The report will be launched at an upcoming event to be held by the utility company at the end of May in London. The event - Why London's River needs the Thames Tunnel - will highlight the environmental case for the proposed "supersewer".
Combined Sewer Overflow discharges are now one of the last major sources of pollution to be found in the tidal River Thames. The report will examine the impact of sewage from London's over-stretched sewage network polluting the capital’s river and how it affects the wildlife in and around the Thames Tideway. Thames said the report will also highlight the ecological benefits of the Thames Tunnel and why its construction is essential to help protect and sustain the ecosystems within the Thames Tideway.
Speakers at the invitation-only event will include Tony Juniper, environmentalist, writer and sustainability adviser, Roger De Freitas, Hammersmith Society, West London River Group and Thames21 and Jill Goddard from the Thames Estuary Partnership.
Head of the Environment Agency Lord Chris Smith recently described the proposed tunnel as a necessity, not an option. The tunnel has also received strong support from other quarters, particularly environmental organisations.
With the UK government demanding a 50% reduction in storm overflow spills by 2029, the era of reactive management is over. Speaking in the House of Commons on 21 July 2025, then environment secretary Steve Reed said, “This Government will cut water companies’ sewage pollution in half by the end of the decade.”
