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

In order to create an area of land in the river to work from, we have created a watertight 'cofferdam' - the edging of which is now complete. To build a cofferdam we first had to install 'piles' in the river. These are thin, interlocking, metal sheets that we drive into the riverbed, one by one until the perimeter is sealed. We then drained the water from the new enclosed area.

We needed 41 'piles' to do this and the piles were up to 25m in length. The cofferdam structure now provides a dry working area for the team on the river. This will be the base for the new embankment, a new permanent area of land that will be created for public use following the completion of the project. 

March 2019 - New Pedestrian Crossing

We previously contacted you regarding the changes to traffic management on Nine Elms Lane, outside of the Heathwall Pumping Station worksite. The changes are to facilitate the Tideway works whilst ensuring minimal impact to the local community and road users. This is to update you on those works.
