A. These roof tiles are actually solar panels. They are south facing and will generate much of the electricity for the school.
B. Rain water will fall onto the roof, flow to the gutter, and then into this large water cistern.
C. This pipe will connect to a plumbing system in the building, and the water will be used for everything except drinking water. (Hand washing, dish washing, irrigation, etc).
D. When water levels are low this pipe will be used, and water will be pumped up to the sinks.
