 In 1930 the first sewerage plan was prepared to target a population of 20,000 people in Nakasero and Old Kampala areas of the Kampala township.This plan guided sewerage development from 1936 to 1940 in planned urban areas of the Kampala Township and excluded the Kibuga area occupied by the Baganda and other natives.In 1931, the Uganda Railway line reached Kampala, connecting Kampala to Mombasa Port thirty-five years from the commencement of its construction.
