Thames super sewer project creates ‘new land’ just as Bazalgette did

The Thames Tideway Tunnel will be a 25 km combined sewer running mostly under the tidal section of the River Thames across Inner London to capture, store and convey almost all the raw sewage and rainwater that currently overflows into the estuary.

Stunning new aerial photography shows the extraordinary changes being made to the banks of the River Thames as part of London’s super sewer project.

With tunnelling complete on the 25km sewer that will clean up the Thames, the focus is now turning to connecting the system and working on the above-ground public spaces that will be left once the project is complete in 2025.

With space at a premium in London, Tideway has had to build out into the Thames to house the new infrastructure and, in the process, has created a number of architecturally beautiful spaces along the embankment.

These new spaces are now being turned into a combined three acres of public space – giving Londoners and visitors all-new public spaces for the first time in over a century.

Clare Donnelly, Lead Architect on the Tideway project, said: “Creating new public spaces in the heart of London is an incredible opportunity and it’s so exciting after all these years to see these spaces coming to life.

“New public spaces in Wapping, Blackfriars, Victoria, Vauxhall, Nine Elms, Chelsea and Putney will benefit Londoners and visitors to the city for generations to come, and we can’t wait for them to open.”

When Sir Joseph Bazalgette built London’s sewerage network in the 1800s, he had to build out into the river to house his brick-lined tunnels, above-ground spaces that are known as Victoria, Albert and Chelsea Embankments.

Tideway is building on that legacy today and, much like Bazalgette’s, these public spaces will provide new destinations for Londoners and tourists alike.
