Sewage released into London's waterways for 12,000 hours in last year, City Hall finds
Sewage has been discharged into London’s waterways for more than 12,000 hours in the last year, according to a new analysis by City Hall.
The finding came as mayor Sadiq Khan reaffirmed his manifesto promise to make all the capital’s waterways swimmable by 2034, saying it would follow on from the “progress we have made in cleaning our air”.
City Hall officers said sewage was released by Thames Water into the capital’s rivers for 12,105 hours and 38 minutes in the year to the end of March 2024.
