Abstract
An earthquake can affect a vast category of buried lifelines performance such as water distribution system, sewage disposal system, petroleum enterprises, etc. In the present study, damage in terms of performance and working of water distribution system after severe earthquakes in a metropolitan city is assessed to develop serviceability priorities. A system simulation based on Kameda's model is also developed for obtaining useful information on the behavior of the water supply system in the pre-and post-earthquake scenario. The event modeled is the earthquake that is believed to produce extensive losses to life and property. The priorities strategy for rehabilitation of buried water distribution system is framed considering important factors such as damage in terms of leakage, reliable water demand after earthquake damage, and water distribution path length. In this study, repair management is applied systematically to restore the reliable water supply in a water distribution path. The recommendations are framed and priority of repair of the water distribution system of various paths of city zone is established such as pre-assuming a post-earthquake scenario, from the case study of one of the most important metropolitan cities of Asian country i.e., Delhi.
