Project Overview:
Flooding and a sink hole appeared within a Parish Council Recreational Playground. CCTV work was
carried out and a collapsed sewer was found to be at fault.
Description of Works:
YW appointed TSL to dig and repair the collapsed sewer, as the repair was made further collapses
appeared along the sewer pipeline. Trenchless Solutions carried out further investigation and due
to the ground conditions being running sand, with a high-water table and environmental issues
with mature tree canopies above the existing pipeline, TSL proposed an off line replacement of
DN225 Denlok VC foul sewer by GAB.
