At our site in King George’s Park in Wandsworth, Charlotte, one of our six tunnel boring machines (TBMs), will be lifted from the ground after tunnelling from Dormay Street, around 500m north.

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.
