The 25 km long Thames Tideway Tunnel, with an internal diameter of 7.2 m, is a large wastewater interceptor and storage tunnel designed to prevent several million cubic metres of untreated wastewater from spilling into the Thames each year. Access to the tunnel, which is driven at depths of between 30 and 60 metres, is via deep shafts and access tunnels. For the access shaft on the Victoria Embankment construction site, the AT – Pipe Umbrella System with innovative squeezed connection was used to secure an access tunnel at the base of the shaft (see page 665).
