Leakage of water from water-carrying services can be a serious risk to the stability of slopes and retaining walls even at some distance away, as in the case of the fatal Kwun Lung Lau Landslide of 23 July 1994 (GEO, 1994).

WSD carry out systematic leak detection procedures in our daily works, this guideline serves as a document introducing the common practice in leak detection that maintenance agents can make reference to and follow. To pinpoint suspected leak spots, some
Persistent leakage of water from buried services not only causes nuisance, but can also be a serious risk to the stability of slopes and retaining walls. Water-carrying services including stormwater drains, sewers, water mains, catchwater channels and water tunnels are prone to leak.
history of leakage (preliminary information on water pipe leakage is available on the Slope Information System at web-site http://geosis.ccgo.hksarg), etc., should be obtained.
Geosynthetic leachate collection systems have been used widely since the mid 1990s. They have largely replaced conventional gravel drainage layers on landfill side slopes and there are many advantages of using these systems.
The basic function and importance of leachate collection and removal systems are first presented in Chap. 2, but Chap. 10 significantly expands this introduction and provides a discussion of the major design and operation considerations of LCRS in the context of sustainable landfilling.
This report presents the findings of an overall review of selected notable incidents involving slopes affected by leakage of water-carrying services. Areas that warrant attention are identified and follow-up actions are recommended.
LSC6Leakage collection reservoir. The EagleBurgmann leakage control systems of the LSC6000A4 range are utilized to collect condensing or mixed phase leakage - vapor passing through. A level indicator is installed to determine when the tank needs to be drained. A pressure gauge tracks and indicates seal leakage.
