The project
Capita Symonds’ Flood Risk and Water Management team were
engaged by Stroud District Council to provide ‘Land Drainage
Engineering services’ to manage remedial and improvements work to
mitigate flood risk. ‘Little Australia’ in Stonehouse was
identified as a location where improvements were a priority.
‘Little Australia’ in Stonehouse flooded in July 2007 this was
due in part to an undersized culvert passing under a railway line
becoming blocked and subsequently causing water to back up and
flood homes.
Capita Symonds proposed different engineering solutions to solve
the undersized culvert and the blocking up of the culvert.
The option chosen by the client was to improve the inlet and
screen.
Our team managed the design, fabrication and installation of a
new screen that would be less prone to backing up, easy and safe to
operate and reduce the risk of flooding to residents living in
‘Little Australia’. The key features of the new screen and
channel include:
- Wingwall realigned to improve the flow of water into the
culvert
- Angled metal spikes removed from the channel bed
- Channel width upstream of the screen straightened.
- Galvanised mesh standing and lockable access provision above
the screen.
- Wider screen to match the width of the channel and
incorporation of side panels
Capita Symonds transferred the operation and future maintenance
of the screen to Stonehouse Town Council.
The design fabrication and installation was managed by Capita
Symonds using Environment Agency approved contractors. The
fabrication and installation process took two months to
complete.
