Clean Water to Prevent Pandemics in Rhumsiki, Cameroon

Residents in Rhumsiki, Cameroon have water problems. Seasonal rainfall provides inconsistent amounts of water. But of even greater concern is the danger of water-borne diseases. Our project focused on providing a steadier supply of water, and cleaning the dirty water from all of the sources to prevent people in Rhumsiki from getting fatal infectious diseases like cholera. After researching we came up with three possible solutions for cleaning the water: Lifestraw, Lifesaver bottle, and SODIS (SOlar water DISinfection); and one possible solution for extracting water from existing wells: The solar water pump. The least expensive of the filtration technologies is SODIS, so our recommendation for Rhumsiki is to implement this process.https://digitalcommons.wpi.edu/gps-posters/1101/thumbnail.jp

Incorporating Traditional Methods of Irrigation with Water Management in Mandi, India

Access to water is a significant factor for the survival of north Indian farmers situated in hilly areas. These villages often have inadequate surface water sources so they rely on rainwater. Our project\u27s goal was to evaluate traditional irrigation practices in Mandi District in Himachal Pradesh and to design a model to provide farmers at higher altitudes with a sustainable, self- sufficient and cost-effective water management system. Through site assessments and interviews with local farmers, we learned that there is a greater need for drinking water than irrigation water. Therefore, our design utilizes water- harvesting techniques to gather rainwater in a tank that can be used for irrigation or routed through a water-purification system for drinking purposes

Engineering a Bamboo Bicycle

The primary objective of this Major Qualifying Project was to design and construct a bamboo bicycle that could be made available in developing nations and be assembled quickly with minimal training. In order to meet this objective, the project was decomposed into three main components: bicycle joint design, manufacturing fixture design, and safety and testing. The project team was divided into three corresponding groups, utilizing axiomatic design to break down each of the three components. The team successfully manufactured a prototype bamboo bicycle using the Joints Team\u27s system of gussets, the Jig Team\u27s manufacturing fixture, and the bamboo selected by the Safety and Testing Team
