SEWAGE
  • Overview
  • Pumping Stations
    • Sewage Pumping Stations are used to pump sewage from low collection points in built-up areas within cities to Sewage Treatment facilities for treatment. As most Sewage Pumping Stations are within built-up areas, work often involves deep structures next to existing structures and requires expertise in design and installation of temporary shoring works, deep excavation and dewatering systems. Some notable projects are the 200,000PE PS12 pumping station in Putrajaya and the 210,000PE PS16 pumping station in Georgetown, Penang.
