In our application for development consent this site intercepts the Heathwall Pumping Station combined sewer overflow (CSO) and the South West Storm Relief CSO.
Heathwall Pumping Station is an existing Thames Water pumping station site. The proposed site includes the existing pumping station and Middle Wharf, owned by Thames Water. The surrounding area is predominantly industrial and mixed-use, but is becoming more residential. The location of the site is shown below.
Construction is assumed to start in 2017 and be complete by 2020. Where appropriate some advance works may be carried out before the main construction period.
Work includes construction of underground structures to connect the CSO to a shaft approximately 46 metres deep with an internal diameter of approximately 16 metres. This shaft would be constructed at Middle Wharf, and would Transfer sewage flows from the CSO to the main tunnel.
While most of the operational structures would be underground several ventilation columns would be permanent above ground features, but located within the existing pumping station compound.
Please refer to the application documentation on the Planning Inspectorate’s website (link below) for full details of our proposals for this site.
