Here at our Chelsea Embankment site, our work will clean up one of the most polluting overflows by connecting the old discharge point into the new super sewer. This involves building a 50m deep shaft to intercept the current combined sewer overflows (CSOs) outside the Royal Hospital Chelsea, and taking that flow down into the new sewer below the river. Alongside our works we will also create a new area of public space by the river, for everyone to enjoy.

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.
