Abstract
Recently International Water Association(IWA) has proposed new performance indicators for water supply services and their successful applications are being reported continually. According to the various reports, the percentage indicators were suggested not to be used for performance comparison, especially where the targeted areas have great difference in consumption per service connection. But unfortunately in Korea the revenue water ratio, one of the percentage indicators is still being used to set up the goal of water-related administration and to compare the performances between systems. Therefore this study aimed to prove the inapplicability of the percentage indicators with nation-wide data and to suggest better performance indicators for more efficient water loss management. According to the result of the comparison of various performance indicators with conventional one, it is roved that percentage indicators ca not evaluate the performance efficiently where the local situations are significantly different. It is suggested that the better performance indicators such as real losses per service connection or ILI should be used to benchmark the performances of water suppliers on water loss management so thai the problems of water losses could be identified easily and recovered effectively.
