| valign="top" | - High runoff coefficient is good, enabling water to collect very well from small rains <br>
Once a year, the reservoir may be left to dry out for a short period to reduce the danger of bilharzia (a human disease caused by parasitic worms called Schistosomes). The reservoir, silt traps, gutters, etc., must be de-silted at least once a year. To control mosquito breeding and the spread of malaria, Tilapia fish can be introduced in the reservoir (every year if it runs dry).

|'''AKVO RSR Project:''' [http://www.akvo.org/rsr/project/440/ Raising awareness on rainwater harvesting]
Uganda still has a lot to do in order to meet the MDG on water and sanitation. Rainwater harvesting is a viable option for the provision of clean water but has been greatly down-played by the ministry of water and development actors. Uganda Rainwater Association has been advocating for its promotion and RAIN Foundation came in to support URWA in these activities.
