Practical Solutions

  • Seal the footing of hoarding to avoid seepage of surface run-off out of construction site
  • Install wheel washing facilities including a high pressure water jet at each site exit to avoid carrying of dust and soil to public road by site vehicles
  • Construct perimeter temporary drainage channel and catchpits along the site boundary to intercept surface run-off from flowing out of construction site. The temporary drainage system should be suitably maintained with the deposited silt and grit being removed regularly to ensure the system could direct the surface run-off to wastewater treatment facilities at all times
