Started in 2002, Engineers Without Borders (EWB) is an international non-profit humanitarian organization that works to provide basic necessities to communities in need. Lehigh's chapter of EWB started in 2007. The goal of EWB is to provide clean water, education, sanitation, and renewable energy by focusing on low cost, high impact projects. To promote sustainability we partner with host communities on projects so that the communities can manage the systems autonomously in the future. Lehigh's chapter primary efforts are in San Juan del Sur where we are implementing a water system at the Free High School for Adults.
