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. The Project comprises: a. tunnels: i. a main tunnel which will capture and store combined sewage from CSOs along its route and transfer it to Abbey Mills Pumping Station, from where the Lee Tunnel will transfer it for treatment at Beckton Sewage Treatment Works ii. 11 connection tunnels, which will link flows from CSOs to the main tunnel. b. Worksites: i. five main tunnel Worksites (drive and/or reception sites) ii. 16 CSO Worksites iii. two System modification Worksites Thames Tideway Tunnel iv. works at Beckton Sewage Treatment works. The Main Works West - Contract 405: all works from and including the Acton Storm Tanks shaft to and including the Carnwath Road Riverside shaft, as well as the Frogmore connection tunnel from Carnwath Road Riverside shaft to King George’s Park shaft.
