The Water Group focuses on the development and testing of various drinking water source supply, storage and disinfection approaches. Solar-powered pumps installed in a drilled well might be connected to a modest water tower that is disinfected with chlorine bleach. Is this approach to development of drinking water resources sustainable in the developing world? If not, then what approach is best? Would a simpler method of water treatment and safe storage be more appropriate? The Water Group constantly seeks to answer these questions to achieve the best designs possible.
The Latrine Group focuses on the development and testing of various latrine designs that help people get away from their "crap" in developing countries. Major public health benefits result from appropriate latrine use as people are able to break the fecal-oral exposure pathway. Pathogens from feces that come into contact with food, fingers, flies, fluids or fields (the 5 F's) can be easily transmitted to the mouth and can lead to disease. Good latrines lead to good health.
The Energy Group is concerned with all of the electrical design components of chapter projects. For the Ghana Project, they've figured out the electrical requirements of the system based on the needs of the pump and the amount of water estimated to be pumped each day. They used this information to find the number of panels required and also to size other electrical components. Once the number of panels is known, the solar panel support structure can be designed.
Why do the majority of EWB development projects focus on water and sanitation? Because EWB values global community health and wellness. The UIEWB Global Health Group is a relatively new addition to the organization. Members work to improve the health of individuals in Kobriti, Ghana by discussing the community's specific health needs and collaborating with other UIEWB groups to ensure the designs meet these needs.
This past semester, the global health group analyzed community health surveys and led a campus-wide campaign for World Toilet Day to raise awareness of the global need for better sanitation. Moving forward, the Global Health Group hopes to build on the information gained from the surveys and continue to collaborate with the Water and Sanitation Groups to create a community-focused design. Any major is encouraged to be a part of this group!
