Thames Tideway

Nearly 170 years after Sir Joseph Bazalgette revolutionised the way water waste flowed through London, work has begun on the new 4.2bn super sewer which is urgently needed to halt the tonnes of sewage being spilt into the tidal section of the River Thames every year. Currently, around 10,000 tonnes of sewage-related litter enters the tidal River Thames from CSOs every year. This will be reduced by 90% once the Tideway Tunnel is in operation in 2023.
