The main objective of the project was to improve the living conditions of the residents of Kampala through the provision of safe and reliable water supply. Package 4B consists of a new Drinking Water Treatment Plant (DWTP) east of Kampala near the village of Katosi as well as a bulk Transmission Main (TM) from Katosi to GKMA’s distribution network. The works were carried out in three phases, and included pre-chlorination, pH adjustment, coagulation, flocculation, clarification, filtration, disinfection, sludge treatment including chemical dosing/storage, sludge treatment, and SCADA.
