A S & D Drainage Services Case Studies of Somerset County Council

Project Info:

  • Completed on: 27 February 2015
  • Client: Somerset County Council
  • Location: Bridgwater

Multiple problems were being experienced around the school due to tree roots. A full CCTV survey revealed the extent of the infestation and it was agreed that CIPP lining after root cutting would be the least disruptive option. What we did not expect was the severity or strength of the growth. The pictures above show a single section of matted root 150mm diameter and 6mtr long that was removed by excavation to the main poin t of ingress, tying a rope round the exposed root and dragging it out in a single piece. This was not the only heavy infestation. The picture to the left shows an engineer holding up a single root removed from another drain and no before you ask, he is not very small, he is well over six foot tall! Some root! Once all the root had been removed from the drains, heat cure Epoxy resin CIPP liners were installed in long runs and Polyurethane resin liners in short sections. These will prevent further intrusion and save having to excavate and replace the entire system
