughts and record-setting heat waves are depleting the state’s rivers. And a growing population is adding more stress to the system every day.

One state figure estimates there could be a severe shortage of municipal water by 2030 if there is recurring, record-breaking drought conditions across the state, and if water entities and state leaders fail to put in place key strategies to secure water supplies.

State lawmakers have proposed several possible solutions. Their proposals range from committing to annual funding for water projects to tapping into new sources, like oil and gas wastewater that comes from the ground during extraction, and making sure the quality of drinking water is safer.

There are a number of steps to the legislative process, however, and they all have to take place before a bill can go into law. There are 10 bills the Tribune is tracking — some of them have moved quickly in the legislature, while others have failed to pick up steam. Here are the steps of the process we are tracking:

Bill has been filed: This is the very first step in the process. A bill is written and introduced in one of the two legislative chambers, the Texas House or state Senate.

In the works: Bills are assigned to committees where a panel of lawmakers vet the bill and take testimony from the public. Bills must be approved by at least one committee before the full chamber votes on it. Both chambers have to approve a bill for it to become law. A bill may also go to a conference committee to reconcile any differences between the chambers on the bill before it’s passed.

Passed the House: The bill received a majority vote of approval by state representatives. If it is a House bill, it must go to the Senate next for approval. If it has already passed by the Senate, then it is sent to Gov. Greg Abbott.

Passed the Senate: The bill received a majority vote of approval by state senators. If the bill starts in the Senate, it will go to the House for approval. If it’s already been passed by the House, then it is sent to Abbott.

Signed into Law: Bills signed by Abbott become law. If there is a bill left unsigned but was not vetoed by Abbott, then it automatically becomes law.

Vetoed or failed: A legislative proposal failed by missing a key deadline or did not make it out of the original committee for a floor vote. Abbott could also veto any bills sent to him.

Here are the bills to follow:

Senate Bill 7 — A priority bill that establishes an administrative framework for how water projects — including building of infrastructure that would transport water across the state and fixing leaking pipes — would be funded under the Texas Water Development Board. The bill would also establish the Texas Water Fund Advisory Committee for oversight and the Office of Water Supply Conveyance Coordination to improve regional and statewide water infrastructure connectivity.

Bill has been filed.

Senate Joint Resolution 66 — A constitutional amendment to dedicate $1 billion to the Texas Water Fund for up to 16 years beginning in 2027. The annual stream of state tax dollars and insurance premium taxes would help cities and local water agencies buy more water and repair aging infrastructure. It calls for 80% of the appropriated money to go to the New Water Supply for Texas Fund — prioritizing desalination projects and pipelines transporting water from the water-rich regions of Texas to arid, drought-stricken areas. The other 20% would go to fixing aging infrastructure. The bill would expire in 2043.

In the works. Bill has been referred to a Senate committee on finance.

House Bill 16 — A sweeping priority bill that touches on water funds, flood plans, and the development of infrastructure to transport water into a water supply system. The bill would also create the Texas Water Fund Advisory Committee to oversee operations on each fund and report to the Texas Water Development Board.

In the works. Bill has been referred to a House committee on natural resources.

House Joint Resolution 7 — A constitutional amendment to dedicate $1 billion to the Texas Water Fund for up to 10 years. The annual stream of state tax dollars would help cities and local water agencies buy more water and repair aging infrastructure. It gives the Texas Water Development Board full discretion over the $1 billion, allowing it to distribute the money as it sees fit.

In the works. Bill has been scheduled for a public hearing.

House Bill 1501 — Directs the Texas State University Meadows Center for Water and the Environment to study how Texas can develop seawater desalination plants along the Gulf Coast. Desalination is the process of removing salt from seawater or salty groundwater so it can be used for drinking water, irrigation and industrial uses. The study will examine international desalination plants in Israel and Australia to identify best practices and challenges, including financial barriers and explore ways to dispose of brine — highly salty and concentrated liquid — including its potential use in nuclear energy production. The findings must be reported by Jan. 1, 2027.

In the works. Bill has been referred to a House committee on natural resources.

House Bill 310 — A bill that directs the Texas Water Development Board, the state agency that oversees water supplies and projects, on how to allocate money from the Texas Water Fund. The board would ensure a portion of the money is used for water infrastructure projects and prioritized by risk or need. It would go to rural areas with less than 20,000 people, and areas with at least 20,000 residents but no more than 150,000. It also calls for money to be spent on a statewide public awareness campaign about water.

In the works: Bill is pending in a House committee on natural resources.

Senate Bill 1145 — Authorizes the Texas Commission on Environmental Quality to issue permits for land application of produced water — wastewater that comes out of the ground during the extraction of oil and gas production — and develop standards that prevent pollution of surface and groundwater.

Passed the Senate: The House has received the bill for review.

House Bill 2080 — A bill that calls for the Texas Commission on Environmental Quality to appoint a panel to review the duties of a groundwater conservation district. This would happen if someone files a petition with the TCEQ requesting an inquiry about a conservation district. If the petition is not dismissed, the commission would appoint a review panel of five members.

Bill has been filed.

House Bill 2114 — This bill aims to prevent conflicts of interest by barring engineering firms involved in state or regional water planning from also constructing reservoirs. It specifically applies to feasibility reviews assessing costs, timelines, land acquisition, and economic impacts. One example of a case is the $7 billion Marvin Nichols Reservoir, which groups estimate would flood over 66,000 acres of northeast Texas forest. A feasibility review released last year found no major obstacles to the project. The firm that conducted the review, Freese and Nichols Inc., is also set to build the reservoir.

Bill has been filed.

House Bill 1400 — Creates a new fund to support scientific research that will expand knowledge about the quality, quantity and threats to the state’s groundwater resources. It will be administered by the Texas Water Development Board.

In the works. Bill has been scheduled for a public hearing.
