In our application for development consent this site receives the main tunnel from Carnwath Road Riverside. It also intercepts the existing Acton Storm Relief combined sewer overflow (CSO).

Acton Storm Tanks is an existing Thames Water pumping station and storm water tanks site. The surrounding area is predominantly residential, industrial and mixed-use. The location of the site is shown below.

Construction is assumed to start in 2018 and be complete by 2021. 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 31 metres deep and with an internal diameter of approximately 15 metres. This shaft would be constructed towards the northern end of the site within two of the existing storm tanks, and would transfer sewage flows from the CSO to the main tunnel.

While most of the operational structures would be underground, a ventilation column and other smaller structures would be permanent above ground features.
