Abstract | Due to Botswana's flat topography and sandy pervious soils, the availability of surface water sources is limited and generally inappropriate for providing rural water supplies. This paper considers the use of rainwater as a\AB supplementary water source. Although the use of formalized rainwater catchment systems, such as roof catchment tanks, supposedly dates back to the turn of the century, its capacity was limited because of poor design. This paper\AB discusses the enormous potential of an improved and extended rainwater catchment system in urban Botswana. Estimates of roof runoff supply of housing stock and government buildings in Gaborone emphasize the need for rigorous\AB implementation of a rainwater catchment programme. This paper also looks at the problems of water quality and discusses computer-aided design (CAD) and the limitations of computer modelling. |
