Tideway is upgrading London’s sewer system to cope with its growing population.
Our 25km tunnel will intercept, store and ultimately transfer sewage waste away from the River Thames.
All six Tunnel Boring Machines have now finished their drives marking the completion of the tunnelling phase of the project.
