EndSafe and EdgeSafe panels for reception pits (2017)

EndSafe and EdgeSafe panels for reception pits

The village of Fenny Bentley is situated near Ashbourne in Derbyshire. Severn Trent Water awarded a contract to NMCNomenca (now nmcn PLC) to construct a new sewage pumping station in the village to replace the existing pumping station which has reached the end of its working life. At the same time, the existing Fenny Bentley Sewage Treatment Works, which is also life-expired, will be demolished and the new pumping station will divert flows 4km via a new sewer to Severn Trent’s Ashbourne STW. Groundforce Shorco has supplied a full complement of trench support equipment, including ladders and ancillary components to the contractors.

New sewer/rising main

As part of the project, NMCNomenca (now nmcn PLC) is installing the new sewer which comprises a 125mm diameter rising main. This 1km pipeline feeds into an existing gravity sewer to Ashbourne.
To accommodate fluctuations in both sewage flows and surface-water run-off, NMCNomenca is installing a storage pipe, comprising 350m of 1,050mm diameter concrete pipe, in-line with the existing sewer.
The small-diameter rising main has been installed using trenchless techniques by specialist JMH Directional Drilling. Each run is between 100-150m and JMH need a launch pit from which to drill and a reception pit at the other end so they can pull the new pipe through.
Groundforce Shorco supplied its Backhoe Trench Boxes, Endsafe panels and access ladders to support the sides and ends of these 2.0m x 2.5m x 2.5m deep pits and ensure safe working.

Concrete storage pipe

Downstream, where subcontractor Clumber Construction is installing the concrete storage pipe, Groundforce has supplied its Standard Trench Boxes, 3.5m Manhole Boxes and Pipe-Lifter.
Groundforce Shorco Technical Sales Representative Darren Boote explains that whilst this a fairly standard job, using standard equipment, Groundforce are one of the few companies that can meet the requirements of a client like NMCNomenca having the necessary range of equipment and its availability.
“Groundforce are one of NMC Nomenca’s preferred suppliers because they know we can respond quickly and with the ideal solution,” adds Darren.
Work began on the pipeline in October 2016 and completed in May 2017
