Heathwall Pumping Station is an existing Thames Water site, and just a short walk from our Kirtling Street site in Battersea. Here, we’re working to ‘intercept’ the South West Storm Relief and Heathwall Pumping Station combined sewer overflows (CSOs), which together spill more than 800,000m3 into the River Thames in a typical year – our work will help to reduce this by 93 per cent.

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.
