Slope StabilisationWork in Shatin The project involved a major slope stabilization works at Lai Ping Road, Kau To, Shatin.

Environmental Concern Muddy wastewater generated from the construction activities was of major concern. Substandard wastewater if discharged would lead to the Tolo Harbour via the Kau To Hang and adversely affected the water quality of both the river & the harbour.

Extensive site coverage of the slope stabilization project at Kau To

Measures Adopted Treatment - Wastewater generated from the construction works would be pumped to a sophisticated wastewater treatment system for removal of the suspended solids, before discharging to the nearby streams and the harbour.

Installation of WepSep Wastewater Filtration System at about $200,000 for effluent quality control
