AECOM to Design Largest Stretch of London’s Super Sewer

AECOM announced that it has been selected as design consultant for the central section of the Thames Tideway Tunnel in London – dubbed the “Super Sewer.” At 12 km (7.5 miles), the central section is the longest of three main work packages. AECOM is working for the delivery partner, joint venture of Ferrovial Agroman UK and Laing O’Rourke.

The central section runs from Carnwath Road in Fulham to Chambers Wharf in Bermondsey. Construction is expected to start in 2016 and be complete by 2023. Tunneling will be accomplished by two TBMs. Ground conditions are expected to include London clay, Lambeth group, Thanet sands and chalk.

The overall alignment stretches 25 km from west of London to Limehouse, and then to the Abbey Mills Pumping station, where it connects to the Lee Tunnel and the Beckton Sewage Treatment Works. AECOM also provided design services for the Lee Tunnel, which is due to be complete in 2016.

The other delivery partners are BAM Nuttall, Morgan Sindall and Balfour Beatty Group (West section) and Costain, Vinci Construction Grands Projects and Bachy Soletanche (East section). The $1.6 Thames Tideway is being built to upgrade London’s Victorian era sewers for the next 100 years and more and enable the United Kingdom to meet European environmental standards.
