Chennai’s Sewage system relies heavily on pumping stations because of flat terrain and limited natural gradients. Many stations had operated continuously for decades and required rehabilitation to address mechanical wear, electrical inefficiencies and capacity constraints. The project focused on strengthening and modernising critical pumping stations that form the backbone of the city’s wastewater conveyance system. Detailed condition assessment, identification of structural, mechanical and electrical deficiencies and development of rehabilitation strategies were undertaken to improve reliability, efficiency and safety while minimising service disruption.
