People in Gomboi and Dwere do not have a source of safe drinking water; they currently walk a quarter mile to a river that tests indicate is highly contaminated with bacteria. In working with the community to develop a plan to build and finance a well/pump installation, we demonstrated how rope pumps work using modified bicycle parts.

The women of Dwere sell clay to earn money for medicine, clothing and school fees. They carry loads of up to 100 lbs on their heads across a river, which can be treacherous. During the rainy season, the river is too high to cross, which limits their earnings. D-Lab is working with the community to construct a low-cost foot bridge.

Groundnuts are a staple food, but shelling nuts by hand is both time consuming and tedious. While there are several low-cost machines that can speed this process up, these devices can require unavailable parts, expensive materials or a high skill level to make. This new design is fast, easy to assemble, and costs less than $7 USD.
