The Thames Tideway Tunnel is a major new sewer, urgently needed to protect the tidal River Thames from increasing pollution caused by combined sewer overflows (CSOs) discharging sewage into the river. At 25km in length, up to 7.2m in diameter and 65m underground at its deepest point, the tunnel will be the largest project of its type in Europe. Starting in west London, the proposed route for the main tunnel generally follows the route of the River Thames to Limehouse, where it then continues north-east to Abbey Mills Pumping Station near Stratford. There it will be connected to the Lee Tunnel, which will transfer the sewage to Beckton sewage treatment works.

The project requires a total of 24 sites across 14 London boroughs to construct and operate it. Once operational the tunnel (in conjunction with the Lee Tunnel) will reduce discharge volumes by approximately 94% in a typical year. The project is well into construction with over 50% of the tunnelling completed. A presentation will be given looking at the history of the project, the engineering and construction challenges encountered during delivery.

Refreshments will be available from 18.00 and the talk will start at 18.30.
