Description

The Thames Tideway Tunnel project (the Project) will control CSO discharges by intercepting and diverting combined sewage flows into a new storage and transfer tunnel. The main tunnel will run from Acton Storm Tanks in west London to Abbey Mills Pumping Station in the east, where it will connect to the Lee Tunnel, which will transfer the combined sewage to Beckton Sewage Treatment Works for treatment. The Project extends from Acton Storm Tanks in west London, to Abbey Mills Pumping Station in east London. The Project includes associated works at Beckton STW, Shad Thames Pumping Station and Bekesbourne Street.

The geographic layout of the Project and local authorities through which it passes is shown in Figure 1.
The Project comprises:
a. tunnels:
i. a main tunnel which will capture and store combined sewage from CSOs along its route and transfer it to Abbey Mills Pumping Station, from where the Lee Tunnel will transfer it for treatment at Beckton Sewage Treatment Works
ii. 11 connection tunnels, which will link flows from CSOs to the main tunnel.
b. Worksites:
i. five main tunnel Worksites (drive and/or reception sites)
ii. 16 CSO Worksites
iii. two System modification Worksites Thames Tideway Tunnel
iv. works at Beckton Sewage Treatment works.

Scope of Works

The Hammersmith Pumping Station (HAMPS) Inlet Channel forms part of the infrastructure for a live sewage pumping station. It will remain operational throughout the duration of the Main Contract works. This is a gravity-fed storm relief pumping station, with no physical or mechanical means of isolating the two sewers entering the Inlet Channel wet weather, thus all works are weather-dependent.

In order to ensure safety of the working teams, the Contractor has implemented a series of real-time catchment sewer monitoring along with computer modelling and weather forecast modelling tools which form part of the safe system of works (details can be provided on request). Within the Inlet Channel, two temporary weir walls were installed, which are interconnected with a series of flumes to divert the flows through the works area (referred to as dry zone), effectively creating a cofferdam within the sewer environment.
