In our application for development consent this site connects the existing local combined sewer overflow (CSO), known as Frogmore Storm Relief–Buckhold Road CSO, to the main tunnel via a long connection tunnel, known as the Frogmore connection tunnel.
The King George’s Park site encompasses a small part of the northern end of King George’s Park adjacent to the entrance from Buckhold Road and the junction of Buckhold Road and Neville Gill Close. The location of the site is shown below.
Construction is assumed to start in 2017 and be completed by 2019. 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 21 metres deep with an internal diameter of approximately nine metres. This shaft would be built in the northern part of King George’s Park, and would transfer flows from the CSO to the connection tunnel and then onto the main tunnel.
While most of the operational structures would be underground, ventilation structures and an electrical and control kiosk would be permanent above ground features.
