London’s £4.5BN new “super sewer” is now fully connected. With all of its 21 sites brought online, the 25-kilometre Thames Tideway Tunnel is already starting to protect the River Thames from sewage pollution — around five and a half million tonnes of sewage has been diverted so far. Before the new tunnel, heavy rainfall could see London’s combined storm and sewage system fill to capacity, then overflow straight into the River Thames. Now, that material will be diverted into the tunnel and carried out to a treatment centre at Beckton, ultimately leading to a cleaner and more biodiverse river for the UK’s capital. Sitting deep beneath the city’s streets, the tunnel is one of Britain’s most impactful infrastructure projects, but one that most Londoners will probably never see or fully appreciate. Works first started in 2016 when more than 20 deep shafts – some as wide as the dome of St Paul’s Cathedral – were constructed across London to divert sewage flows and to lower tunnelling boring machines (TBMs) into the ground. The primary tunnelling work kicked-off in 2018 and was largely complete by 2022. In May 2024, the new Thames Tideway Tunnel was connected to the existing 7-kilometre Lee Tunnel. The combined system is now known as the London Tideway Tunnel (LTT) and will provide protection for the entire tidal Thames.
