ABSTRACT Runoff management has been every city\342\200\231s concern for many years all over the world and storm water management is often referred to as the redheaded stepchild of municipal government. However, it continues to be a major problem for most city engineers and planners as they are faced with a challenge of improving performance in the operations of the drainage and wastewater collection systems in Botswana. This paper analysis the effects of the storm water infiltration into sewers on the economics of sewer designs and as well as on the quality of wastewater reaching the Gaborone Wastewater Treatment Plant (GWTP). The main objective of the work was to investigate whether or not the wet weather conditions could affect the design flows and wastewater quality at the Wastewater Treatment Plant. This was achieved by comparing flow rates and wastewater quality during Dry and Wet Weather conditions.
