The consortium comprising Ferrovial Agroman and Laing O'Rourke will build the central section of the Thames Tideway Tunnel, London's new sewer infrastructure, for 746 million pounds, equivalent to over 1,050 million euro.

The part to be built by the consortium, with a diameter of 7.2 metres, is divided into two sections. Both commence at Kirtling Street: the first, 5 kilometres in length, runs east to Carnwath Road. The second, 7.7 kilometres long, runs west to Chambers Wharf. Measuring 12.7 km, the central section is the largest component of the tunnel, which will measure 25 kilometres in total. The contract also includes building 8 shafts between 42 and 62 metres deep, 6 connecting tunnels, sewers, interceptors and valve rooms.

Once the project has been delivered, Ferrovial Services' UK subsidiary, Amey, will integrate the information and communication systems for project operation, maintenance and control.

Costing 4.2 billion pounds, the Thames Tideway Tunnel will avoid the discharge of untreated sewage  from 34 identified 'combined sewer overflows' into the tidal Thames River. It is vital for the future of London's sewer network, which must cater for a growing population.  The building works will start in 2016. They are expected to be completed in seven years’ time.

This contract increases the list of infrastructure projects that Ferrovial Agroman is delivering in London. The company also has a key role in the Crossrail project by constructing the tunnels between Royal Oak and Farringdon, the caverns for Tottenham Court Road and Bond Street stations, and Farringdon station. It is also building the extension of London Underground's Northern Line and built the Queen's Terminal at Heathrow, which was inaugurated in the summer of 2014.
