The Revenue Water(RW) rate, used for a performance assessment and a performance improvement in Korea, was calculated through top-down analysis. However, Some problems that RW rate lack credibility have been pointed out as a performance indicator. Therefore, the relationship among the RW rate, Non-Revenue Water(NRW) and the system input volume were analyzed. The results of this study showed that the RW rate varied with system input volume even if the NRW has a certain value. Furthermore, the relationship between the RW rate and real loss, using performance improvement, could not be identified. Based from the results of this study, the necessity on the application of a new performance indicator was confirmed. Moreover, the Infrastructure Leakage Index (ILI), RW rate and NRW rate were analyzed in this study. It was observed that there was a high correlation between the ILI and real loss(R2=0.9185), and NRW(R2=0.8069) represents the condition of the water supply system. Therefore, ILI was chosen as performance assessment indicator to represent the exact water loss in the water supply system. KCI Citation Count: 0
