Rain water is the one clean source of water in Tanzania. We have a lot of roof space but no way to collect the abundant rain water at the moment. We need a "guttering" system and a large Poly-Tank (10,000 Lt) . . . this will allow the home and school to collect clean, drinkable water for the children. Water borne diseases are the major cause of intestinal disease here and many children die needlessly . . . the collection of rain water is a clean renewable resource . Help us now.
