Oregon Episcopal School InvenTeam• The invention is designed for Niger, Africa, where the water table is extremely low. • The pump can be built with indigenous materials and can be repaired by a bicycle mechanic—a common profession in Niger. • The students consulted <Mercy Corp http://www.mercycorps.org/> to learn about the social and cultural considerations for the pump design. • As the users pedals the device, a drum rotates and lowers one bucket into a trough to collect the water; as the user revises the pedaling motion the second bucket lowers and fills with water. • The InvenTeam plans to polish the prototype and test it in Niger.
