Store, Harvest, Fix: How Texas Can Save Its Water Supply
Bad news: Texas is running out of water.Good news: There are several solutions local and state leaders can take to make sure we don’t.The state’s water supply is threatened by a changing climate, rapid population growth, and outdated infrastructure, which loses billions of gallons of water each year. Texas’ water demand is growing. By 2070, the state is projected to need an additional 7.7 millionacre-feet of water per year to meet the needs of residents, farmers, and industries if strategies are not implemented.The answers to our water crisis range from the traditional (think reservoirs) to the innovative (think desalination).The Texas Water Development Board has recommended more than 2,400 water management strategy projects to increase water supply. The cost to implement those strategies is estimated to be $80 billion (in 2018 dollars) by 2070, not including inflation. No single solution can meet all of Texas’ water needs. And it will not be cheap. Water experts say policymakers must invest wisely, ensuring the most cost-effective and sustainable solutions are prioritized.Here’s a look at some of the solutions and their pitfalls.Many water experts say that conservation is the first line of defense. Cyrus Reed, a longtime environmental lobbyist at the Texas Capitol and conservation director for the state’s Sierra Club, called conservation “the most conservative and lowest cost approach” to meet our water needs.Conservation means using less water and using it more efficiently. That could look like reducing household and business water consumption through incentives, leak detection, and water-efficient appliances, improving irrigation techniques to minimize water loss, or encouraging industries to recycle water and reduce overall use.One example is in El Paso. Since the 1990s, the city has had a toilet rebate program that has helped residents conserve water and save money on monthly water bills. The program offers a $50 rebate for customers who purchase water-efficient toilets that use 1.28 gallons per flush, as opposed to older toilets that use as much as six gallons per flush.So far, they’ve given 54,000 rebates to their 220,000 customers, which includes homes, businesses and government agencies.“Conservation is often underutilized due to the need for behavior change and the lack of regulatory enforcement,” said Temple McKinnon, a director of water supply planning at the water board. Fixing old infrastructure One of the obvious solutions — at least to water experts — is to fix the state’s aging water infrastructure. Leaking pipes and deteriorating treatment plants have led to billions of water being lost. In 2023 alone, 88 billion gallons of water were lost in Texas’ most populous cities, according to self-reported water loss audits submitted to the Texas Water Development Board.“The most efficient water source that we have is the water that we already have,” said John Dupnik, a deputy executive administrator at the Texas Water Development Board.Jennifer Walker, director for the Texas Coast and Water program with the National Wildlife Federation, said that fixing the infrastructure creates new water supplies because it’s water that wouldn’t be delivered to Texans otherwise.“Anything that we can do to reduce waste is new water,” Walker said.The Texas section of the American Society of Civil Engineers released their infrastructure report card last month. Texas received a D+ for drinking water, with the report emphasizing the role of aging infrastructure and the need for funding for infrastructure operation and maintenance.One reason why the state’s water systems have fallen behind is costs. Most water systems are run by cities or local agencies, which have tried to keep water rates and other local taxes low. This is particularly true in rural Texas communities that have smaller populations and tax bases. Texas 2036 has estimated the state’s water agencies need nearly $154 billion by 2050 for water infrastructure.State Sen. Charles Perry, R-Lubbock, has proposed a bill that could dedicate millions for new water projects. His emphasis is on what water experts call “new water supplies.” One example is removing salt from seawater or brackish groundwater through a process called desalination, which makes water drinkable.Most communities need to increase their water supply, especially as existing supply may be dwindling or face uncertainty, said Shane Walker, a professor at Texas Tech University who serves as the director of the Water and the Environment Research Center.Desalination is one of the most promising solutions, Walker said. Texas is rich in both seawater along the Gulf Coast, and brackish groundwater, with underground reserves of salty water.He said cities and towns shouldn’t wait to tap into desalination until there are no options. “Start now before you’re in a jam,” Walker said.Coastal cities like Corpus Christi are turning to seawater desalination as a drought-proof water source. While desalination plants are expensive to build and operate, the gulf region provides a large supply of water. By 2030, Texas is recommended to produce 179,000 acre-feet of desalinated seawater annually, increasing to 192,000 acre-feet by 2070, according to the latest state water plan. That’s enough water to support about 1.1 million Texans for one year.Texas also has vast reserves of brackish water underground, and cities like El Paso have already pioneered its use. The Kay Bailey Hutchison Desalination Plant is the largest inland desalination plant in the world. At max capacity, it can produce 27.5 million gallons of drinking water daily from brackish groundwater in the Hueco Bolson Aquifer. It also produces 3 million gallons of concentrate, which is the leftover water containing all the salt and impurities that was filtered out. A pipeline sends the concentrate more than 20 miles from the plant where it is injected underground.However, desalination comes with challenges: First, the process requires large amounts of energy to push water through membranes that separate salt and impurities, which is expensive. Then there’s the disposal of concentrated brine, a highly salty liquid that’s a byproduct of desalination. It must be carefully managed to avoid harming marine ecosystems or the environment.“It’ll always come back to the concentrate disposal,” said Art Ruiz, chief plant manager for El Paso Water and the former manager of the city’s desalination plant. “No matter how small or how big (the plant), you’re going to create a byproduct.Recycling every drop of water is another solution. Water reuse allows treated wastewater to be reclaimed for various purposes, from irrigation to industrial cooling.One way of reusing water is direct potable reuse, which involves treating wastewater to drinking-water standards and either reintroducing it directly into the water supply or blending it with other sources before further treatment. Indirect potable reuse follows a similar process, but first releases treated water into a natural reservoir or aquifer before being re-extracted for use.Lubbock has recently started this practice with Leprino Foods, the world’s largest mozzarella cheese producer. The company opened an 850,000-square-foot facility in January and will produce 1.5 million pounds of cheese a day. In return for the water the company uses, Leprino will return around 2 million gallons of clean water to Lubbock every day. This accounts for about 6.25% of Lubbock’s daily water use.Leprino said they installed substantial capacity for water storage so the company could recover and store more water from the manufacturing process before it is cleaned.“In Lubbock, we’ve designed and constructed the facility with water stewardship in mind from day one,” Leprino said in a statement.El Paso is leading the way with its Pure Water Center Facility, which recently started construction. It will purify already treated wastewater for people to drink and deliver 10 million gallons daily. When it’s operating in 2028, it will be the first direct-to-distribution reuse facility in the country. While the concept, “toilet-to-tap” might seem unappealing at first, water utility experts say the advanced treatment process ensures the water is clean and safe.San Antonio has embraced reuse for non-drinking water, sending treated wastewater from the city’s Steven M. Clouse Water Recycling Center back into the city and its rivers. Purple-marked pipes carry recycled water to irrigate golf courses, cool industrial towers, and sustain the downtown River Walk. Some is diverted to an energy plant, while the rest flows to the gulf. In dry times, this steady outflow keeps the San Antonio River running. Aquifer storage and recovery Aquifer storage and recovery is exactly what it sounds like. A water utility can store excess water underground during wet periods, allowing it to be withdrawn during droughts.El Paso has a program that injects treated water into the Hueco Bolson aquifer for future use. San Antonio stores excess Edwards Aquifer water in a certain site within the Carrizo Aquifer during wet periods, then recovers it during droughts. This method reduces evaporation losses compared to above-ground reservoirs and provides a reliable emergency water supply.However, this process requires specific geological conditions to be effective, and not all areas of Texas have suitable aquifers for storage. In some cases, it can also take a long time to move water through all the levels underground to reach the aquifer.One method being explored is creating and using playa lakes to recharge aquifers. Playas are shallow lakes that form in arid, flat regions and catch rainwater runoff. They are dry more often than wet, which is how they function — the water seeps through cracks in the dry soil of the playa’s basin.“Every time a playa dries out and we get a rain event, that’s when recharge happens,” said Heather Johnson with Texas Parks and Wildlife in Lubbock. “You’ll get about three inches of rainwater infiltration into the playa basin annually.”Johnson said for every four acres of playa basin, approximately one acre-foot of water is recharged — about 326,000 gallons of water. That’s enough water to cover a football field with nine inches of water.Ducks Unlimited, a nonprofit national organization that manages wetlands and habitat conservations, is working with Texas Parks and Wildlife in the High Plains to recharge the Ogallala Aquifer. Tavin Dotson, the first regional biologist in the region for Ducks Unlimited, said playa lakes store a seed bank and when playas fill, plants begin to grow. This creates a grassy buffer around the playa — which acts as a natural filter to wash out contaminants before water reaches the playa basin and aquifers.Most of the Ducks Unlimited work in Texas is in the coastal areas. However, Dotson said there is a push to get the practice going even more in the High Plains, where the Ogallala Aquifer is facing declining levels.One of the practices involves filling pits and ditches that disrupt how playas function. Filling the pits allows playas to properly retain and filter water. Johnson said the High Plains contains more than 23,000 playa basins.Rain harvesting — capturing and storing rainwater for later use — is another way of conserving. This technique provides a decentralized water source for irrigation and livestock. While rainwater harvesting is an effective conservation tool, it is limited by Texas’ variable rainfall patterns. It rains more in East Texas as opposed to the West. Still, some Texas groundwater districts actively promote rainwater harvesting to reduce reliance on municipal supplies.High Plains Underground Water Conservation District in Lubbock — the first groundwater district created in Texas — monitors water use and levels in the Ogallala, Edwards-Trinity and Dockum/Santa Rosa Aquifers. The organization also encourages ways to conserve water, including rainwater harvesting. In recent years, the water district has helped raise awareness of the practice in the region. The district gave away ten rain barrels and 12 rain chains in 2023.“They are constructed in the landscape to help mitigate some of the runoff that was occurring at the arboretum,” Coleman said. “They’re nicely constructed. There’s cobblestones and other nice features to make it a nice looking part of the landscape.”Historically, Texas has relied on reservoirs to store and manage water — a solution that boomed after a devastating drought that lasted seven years in the 1950s.There are more than 180 across the state. However, building new reservoirs has become increasingly difficult due to land constraints, environmental concerns, and the high costs of construction.Despite these challenges, regional water planning groups proposed 23 new major reservoirs in the 2022 state water plan. However, new laws now require realistic development timelines and feasibility studies, meaning that reservoirs may not be seen as the go-to solution they once were.Matt Phillips, the deputy general manager for the Brazos River Authority, told lawmakers during a House committee meeting that the population for the basin will double by 2080. The river authority serves Waco, Georgetown, Round Rock, College Station and other cities. Phillips said they would need an additional 500,000 acre-feet of water to meet those demands.“All the cheap water is gone,” Phillips said. “Every drop of water we develop from here on is going to be exponentially more expensive than anything we’ve seen in the past, so we’re going to need help to get there.”State Rep. Cody Harris, R-Palestine, filed legislation that would promote reservoir projects. Perry’s Senate bill mirrors the proposal for reservoirs. In both, the water development board would be able to use money from the Texas Water Fund to encourage regional and interregional project developments. This includes the construction of reservoirs and stormwater retention basins for water supply, flood protection and groundwater recharge.This story was originally published by The Texas Tribune and distributed through a partnership with The Associated Press.Copyright 2025 The Associated Press.

Texas lawmakers are poised to devote billions to save the state’s water supply, but there's debate over which strategies to invest in
