The Thames Tideway Tunnel project (the Project) will control CSO discharges by intercepting and diverting combined sewage flows into a new storage and transfer tunnel. The main tunnel will run from Acton Storm Tanks in west London to Abbey Mills Pumping Station in the east, where it will connect to the Lee Tunnel, which will transfer the combined sewage to Beckton Sewage Treatment Works for treatment. The Project extends from Acton Storm Tanks in west London, to Abbey Mills Pumping Station in east London. The Project includes associated works at Beckton STW, Shad Thames Pumping Station and Bekesbourne Street. The geographic layout of the Project and local authorities through which it passes is shown in Figure 1.
