Available clean drinking water is a major problem in Madagascar. This is where the Safe Water Cube comes in. 38 Safe Water Cube wells were installed in schools in the Antsirabe region. Thanks to its five-stage mechanical filtration, this fountain can deliver around 1000 liters of clean drinking water per hour without electricity, without chemicals and without maintenance. In this way, the students get clean drinking water, but also their families. Because in the evening, every school child brings a canister with 20 liters of drinking water home. The wells are also accessible to the neighboring population. As a result, illnesses could be greatly reduced.
