The final, easternmost section of London’s new super sewer is now having its secondary lining installed, following the completion of the primary lining in April.
Secondary lining will continue on the final 5.5km stretch of the tunnel between Bermondsey and Abbey Mills Pumping Station into next year.
Primary lining was completed for the entire super sewer back in April – now, with much of the secondary lining elsewhere complete, the team at Chambers Wharf has begun the final, easternmost stretch.
The secondary lining is required to provide added strength to the tunnel to ensure the super sewer can do its job for generations to come, while providing a smooth surface over which the sewage flows can travel when the tunnel is up and running in 2025.
