  Super-sewer mobilisation starts

Super-sewer mobilisation starts

29 August 2015 Email this article

Contractors are starting to mobilise for the construction of London’s £4.2bn super-sewer.

Following Ofwat signing off the deal between Thames Water and project licensee Bazalgette Tunnel Ltd, construction contractors are now being mobilised to start work on London’s £4.2bn super-sewer. The firms working on the sewer will be:

West contract: BMB JV (BAM Nuttall, Morgan Sindall and Balfour Beatty)

Central contract: FLO JV (Ferrovial Agroman UK, Laing O’Rourke Construction)

East contract: CVB JV (Costain, Vinci Construction Grands Projects and Bachy Soletanche)

Amey has been awarded the system integration contract and will be responsible for providing process control and communication equipment and software systems for operation, maintenance and reporting across the Thames Tideway Tunnel system once commissioned.

It is estimated that the Thames Tideway Tunnel project will create more than 9,000 direct and indirect jobs at the peak of construction.

The Thames Tideway Tunnel will stem the flows from the 34 'combined sewer overflows' (CSOs) identified by the Environment Agency as the most polluting. The £4.2 billion project will connect up with the Lee Tunnel. This has already been constructed by Thames Water to take wastewater otherwise destined for the river to Beckton sewage works, East London, from early in 2016.

Andy Mitchell, CEO at Tideway, the delivery organisation for the Thames Tideway Tunnel, now owned by Bazalgette Tunnel Limited, said: “Our task over the next seven years is quite simply to make sure London has a sewerage system capable of meeting the capital’s modern-day needs. Everyone in the team is excited and can’t wait to get started.

“It’s not just about cleaning up the river, important though that is. Nor is it just about building a tunnel. It’s about making sure we transform the River Thames, making it central to the capital’s wider social and economic well-being. This is a once in a generation opportunity and we are determined to raise the bar in every way, not least the way we treat local communities potentially most directly affected by construction works.

“Through our commitment to remove excavated materials by barge, the opportunity to rejuvenate the river as a transport artery will be a particular focus for us.”
