Our 20 man team worked with local engineers, technicians, and community members in Honduras to assess water problems and select feasible solutions. During the brigade, I had the opportunity to assess potential water sources, map and survey community land, plan and design water projects, and provide technical follow-up on completed systems. Utilizing software such as LOOP and MapSource we were able to simulate the water flow and pressure at system nodes.
