10.3.1 A proper drainage system will be provided at the fill bank and at the Construction and Demolition Material Sorting Facilit to collect surface run-off. The drainage system will incorporate silt traps and oil traps at appropriate locations to remove sand, silt and oil carried by the surface run-off. These traps will be frequently cleaned and maintained. As a wheel-washing facility will be provided near the exit to wash the wheels of the trucks before they are leaving the site, muddy water from the wheel-washing facility will be treated prior to discharge. The effluent arising from the site will be treated to the required standard of the Water Pollution Control Ordinance and will be discharged into the existing drainage system under a licensing control of the Director of Environmental Protection.
