London’s new Super Sewer has reached 10km as the first section of the main tunnel has been completed.
Four tunnel boring machines (TBMs) are currently at work deep beneath the city to create the main tunnel and two connection tunnels, with two more set to begin work next year.
On Friday, TBM Millicent reached the finish line in Fulham, having completed a 5km section of the tunnel between Battersea and Fulham.
Paul Hallows, site manager at Kirtling Street in the central section, said: “We celebrated two key milestones last week as we hit the 10km mark and completed the first section of the main tunnel, from Battersea to Fulham.
“We are getting closer every day to our goal of a cleaner River Thames and creating a better environment for London, its wildlife and its inhabitants.”
Ursula – the TBM creating a central-London section of the super sewer between Battersea and Bermondsey – is nearly 3km into its journey, having passed Parliament – as well as Vauxhall, Lambeth and Westminster bridges – and soon the iconic London Eye.
The TBM building the western section of the tunnel, named Rachel, is more than 1.5km into the journey from Fulham to Acton.
Elsewhere, a smaller TBM, Charlotte, has completed the southern section of a connection tunnel linking Wandsworth to the main tunnel.
Earlier this month, Tideway launched a new, interactive map that shows the location of its four TBMs, which are all named after inspirational women who lived or worked near Tideway sites. Visit https://www.tideway.london/tbm-tracker/ to see the map.
