Solapur’s underground Sewage system, developed in the late nineteen sixties, was increasingly unable to handle rising wastewater volumes driven by population growth and expansion of water supply services. Large portions of the city remained unsewered and existing networks suffered hydraulic inefficiencies and frequent overflows. The project involved a detailed study of the existing sewer network, drainage patterns and topography to optimise gravity flow and minimise dependence on pumping so that reliability could be improved and operational costs reduced. New drainage basins were defined, and existing sewers were strategically rerouted to improve system efficiency.
