Heathwall Pumping Station

Site information

Thames Water and Tideway have completed works to upgrade the existing water and gas mains under Nine Elms Lane. This work was vital to prepare the essential utilities for our main works construction in the coming months. We have begun our main works construction at Heathwall pumping station. We will soon begin works such as site clearance, sewer outfall diversions, investigative boreholes and preparation for the construction of the main shaft.

Heathwall Pumping Station

May 2020

Following a pause to our works as part of our response to the COVID-19 outbreak, we have resumed some work at our Heathwall Pumping Station site. We have introduced several additional precautions so that our team can do this work safely.

We have constructed two deep shaft structures which will drop intercepted sewage and redirect it towards the new super sewer.

The smaller of the two shafts was built within a cofferdam, a dry working area built out into the river. This shaft is 28m deep and will intercept the sewage from the Pumping Station. From the bottom of this shaft, we have excavated across to build a 42m-long tunnel that will connect to the deeper on-site shaft and are now preparing to cast the secondary lining of this tunnel.

Our deeper shaft reaches a depth of 47m below ground. From the bottom of this structure, we are constructing a tunnel portal, to allow us to begin construction of a tunnel that will connect the shaft to the main super sewer tunnel being constructed below the River Thames.

All non-essential staff who can work from home are doing so.
