We all know kids have boundless amounts of energy and a need to play – so why not channel some of that energy into much needed rural infrastructure? That was the brilliant idea behind the PlayPump: a humanitarian design project that consists of a water pump hooked up to a small village merry-go-round. Access to clean drinking water is a huge concern in developing regions of the world, and now the PlayPump system is bringing clean water into the hardest hit regions of Sub-Saharan Africa, where it has been installed in rural villages and primary schools, so that kids can have fun while pumping all the clean, potable water that their families need.
