Project phase II

Project phase II – Rainwater cistern and water treatment for the girls’ accommodation

In addition to sanitary facilities we focus on water supply for the students. A common rainwater cistern will be built for both usable and potable water, from which the required quantities of water can be taken. In the case of water scarcity, a higher priority is to provide water for drinking, so that waste of this valuable resource can be ruled out.

The water is treated with a proven concept, the slow sand filter, used in our previous project at Ssama Primary School in 2014. Rainwater is collected from the roofs of the sanitary and cistern buildings. To remove coarse dirt the water is passed through a leaf filter before entering the cistern. The water then is fed into an elevated tank via a solar-powered pump. From there it flows into the sand filters by hydrostatic pressure. The sand filters remove dirt and microorganisms such as bacteria and algae from the water. The treated water is fed into an extraction tank and also into the tanks supplying the sanitary building. In order to guarantee long-term water quality, the treated water continuously circulates from the tanks of the sanitary building to the cistern and back through the sand filters.
