Global STEM Squads mobilizes students abroad to improve access to clean water in rural under resourced communities through applying STEM skills. Volunteers work alongside local engineers to assess, design, and construct infrastructure projects that range from rainwater harvesters that supply drinking water for local schools to large scale community-wide water systems that pipe water directly into households. STEM Squads is a program of Global Brigades, a highly recognized international development organization that uniquely implements a Holistic Model that targets specific UN Sustainable Development goals within partner communities. Our model systematically builds community ownership and collaboratively executes programs with the end goal of sustainably transitioning to a relationship of impact monitoring.
