Poly student’s project provides disaster relief
A Cal Poly student recently was awarded a $14,500 grant by the Clinton Global Initiative and the Wal-Mart Foundation for her work on a portable water treatment system for disaster relief zones. Tricia Compas, a 24-year-old graduate student in environmental engineering, dedicated more than 2,000 hours to her thesis project, the Polytech Waterbag. The long, cylindrical bag allows victims in disasters to scoop up water from flood zones and other sources where it’s potentially contaminated and then add cleansing chemicals that make the water drinkable. The Tribune - Cal Poly grad student Tricia Compas, left, along with business student Chris McCann, her advisor Dr. Yarrow Nelson, and fellow environmental engineering students Stephen Barr, and Imran Rahman hold a prototype of the Polytech Waterbag.Compas — who traveled to New York and briefly met former President Bill Clinton to receive her honor — has worked with a team of students and an advisory panel of professors and business professionals. Compas and the team are working with relief organizations to make sure the water meets safety standards. They’re also working to patent and market the Waterbag, which provides enough water to last a family of four 10 days. The mostly plastic Waterbag provides the container to carry and to keep the disinfected water clean. The bag, which can be carried like a backpack, also has an integrated filter. “There have been so many disasters recently from the earthquake in China to the hurricanes,” Compas said. “Disaster relief organizations say that providing people with drinking water is their No. 1 problem.” The idea for the project came from Cal Poly professor Tryg Lundquist, who submitted a winning application to Cal Poly’s Innovation Quest 2007 contest along with Cal Poly students Dan Frost and Steve Barr. “Millions of people are affected by major floods in most years,” Lundquist said. “Relief agencies should be able to provide waterbag treatment kits more quickly and at lower cost than the 5-gallon jugs that are the norm now. Speed is essential because victims need to drink.”Compas decided to take on the Waterbag project in part because of her interest in global environmental projects. She has participated with Engineers Without Borders and worked on a water treatment system through that organization for a village in Thailand. The goal for the current project is to create enough Waterbags to assist 100,000 families in 2009 and 500,000 in 2010. She and her team will be testing the bag using test water provided by the U.S. Environmental Protection Agency, and the data they gather will help decide whether to consider the Waterbag for field testing. “The lab phase of this work should be done by the end of the school year,” Lundquist said. Compas said that it has been a thrill to participate in a project with potential worldwide benefits. And while in New York this fall during the three-day conference where Clinton presented her with the award, she also enjoyed meeting engineers, government officials and business leaders all working toward eliminating poverty. “I was honored to represent Cal Poly, and both humbled and inspired by all the leaders working on these issues day in and day out,” Compas said.
