Secondary lining on the final, easternmost section of London’s super sewer has now passed the 50% mark.
Primary lining of the main tunnel was completed in April 2022 when Tunnel Boring Machine Selina reached the shaft at Abbey Mills Pumping Station.
Now the shutters – the machines used to secondary line – have reached halfway on the 5.5 kilometre stretch between Chamber Wharf, Bermondsey and Abbey Mills.
The shutters, gantries and other associated equipment were also used on the central section of the project and transported to Chambers Wharf by river for reuse on the last section of the Thames Tideway Tunnel.
Secondary lining provides added strength to the tunnel to ensure the super sewer can do its job for future generations while providing a smooth surface over which the sewage flows can travel when the tunnel is up and running in 2025.
At Abbey Mills, the easternmost Tideway site and an existing Thames Water pumping station, the main tunnel will connect to the Lee Tunnel.
Last month secondary lining of the Greenwich Connection Tunnel for London’s super sewer passed Earl Pumping Station – with 65% of its journey to Chambers Wharf now complete.
The shutter machines used to carry out the lining were successfully cleaned inside the shaft at Earl Pumping Station setting the team on its way to its final destination in Bermondsey. This has also allowed the shaft internal walls at Greenwich Pumping Station to be completed.
The Greenwich Connection Tunnel will help tackle the problem of sewage overflow into the Deptford Creek and River Ravensbourne, directing the flows into the new super sewer.
Much of the excavated spoil from the main tunnelling operation was removed from site at Greenwich by barge via in new marine infrastructure in Deptford Creek preventing the need for lorry journeys on local roads.
