Our tunnel boring machine (TBM) Selina started her 5.5km journey from Chambers Wharf in early 2021. In April 2022, Selina reached her last stop at Abbey Mills Pumping Station, marking the end of tunnelling for the super sewer.
With the tunnel completed, the team constructed a 24m-wide circular concrete ‘lid’ close to the shaft. In March 2024 the lid was lifted and moved into position on top of the shaft. At 12,000-tonnes this manoeuvre represents the heaviest lift on the super sewer project – even surpassing the lifting of Tideway’s six tunnel boring machines early in the programme.
