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.
