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.

September 2019 - Change of Working Hours

Works at our Heathwall Pumping Station site are progressing well, and we are now moving to the next phase of excavation on both of our on-site shafts.

Within our cofferdam we are excavating a shaft to intercept overflows from the Pumping Station. We have now dug down to 14m, lining the structure with pre-cast concrete segments. We will now change technique and construct the remaining 12m by excavating down and using sprayed concrete to line the shaft.

Our in-land combined sewage overflow (CSO) shaft has been excavated to 30m below ground and we will continue constructing this using an underpinning method, installing pre-cast segment rings to line the shaft below the existing rings that are grouted in place. Once we have excavated 2m further, we will move to sprayed concrete technique for the remainder of the CSO shaft, down to 54m.

To facilitate this new phase of works, our working hours are changing to 24hrs from Monday to Friday beginning Monday 9 September until February 2020.
