Rachel, one of our six TBMs (and one of four building the main tunnel), will begin her 7km journey west to Acton Storm Tanks, with all the excavated spoil being removed by barge. This site will also ‘receive’ Millicent, the TBM building the 5km section from Battersea, as well as Charlotte, which is building the smaller Frogmore Connection tunnel between Wandsworth and Fulham.
Reconnecting London with the River Thames
London relies on a 150-year-old sewer system built for a population less than half its current size. As a result, millions of tonnes of raw sewage spills, untreated, into the River Thames each year.
That’s where we come in.
We’re building a 25km Super Sewer under the Thames to intercept those nasty spills and clean up our river for the good of the city, its wildlife and you.
