On 29 April, Tideway marks the end of tunnelling for London’s Thames Tideway Tunnel or ‘Super Sewer’ and to commemorate this engineering feat, with a live performance 70 metres underground in the depth of the tunnel itself.

Tunnelling started in 2018. The tunnel, now constructed, runs 25km from east to west London and at its deepest is around 70m deep. Once complete, the new super sewer will dramatically reduce sewage pollution of River Thames.

The Tideway project is due to be complete in 2025, following secondary lining, connection and testing works.
