MVB is a joint venture consisting of three of the country’s leading civil engineering contractors: Morgan Sindall, VINCI Construction Grands Projets and Bachy Soletanche.
The team is constructing the four-mile Lee Tunnel which will help prevent 16 million tonnes of sewage entering the River Lee each year during heavy rainfall. This is a result of London’s Victorian sewers not being able to cope with a twenty-first century city which has trebled in size and continues to grow.
The seven-metre diameter tunnel — the width of three London buses — will capture discharges following heavy rain from London’s largest combined sewer overflow at Abbey Mills Pumping Station in Stratford. The tunnel will transfer the flows to Beckton sewage works, which is being expanded by 60 per cent to deal with the increased volumes. The tunnel will reach depths of up to 75 metres.
The Lee Tunnel is one of three schemes that make up Thames Water’s London Tideway Improvements programme, creating a cleaner, healthier River Thames.
Construction begin in September 2010 and tunnelling work is expected to finish by the end of 2013. The project should be completed by 2015. For more information, please visit the project website here.

Our first steps in the UK were made in 1992 with the construction of the second bridge on the Severn Estuary, a cable-stayed bridge connecting England and Wales. Our branch in London was established to ensure the development of local long-term partnerships based in the UK.
In addition to the Lee Tunnel project, our teams are currently working on the Liverpool Street and Whitechapel station tunnels for Crossrail C510, on the new Whitechapel Crossrail station (C512) and they completed in February 2012 the advanced works for Tottenham Court Road Crossrail station (C421).
Our prime goal is the design and construction of major infrastructure and complicated structures, working in partnership with our British and Irish colleagues. VINCI Construction Grands Projets is part of VINCI, the world leader in concessions and construction.
