Our site in King George’s Park in Wandsworth, is the start of our Frogmore Connection Tunnel, which links the sewer overflows into the main tunnel.

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.
