Document Type: Proceeding Paper

Part of: Recent Lifeline Seismic Risk Studies


This year a monograph is being produced that summarizes results of a four-year project by the Technical Council on Lifeline Earthquake Engineering (TCLEE) of ASCE in order to demonstrate how earthquake loss estimates can be derived for a water system. This paper provides a brief synopsis of this project performed by the Water and Sewage Committee and the Seismic Risk Committee. The project focused on estimating losses as a percent of replacement cost. Explained are two of the key difficulties encountered in estimating seismic losses for water systems: the absence of a uniform inventory method and the absence for some key water facilities of sufficient earthquake damage data. Discussed are some of the ways in which inventory methods are being improved.
