This is the central point of the 25km super sewer and is the largest site on the entire project. Located next door to Battersea Power Station, from here we are tunnelling both east and west to connect the sites along the route. Located within one of the busiest construction areas in London, our shaft here, where we have started tunnelling, has a diameter the same size as the dome of St Paul's Cathedral.

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.
