Piling secures substation from flooding risk

Flood protection for a National Grid substation in Gloucestershire that will prevent future network disruption is being fast tracked by Trant through use of specially acquired equipment.

Trant is using a new 26t JCB JS260 excavator with a computer-controlled Movax piling attachment to install a sheet piled cut off wall around the substation at Walham which became an icon of the summer 2007 flooding.

The substation site, which is located in the flood plain of the River Severn, was saved by the worst effects of the flooding and electricity to the 500,000 people was maintained by swift action to surround it with sandbags.

Work on the 1km long sheet pile wall is due to be completed this summer but progress has not been straightforward as heavy rain during the 13 month contract period has meant that Trant has had to contend with flooding on site.
