Location & Overview

As part of the Thames Tideway Tunnel project, Hammersmith Pumping Station is an existing Thames Water site in a residential part of west London. The overall works were to enable the ‘interception’ of the sewage overflows from this site, reducing discharges by more than 95% and playing a key role in cleaning up the River Thames.

Work, Challenges & Solutions

John F Hunt was appointed by Thames Tideway Central to remove the 14m long, 5.5m high and 2.5m wide central directional wall within the live inlet chamber.
Working to a height of 5.5m, we used diamond drilling rigs to create holes for wire feeding preparation and lifting. The concrete was then cut into 3 tonne sections with a diamond wire saw, which were lifted out and processed.
Operating within the live inlet chamber under strict permit conditions, within a CP2 confined space using innovative wire sawing and lifting techniques. Heavy rainfall meant frequent evacuation from the chamber owing to potential flooding.
