New London 'Super Sewer' Project Getting Under Way as First Consignment of Tunnel Rings Arrive

An Addition Designed to Last for Two Centuries
Shipping News Feature

UK – The much vaunted 'Super Sewer' which is the Thames Tideway tunnel moved a step closer as the first train load of primary tunnel precast rings arrived at Hutchison Ports London Thamesport. Despite the astonishing feats of engineering in Victorian times by Sir Joseph Bazalgette and his team the capital's expanding population has meant an upgrade to the system has become essential.

The new giant sewer will upgrade London's current sewage network to cope with demands well into the 22nd century and reconnect the city with the iconic River Thames. 6,000 precast rings, of which those in this consignment are the first, will initially be transported by rail from the manufacturing plant in Lincolnshire and will eventually leave the port by barge and road, destined for the main East and Greenwich sections of the Tideway project.

The main works contractor for the Tideway East project, there are separate western and central contracts for the huge scheme, is CVB, a joint venture comprising, Costain, VINCI Construction Grands Projets and Bachy Soletanche, and the train is operated on behalf of CVB by DB Cargo. Neil Grosset, Deputy Project Director CVB on Tideway East, said:

“CVB is delighted to be delivering primary precast tunnel rings into London Thamesport by rail for the East sections of the Thames Tideway Tunnel. With approximately half the rings being loaded to barges using the port’s ship to shore quay cranes for final delivery to the TBM site in Greenwich, this will enable us to provide an efficient, reliable, robust and cost effective solution whilst simultaneously delivering a significant reduction in the CO2 levels generated from the project.

“We look forward to working in partnership with the excellent London Thamesport team who have demonstrated their experience and capabilities in successfully handling similar major infrastructure and construction related projects across London and the South East. With the combined benefits of rail, barge and road connections, together with its ideal location, London Thamesport offered us a winning all-round solution which exactly meet our needs for this important project.”
