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. The team has recently completed adding a secondary lining of concrete onto the inside of the tunnel. Read our latest site information sheet here about the upcoming work on the site  - October 2023. 

The team are now undertaking large concrete pours at the bottom of the shaft to create large concrete shapes that will help channel the sewage flows.  

At surface level the cover slab for the shaft has been constructed. It will be lifted into position on top of the shaft in early 2024.

At Abbey Mills 24-hour working is taking place on site. The main period of 24-hour working will last until March 2024 inside the tunnel and at the base of the shaft. There will be a final element of 24-hour working in May 2024.

Above ground works are taking place during weekdays: 8am – 6pm, with limited activities to support the 24-hour working in the tunnel and shaft continuing on the surface 24-hours a day.

The Tideway construction site sits within an existing Thames Water Pumping Station site. Once Tideway finishes construction 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.
