Is Beckton Sewage Treatment Works capable of coping with the additional load the London Tideway Tunnels will put on it?
The proposed tunnels are designed to store excess flows linked to rainfall. Only after the flows in the existing network have subsided will the flows from the London Tideway Tunnels be pumped out for treatment at Beckton Sewage Treatment Works. The storage capacity of the tunnels will be optimised to avoid the need for excessive treatment capacity. Additional capacity will be provided at Beckton Sewage Treatment Works to fully treat the flow from the tunnels, as well as enabling the plant to treat more sewage from the existing catchment and to improve treatment standards.
