Tideway completes final shaft for London ‘super sewer’

Construction of the Thames Tideway Tunnel has reached a major milestone following the excavation of a 60m deep shaft at the King Edward Memorial Park site in Wapping.

The shaft is the deepest and the last of 21 shafts to be excavated for the “super sewer” project which involves constructing a 25km tunnel under the River Thames. The shaft’s concrete base slab will be poured within the next month.

Tideway’s work at the King Edward Memorial Park site will divert sewage into the new sewer as it passes below.

As well as building the shaft, Tideway is extending the Tower Hamlets park with new land for terraces and seating. To mark the progress, Tideway has released aerial images showing the scale of the work on site.

Tideway construction engineer Harriet Cheaney said: “These helicopter images not only give us amazing views of our beautiful city, but showcase the scale of the work Tideway is doing to clean up the River Thames.

“We’ve now built around 20km of the 25km super sewer and are around 65% complete – but these amazing photos really bring the scale of our task to life.

“With this final shaft now complete, teams across Tideway have an eye on the finish line and are working around the clock to complete this job and clean up the River Thames.”

The expansion of London’s sewer network is happening across 24 construction sites in the capital. As well as the King Edward Memorial Park site, the new images show progress at Chambers Wharf, Chelsea Embankment Foreshore, Blackfriars Bridge Foreshore, Deptford Church Street and Victoria Embankment.

Earlier this month, a 700t tunnel boring machine (TBM) named Ursula was hoisted from a 60m deep shaft at Tideway’s Bermondsey site.

Tunnelling on the western section of the project was completed in September 2020.

When complete in 2025, the project will prevent tens of millions of tonnes of sewage from polluting the river every year. In addition, the new land reclaimed from the river will be landscaped and available as completely new public space.
