Laing O'Rourke JV wins £140m Beckton sewage treatment job

A joint venture between Laing O’Rourke and Imtech Process has secured a £140 million contract for the upgrade of the Beckton Sewage Treatment Works extension.

The Tamesis JV will carry out the work as part of a £190million project at Beckton, the largest sewage treatment works in Europe, to help clean up the River Thames.

Construction work is expected to start this spring.

The upgrade at Beckton, due for completion in 2014, forms part of Thames Water’s London Tideway Improvements programme.

This is made up of three major schemes:

  • the £600million Lee Tunnel project
  • the proposed Thames Tunnel
  • a £675million investment to improve London’s five principal sewage treatment works including Mogden, Crossness, Long Reach and Riverside

Thames Water’s Chief Operating Officer Steve Shine said: “This expansion marks a fundamental step in improving the quality of London’s iconic river, while also serving the future needs of London and achieving significant environmental benefits, including reducing odour.

“This work will enable us to fully treat 60 per cent more sewage arriving at the site during heavy rainfall, and allow for a 10 per cent population increase until 2021.

The improvements will enable the site to treat 60 per cent more sewage than it does now, so it can:

  • fully treat increased flows during heavy rainfall, which currently discharge as storm sewage into the River Thames when the site becomes overloaded to prevent streets and homes from flooding;
  • treat additional storm flows from the Lee Tunnel, a new four-mile sewer which will capture storm sewage that currently overflows into the River Lee when the sewerage system gets overwhelmed during heavy rainfall.
  • The expansion has also been designed to accommodate additional flows from the proposed Thames Tunnel.
