6 October 2012 SAN ANGELO – With its pretty rivers and lakes, this city of 95,000 people is sometimes called the oasis of West Texas. But San Angelo recently came within a year of running out of water, as it faced a severe drought that produced brown lawns, dying bushes and fear. “Who wants to pull up to a hotel and it’s dead?” said Bob Banskter, general manager of the Rodeway Inn in San Angelo, referring to the state of the landscaping. It was late September, a day after City Council members had voted to ban the use of outdoor sprinklers, and as he walked around the hotel, Mr. Banskter pointed out shrubbery that was sure to die without watering. What a difference a few days make. Last weekend the heavens opened, and it poured. More than five inches of rain fell on San Angelo. Drought-stricken Midland, an oil boomtown more than 100 miles to the northwest, got more rain on Sept. 28 than on any other day since 1968. A severely low reservoir that supplies both cities with water more than doubled its reserves. On Friday, San Angelo’s City Council voted to reverse the sprinkler ban. But the drought in West Texas is not over, and experts say this perennially dry region must plan carefully. The two-year drought, the region’s worst in more than half a century, has starkly exposed its vulnerability. Farmers, swimming pool cleaners, carwash operators and many others depend on ample water, and if supplies are short, jobs can be lost. Pressure is growing on the Legislature to address the problem when it meets next year, especially because the population continues to grow and West Texas is projected to become drier. “What happens now is we have the attention of the public and the elected officials,” said Ken Rainwater, the director of the Water Resources Center at Texas Tech University. Texans need to learn to value water properly, Mr. Rainwater said, and that may mean building new water-supply projects and easing up on lawns in West Texas, which at best receives half the rainfall of East Texas. Before the rains, the situation had been dire. O. H. Ivie, the main remaining reservoir supplying Midland, Odessa, San Angelo and other towns in the Permian Basin of West Texas, had been projected to run out of water as early as next summer, which would have forced cities in the area to rely on newly tapped supplies or to truck in water. But with the rain, it swelled from 12 percent to 26 percent full in just four days. E. V. Spence, another reservoir that has been essentially empty for months but sends water, when available, to the Midland-Odessa area, also revived slightly. John Grant, the general manager of the Colorado River Municipal Water District, which operates both reservoirs, said the rains had brought Permian Basin cities more than a year of water. “We’re pretty excited,” he said. “But we’re not out of the drought.” Some 66 percent of the state remains in drought. That is a major improvement from a week ago, but the Texas Commission on Environmental Quality still says 23 communities, many of them in West Texas, could be within 180 days of running out of water. Meteorologists say that El Niño, the Pacific Ocean current pattern, could appear this fall for the first time in more than two years. Normally that brings above-average rainfall and cooler temperatures to Texas, especially the southern end of the state. However, “it’s looking like a disappointing El Niño,” said John Nielsen-Gammon, the state climatologist, who is based at Texas A&M University. He says the state has a 40 percent chance of above-normal rainfall this fall and winter but a 25 percent chance of its falling below normal. Texas remains in the grip of a long-term drought that could still last several years, he said. This drought has forced local officials in West Texas to make agonizing decisions. At San Angelo’s City Council meeting on Sept. 27, before all the rain, officials voted to continue to allow carwashes to operate and swimming pools to be filled despite the looming shortages. […] The city is building a $120 million pipeline project southeast of town that will tap an aquifer called the Hickory. It should be operational next summer, officials say, and will initially be able to carry two-thirds of the city’s basic wintertime needs, with deliveries increasing over time. The catch is that the aquifer water contains higher levels of radium than federal standards allow, so it must be diluted with reservoir water until a treatment plant can be built. Another major new West Texas pipeline, costing $135 million and running 42 miles from the Odessa area to water well fields to the west, is also moving along. Next week workers should finish laying the main pipeline, according to Mr. Grant of the Colorado River Municipal Water District, which is overseeing the project. The water should be available in December, he said. Some cities close to salty aquifers are looking toward desalination; Odessa is aggressively pursuing this, although the process is expensive. The concept of water reuse is also catching on quickly in West Texas, including the prospect of turning human sewage into drinking water. A $12 million water reuse plant is scheduled to begin operating in February in Big Spring, pumping well-scrubbed sewage into the drinking-water systems of Midland, Odessa and Big Spring. […]

Even After Rains, Facing Long-Term Water Needs
