The Columbia University chapter of Engineers Without Borders aims to address the problems facing people both locally and overseas by leveraging the skills, talents, and passions of Columbia University students and the sponsorships formed with our organization. Our members come from many different arts, sciences, and engineering backgrounds, who collectively share a desire to do meaningful work and make a difference.
The chapter currently consists of three programs in Ghana, Uganda, and Morocco. The Ghana program, which started in 2004, used to work in the semi-urban town of Sakyikrom but now focuses on water management in the farming community of Obodan. In 2008, the Uganda program was established to install a Multi-Function Energy Platform in the Soroti region. The Morocco program, which began in 2011, finished building a bridge in the rural community of Ait Bayoud in June 2013 and is now and is now working on providing safe and easily accessible drinking water directly to the communities of Izgouaren and Ilguiloda through a water sourcing and distribution system. Each project draws from the skills of its members to provide technical solutions to worldwide problems.
To address the flooding of the Tagawowt river, the community suggested a bridge project to EWB-USA CU so that the river could be safely and consistently crossed during the rainy season. Along with professional structural engineers, various Peace Corps volunteers, and a host of community leaders and workers in Ait Bayoud, the students of the Morocco project have worked to fund, design, and source materials for the implementation of a 210ft suspension footbridge.
In the summer of 2011 and the winter of 2012, two assessment teams gathered technical data and determined a bridge site. In the summer of 2012, implementation of the bridge began. Over the course of 6 weeks, our team of students and professional mentors worked alongside local workers in Ait Bayoud to clear and prepare the bridge sites, mix and pour the concrete foundations and towers, and install each of the bridge's main cables. In the winter of 2013, we sent a team to assess the state of the bridge, and in the summer we sent two final project teams. They tensioned the bridge cables, installed decking, and completed the project. Following the bridge’s completion in June 2013, CU-EWB Morocco has maintained and improved the completed footbridge, performing extensive inspections every six months and successfully pre-tensioning a new rope in the summer of 2017. Teams have recently focused on fully transitioning ownership and maintenance of the bridge to the community, creating a useful picture-based guide and facilitating community-led bridge inspections.
Ait Bayoud consists of a series of dwars, or neighborhood clusters, that are staggered along the river. Izgouaren, a dwar isolated on a raised plateau, suffers from limited access to water. Every day, families walk back and forth down to the river to gather water from a nearby spring, spending about an hour per trip and making up to 3 trips a day.
To address this issue, a team consisting of Columbia students as well as Peace Corps Volunteers visited Izgouaren in January 2014 and began to assess the dwar's needs, the river conditions, and Ait Bayoud's current water sourcing status. We sent one additional assessment travel team in the summer of 2014 to measure the flow rate of multiple springs and the river near Izgouaren, to determine a piping path to transport water to the dwars, and to perform water quality tests on the sources of water. Using the information collected during the two assessment trips, the winter 2015 team returned and successfully constructed a shallow well along the river.
As of summer 2019 we have constructed a concrete water storage tank, installed solar panels to power a pump at the well, and laid approximately 4km of HDPE pipeline between the wellsite, concrete tank and the Ilguiloda dwar, which lies between the pipeline and Izgouaren. Tap stands accessible by the Ilguiloda community have also been constructed. The COVID-19 pandemic precluded in-person implementation in the summer of 2020, which led us to focus on community development and building relationships with local organizations. Extension of the pipeline from Ilguiloda to Izgouaren is postponed until travel restrictions are lifted. Additionally, we intend to construct two more tanks, one as a break pressure and the other a storage tank including a slow sand filter, and construct tap stands to ensure all community members have access to the water.
