This committee report, Seismic Loss Estimates for a Hypothetical Water System demonstrates how earthquake loss estimates can be developed for a water system. As the October 17, 1989 Loma Prieta, California earthquake has reminded us, effects of natural disasters on the infrastructure can be devastating. The type of seismic risk analysis performed in this demonstration project is designed to encourage the control of these effects through prudent management and engineering, and through governmental and private industry practices that encourage loss-reduction activities. First, a hypothetical system was defined, with components representative of those in actual systems. Replacement cost estimation procedures were applied to these components. A realistic setting was provided, with earthquake faults, contours of depth to basement rock and high liquefaction susceptibility zones. Strong ground motion attenuation functions were defined. Earthquake loss models were then provided for all the components developed and relative to local hazards of strong ground motion and liquefaction-induced ground failure. Finally, types of earthquake loss estimates were developed that can assist in water system risk reduction and capital expenditure planning programs.
