Tideway: The “Super Sewer” Transforming London

In recent years, London has witnessed one of the most iconic infrastructure initiatives in modern Europe: the Thames Tideway Tunnel, also known as the city’s “super sewer.” With a budget of £1.5 billion, this large-scale engineering project aimed to modernize the Victorian-era sewer network, drastically reducing wastewater discharge into the River Thames and enhancing the city’s environmental sustainability.

Protecnium’s Involvement: Technical Excellence in Action

The Central Section of the project was executed by the Ferrovial – Laing O’Rourke Joint Venture, involving the construction of 12.7 kilometers of tunnel using two Earth Pressure Balance (EPB) tunnel boring machines with a diameter of 8.8 meters, along with eight strategically placed access shafts.

From January 2018 until the end of construction, Protecnium was proud to support the project by providing over 40 highly qualified technical professionals, covering all phases—from TBM excavation to Shotcrete Lining (SCL) tunnel construction.

Key Technical Profiles Provided

• Shift Managers.
• TBM and SCL Engineers.
• Control Room and Quality Engineers.
