London’s Thames Tideway Tunnel project, known as the “Super Sewer,” has reached a milestone with the completion of its underground construction.
The installation of a 24-metre diameter and 1200-tonne concrete lid at Abbey Mills Pumping Station marks the final step.
Sarens, a global heavy-lifting and engineering transport company, played a key role in this operation.
The tunnel, spanning 25 kilometres with a diameter of 7.2 metres, aims to reduce sewage pollution in central London’s River Thames.
Once operational in 2025, it’s expected to minimise annual storm sewage spillage.
The project, a joint venture involving Costain, Bachy Soletanche and Vinci under Tideway, has been ongoing for eight years.
