In order to halting sewage from entering the River Thames, Tideway has activated the new super sewer in London, UK, whereas the final of 21 connections between the Victorian sewers and the 25km Thames Tideway Tunnel was made after 10 years of construction, which’s advantage is bringing the system online and preventing sewage pollution in the tidal Thames.
The responsibility of delivering the Thames Tideway Tunnel is up to Tideway, owned by a consortium of investors.

Thames Water’s 15 million customers are the responsibles of funding this tunnel’s £4.5bn cost.
According to Tideway CEO Andy Mitchell: “This is another significant step forward, with this final connection complete, the super sewer is fully up and running and protecting the Thames. Our next step is to test it in storm conditions, which is why we are keeping a close eye on the weather, and we will do this over the coming months.”
Forming the London Tideway Tunnel (LTT) system,this super sewer with 25km length links to the existing 6.9km Lee Tunnel, a Thames Water asset. Autumn 2024 was the date that the full system went online.
Construction began in 2016, with work taking place across two dozen sites from Acton in west London to Abbey Mills Pumping Station in east London.
With the aim of diverting sewage flows and lower tunneling machines underground, over 20 deep shafts were built across London.
While the 2018 was the date of commencing first giant tunneling machine’s work, primary tunneling on the 25km main tunnel and two smaller connection tunnels was completed by 2022.
Autumn 2023 was the date of ending secondary tunnel linings across all tunnels, with the heavy civil engineering work wrapped up by spring 2024.
While a consortium of contractors is responsible to deliver the Tideway project, the west region is handled by a joint venture of BAM Nuttall, Morgan Sindall Infrastructure, and Balfour Beatty and the central region is managed by Ferrovial Agroman UK Laing O’Rourke and also the Costain, Vinci Construction Grands Projets, and Bachy Soletanche are responsibles for the east region.
