Thames Water has selected a preferred bidder to deliver the £4.2bn Thames Tideway Tunnel, also known as the ‘super sewer’.
The event took place on 13 July 2015 at the Institution of Civil Engineers in London. The newly-created, special purpose company Bazalgette Tunnel Limited, whose shareholders are a consortium of investors comprising funds managed by Allianz, Amber Infrastructure Group, Dalmore Capital Limited and DIF, is in line to own, finance and deliver the landmark project.
Along with the recently completed upgrade of five sewage treatment works on the tidal Thames (including at Beckton, East London), both the Lee Tunnel and the Thames Tideway Tunnel are needed to stem the 39 million tonnes of untreated sewage that overflow into the tidal river in a typical year from the capital’s overstretched, Victorian sewerage network.
The tunnel will stretch 25 km (15 miles), largely beneath the bed of the River Thames, from Acton in the west to Abbey Mills near Stratford in the east. There it will join up with the Lee Tunnel, currently under construction by Thames Water.
