Making drinking water safe for a college town in Bolivia
Fairfield University School of Engineering project reduces illness in rural community
Having access to safe drinking water and ensuring it remains sanitary is an uphill battle in many corners of the globe. It's a major priority right now for a rural farming community in northwestern Bolivia where many have been sickened by unclean water.
That is where a group from Fairfield University's School of Engineering has been working to improve drinking water conditions at the Unidad Academica Campesina (UAC), "the united college for the peasants." Residents in the lush, warm jungle region have reported a 50% reduction in stomach distress since work was done there on service trips made by the Fairfield engineering group with a student chapter of "Engineers Without Borders" from South Dakota State University.
One of the team's projects has involved chlorinators - devices that destroy bacteria and other organisms that can lead to disease. Thanks to their efforts, two chlorinators at UAC were implemented to provide safer drinking water treated to World Health Organization (WHO) standards for developing countries.
"In Bolivia, there is minimal infrastructure for water and wastewater treatment overall," said Bruce Berdanier, Ph.D., professor and dean of Fairfield University's School of Engineering, who helped lead the two-week service trip to UAC, the second such trip in the past year. (He was formerly professor and department head of Civil and Environmental Engineering at South Dakota State, so that is the reason for the collaboration.)
"There's also a lack of resources, such as money, tools, personnel, replacement parts, adding to the maintenance challenges there," Dr. Berdanier continued. "This was an opportunity to teach students how engineers can collaborate to design new systems, fix problems and provide service to people less fortunate than us."
Three Fairfield mechanical engineering majors and one math major accompanied Dr. Berdanier on the recent trip to Carmen Pampa. Many residents and students there have been afflicted with stomach distress due to the poor drinking water quality. Because of expansive growth of the student population at UAC, the school has had challenges with providing adequate potable water systems.
With financial assistance from the Fairfield Rotary Club, the Fairfield group focused their energies on installing and fixing two chlorinators. "We will not be able to get their drinking water to U.S. treatment standards with our current projects, but we can make it a lot better," said Dr. Berdanier.
For the students, they learned firsthand how engineers can make a difference.
"It's a rewarding job," said Katherine Pitz, a senior mechanical engineering major from Lagrangeville, N.Y., of her second trip to the college. "I like how you can see your work benefitting a community. I also enjoy the connections that I've made through this project, the people I have met, and I enjoyed being immersed into a different culture."
Kaitlin Maciejewski, of Fairfield, Conn., was not only travelling abroad for the first time, but undertaking her first service-learning trip. Fairfield, a Jesuit institution, places a high priority on service projects. "I have always planned on doing volunteer work, such as Engineers without Borders, Teach for America, or volunteering abroad, and this experience solidified those plans."
School of Engineering classmates James Brendan McGlew and Sean McGuinness helped Pitz and Maciejewski work on the second step for drinking water treatment necessary in developing countries. That is, they did survey work for planned slow sand filters, comprised of layers of sand and gravel that remove pathogens from contaminated water.
"One thing I did that I have never done before was survey between water sheds," said McGlew, a senior mechanical engineering major from Briarcliff, N.Y.
The work is vital. Current United Nations' estimates indicate that 780 million people still lack access to clean drinking water and 2.5 billion people do not have access to proper sanitation.
Due to extensive farming in the area – and the cutting down of the tropical jungle to make room for crops – runoff into the rivers containing contaminated soils has greatly impacted some of the drinking water intake locations. This poses a threat to area homes. That's because most people have a water line running to their houses that contain untreated river water. The fulfillment of future service projects to install sand filters and protect water sources will help to address those concerns.
The students said they look forward to returning to the Bolivian community, which has been appreciative of their work.
"Bolivia was a great experience and I think more of the engineering students here should look into doing it," said McGlew. "You won't get another chance like it."
Maciejewski agrees. "I really want to go out into the world and use my skills learned in school to do good," said the math major with a minor in engineering. "I would jump at the chance to go on a trip, or even just work on research domestically for a trip like this, again."
