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 tunneling for the super sewer. The tunnel boring machine has now been removed from the shaft and transported off site. 

Until Summer 2023, 24-hour working is taking place as we add a secondary lining of concrete onto the inside of the tunnel. A batching plant has also been set up to supply the concrete.

You can learn more about our Abbey Mills site by watching our Tunnel Vision episode on YouTube.

Until Summer 2023, 24-hour working is taking place.

The Tideway construction site sits within an existing Thames Water Pumping Station site. Once Tideway finishes construction work the site will remain a Thames Water owned and operated site. 

Marina Willer of design studio Pentagram has been commissioned by Tideway to create a bespoke bronze plaque for Abbey Mills Pumping Station. It forms part of her wider commission for the design of 12 floor-based bronze plaques at sites across the main tunnel route to celebrate the transformational importance of the tunnel.
