of Water Supply Systems to Landslides (PAHO, 1997)
publication focuses, for illustrative purposes, on a quantitative
vulnerability assessment of the Tuy I drinking water system that
supplies Caracas, Venezuela. The assessment applied current engineering
standards and procedures and paid special attention to the eventual
effects of seismic hazards and slope instability on the water supply
are presented on how to identify potentially unstable slopes, whether
steep or moderate, bearing in mind seismic activity and the potential
applying current engineering standards, these guidelines can assist
technicians in the quantitative assessment of the vulnerability
of water and sanitation systems to landslides.
procedures employed for estimating system component reliability
make it possible to select preventive strategies that can reduce
the risk of suspensions in service to tolerable levels.
the points stressed is the need to be systematic in compiling the
data needed - including field data - in order to develop effective
design and prevention strategies.
