The Uganda Rain Water harvesting project is supported by Rotary Clubs of Winnipeg West, Whitby (Ont), Eglington (Ont) and Mondetta Charity Foundation (MCF). It is situated at Kamwokya Primary School which is situated in the large slum of Kampala, the capital city of Uganda. The school has a student body of 1900 even though it was built for 1000 students. Along with Kampala Capital City Authority (KCCA), MCF erected an annex on the school compound of three stories/nine classrooms to alleviated the crowding in the classrooms which at times had in excess of 100 students. This large student body requires a lot of water. Therefore MCF decided to harvest water from the roofs. This project includes of harvesting the water, storing in tanks and provide it for the benefit of students and teachers. This will also reduce the expense for the school which buys water from City Council.
