Aerial photographs from the company building London’s super sewer, Tideway, have revealed new pockets of land to be created in the Thames as part of the subterranean project.

With tunnelling complete on the £4.2 billion project, focus has shifted to connecting the new system, a secondary lining, testing works and putting the finishing touches on above-ground public spaces that will open once the project is complete in 2025.

However, given the capital’s limited space, Tideway has had to build out into the Thames to house new infrastructure and create said spaces along its embankment.

Recently released photos and artists’ impressions demonstrate both project progress thus far and what Londoners can look forward to in the coming years.

“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,” Clare Donnelly, lead architect on the Tideway project, said.

Work on the 2.5m diameter tunnel which stretches for 25km and plunges to depths of up to 70m below the capital, began in 2018. Boasting a 120-year design life, the project will create an additional 1.6 million cubic metres of additional storage in London’s sewers.

According to Tideway figures, in a typical year around 40 million m2 of untreated sewage is dumped into the tidal Thames across more than 50 occasions – almost once a week on average. This is something the new tunnel will aim to tackle while helping to improve water quality and allowing marine life to thrive.

As reported by Utility Week, however, in March 2022 Ofwat changed the licence for the project to reflect the impact of Covid-19 pandemic on costs and the fall in interest rates since the project began.

Customers will absorb a greater proportion of the additional costs relating to work being suspended at the start of lockdown but will no longer be exposed to changes in interest rates.
