Review of incidents involving slopes affected by leakage of water-carrying services

The potential adverse effects of leakage on slope stability in Hong Kong were highlighted by the Mid-levels Study and reinforced by the 1994 Kwun Lung Lau landslide, which resulted in five fatalities and three serious injuries. The systematic landslide investigation programme introduced by the Geotechnical Engineering Office (GEO) in 1997 has further identified a number of notable incidents involving slopes affected by leakage (or bursting) of buried water-carrying services. To enhance the current practice and contribute to reducing the risk of slope failures caused by leakage from water-carrying services, an overall review of relevant incidents in recent years has been carried out in order to identify areas that warrant attention and improvement. This report presents the findings of the review and suggests some recommended follow-up actions.
