Univ. of Texas El Paso’s researchers developing water filter to help colonias


Maricela Reyna and her family pay property tax on their home, located in an El Paso County colonia. Yet they lack access to municipal water and gas services. Instead, they hire a tanker truck to deliver water each week, and buy propane for cooking.

City trash trucks do not run down the unpaved road outside Reyna’s home, either. Instead, she shells out $80 a month for a private hauler to take the family’s waste.

“And if you don’t pay within 10 days, they don’t service you no more. It’s crazy,” Reyna said.

A colonia, or residential area along the Texas-Mexico border, typically lacks basic necessities such as potable water and sewage treatment. About 60 percent of colonia residents in El Paso County live below or near the poverty line, with a median annual income of about $29,000. By contrast, about 40 percent of all El Paso county families live below or near the poverty line, according to the Dallas Federal Reserve Board.

More than 400,000 Texans live in colonias.

Maria Sotelo, whose home is in a San Elizario colonia, must drive 15 minutes simply to find a patch of green space where her teenage sons can participate in sports.

“We need places where the children can play,” said the 40-year-old Sotelo, as she stood in the community’s only “playground”—an overgrown field bordered

by a stable filled with goats and a horse.

“Children come here but the weeds are too high and they cannot play,” said Sotelo, pointing to outdated metal swings. “My father would bring me here when

I was a child, and nothing has changed. We need a park.”

An even more pressing for many colonia residents, though, is the need for safe drinking water. Studies find that improved water quality decreases the number and seriousness of gastrointestinal illnesses and rashes people experience.

In response, faculty and graduate students at UTEP are collaborating on a $500,000 grant to develop an affordable and user-friendly water filter, specifically designed for colonia homes that rely on 2,500 gallon tanks for their water supply.

Civil Engineering Prof. Shane Walker is principal investigator on the project, which will…
