London’s super sewer hits another milestone

Official Project Partner : Tideway

The mammoth task of creating London’s new super sewer is well underway with a key milestone recently completed.

This month saw the first Tunnel Boring Machine (TBM) launch shaft excavated, at 60m deep, some 45,000cu m has been removed from the Kirtling Street site. In keeping with Tideway’s commitment to use the Thames to transport over 90% of materials to and from Tideway sites, the spoil was removed by barge along the river.

Works to begin construction of the walls of the shaft began in June last year, with excavation starting in late November. Preparations are now underway for the next phase of the project, which involves creating the lining of the launch tunnels, laying the groundwork for the TBMs to enter later this year.

Chris Darton, Tideway’s Central Delivery Manager, said: “Completing the shaft marks a major milestone in the delivery of the super sewer which will clean up the River Thames. The team worked tirelessly to complete the excavation and we are now looking forward to welcoming our giant Tunnel Boring Machines to site ahead of tunnelling starting later this year.”

Construction of the Thames Tideway Tunnel, a major infrastructure project which will tackle sewage pollution in the River Thames, has been divided into three sections – East, West and Central – with each section being built by a different joint-venture. The central section is being constructed by a joint venture of Ferrovial Agroman UK and Laing O’Rourke Construction.
