Guttering often is the weak link in the performance of a rainwater catchment system. Most of the time, collected rainwater is spilled before reaching the cistern. Problems range from gutter maintenance to its design. This paper addresses design issues, locally available materials and the relationship between rainfall intensity and roof area to gutter cross-sections area, shape, slope and length. Special consideration is given to aspects of gutter technology in developing countries.

The paper also recommends suitable measures for promoting rainwater harvesting techniques in drought prone areas of Uganda and other developing countries.
