Abstract

This report presents the findings of an overall review of selected notable incidents involving slopes affected by leakage of water-carrying services. An overall review of the recent notable incidents involving slopes affected by leakage of water-carrying services re-affirms the importance of paying due attention to the corresponding potential slope hazards, as leakage has affected not only non-engineered man-made slopes but also engineered man-made slopes and natural hillsides. The findings indicate that the key problems are generally associated with ageing pipes, inadequate investigation of the adjacent water-carrying services during the design stage of the slope upgrading works, together with inadequate attention to detailing. Areas that warrant attention are identified and follow-up actions are recommended.
