Derbyshire County Council employed Land & Water Services to carry out dredging works on the Cromford canal to improve the ecology and habitat of the waterway. The site was registered as a SSSI which required close liaison with Environment and Regulatory bodies. The main challenge was to ensure the integrity of the SSSI site was maintained giving due regard to wildlife, Fauna and Flora and general ecology of the site and surrounding areas.
Mobilisation including access and egress to the site compound which were made difficult due to the adjacent railway tunnel and line which required careful planning and consideration. Access to the waterway was further hampered by the location of a restricted weight bridge at the entrance to the site. A 13 ton excavator was fitted with an extended turret to raise it above water level allowing the machine to track up and down the waterway to load awaiting hoppers.
The works were split into two phases to accommodate the location of an uncharted sewage pipe which was found within the working area. Arising’s were spread to land requiring exemptions and prior liaison with the local Land owner. The field utilised was sectioned and tiered to allow material to be placed, dried and spread to agreed tolerances. Our Client Derbyshire County Council were extremely pleased with the out come of the project.
