Performance evaluation of emergency water supply system in Korea
As the importance of safety increases, constructing WSS for crisis response is also becoming important. The purpose of EWSP is to identify the exact situation of interruption when crisis happen such as a pipeline accident, and then to minimize its damage. Nevertheless, EWSP for crisis management on WSS has been analyzing the maintenance result every year with just two indicators, which are 'the Ratio of emergency water supply' and 'the Area of 100% available supply.’
As the result of case study through 10 selected indicators, although it is possible to supply water within the recovery period of, especially 24 hours, we found vulnerability exists in overall operation process. Moreover, the fact that not only the adjustment of supply interruption area but also the restriction of water and the maintenance of appropriate pressure can also have a great impact on risk situation so further research that can be reflected in the evaluation indicator group is also required.
