Case Studies
Culvert 34 Whitchurch Canal Breach Site
Culvert Cleaning & CCTV Survey | Kier NR&N
Method of Works
Culvert Clean & CCTV
~50m of 1200mm x 1200mm brick culvert cleaned and surveyed to full WRc standard
Downstream Twin Pipes
~33m of twin 225mm clay pipes cleaned and CCTV completed (Stage 2)
100% Silt Removal
All pipes 100% full of debris due to the breach – finished silt levels reduced to less than 10%
Portable Equipment Deployed
Material stockpiled at End B and loaded into 20-tonne haulage lorries for disposal.
Key Challenges & Highlights
Difficult Access
Inlet side became a sand pit from the canal breach. Outlet accessed via active plant track across wet farmland, requiring full portable setup.
Live Site Co-ordination
Works ran in tandem with ongoing major earthmoving operations, requiring continuous programme co-ordination to keep both scopes on track.
Technical Complexity
Culvert location and 100% silt blockage required multiple equipment configurations and expert planning to safely clean and survey.
Project Summary
Delivered On Time. On Budget. To Specification
Culvert cleaned, CCTV completed, and drainage restored – allowing water to drain naturally off the field and the watercourse to function as intended.
