HDPE Answer To Drought Crises

West Texas Town Receives State Aid For Water Pipeline
Ballinger, TX—Images of polyethylene pipe curving across the west Texas landscape while a massive ditcher carves a slice out of the parched earth might seem like just another construction story. In reality, however, the pipeline is part of a State of Emergency Relief Effort passed by the governor of Texas to rescue the city of Ballinger from severe drought.

A 14-mile, 10-inch, high-density polyethylene (HDPE) pipeline is under construction that will bring water from the Abilene-Ivey pipeline (a raw water pipeline that provides water for the city of Abilene) to the Ballinger supply lake, which has slowly dried up over the last seven years. The city, which serves a little over 5,000 people, hopes that this will be a temporary fix until the lake fills back up. If the lake does refill, then the pipeline will only be used as a backup source. The Office of Rural Community Affairs (ORCA) and the Texas Commission on Environmental Quality (TCEQ) are funding the $700,000 project.

West Texans have always considered water to be a precious commodity. Texans fiercely defend their water privileges by remaining the only state in the U.S. that guarantees landowners the right to gather as much water as they want from directly below their land. In fact, the entire panhandle is concerned that this law will make it possible for anyone who owns land in the panhandle to siphon the Ogallala Aquifer from beneath them and sell it to a metropolitan area in another part of the state.

The severe drought that has gripped the region for the last several years has inspired many city officials to explore a wide variety of conservation methods. For the city of Ballinger, the solution is high-density polyethylene pipe (HDPE).

“We plan to have the whole town's water distribution system replaced with polyethylene within the next 10 years,” said City Administrator Tommy New. “If you're going to ask people to conserve water, it just makes sense for the city to do the same thing and not let it leak from the distribution system.”

HDPE is the only water piping material that has a 0% leak rating; the city of Ballinger has previously used about 3 miles of it to rehabilitate a subdivision. In the three years since the first HDPE installation, there have been no reported leaks within the new system.

The city of Ballinger is not alone. According to the EPA, many parts of the country do not have enough water to meet the needs of cities, farms, and the environment, even under normal rainfall conditions. The drought over the last several years has increased competition for limited water supplies, and the Interior Department has even developed what they call a hot spots map. It is a map that details areas that are potential spots for water wars much like the Klamath River basin in Oregon in 2001. That dispute was between farmers and environmentalists over low river levels that endangered salmon populations. It is still in federal court.
