N2 - To use the revenue water ratio and standardized leakage volume indicators as an output factor, this study developed a model that can analyze and evaluate the efficiency of four investment costs (expansion, renewal, labor, maintenance) for the maintenance of water supply facilities, utilizing data envelopment analysis. And this study would prepare measures for the implementation of the optimal maintenance efficiency by setting the priorities for investment, considering the efficiency of the investment using multiple regression analysis. Currently, the Korean Government is carrying out a waterworks modernization project for the improvement of deteriorated water utilities to convert the vicious circle of water supply service to a virtuous cycle. It is concluded that the efficiency assessment index and utilization methodology for investment costs for the maintenance proposed in this study can be reflected in the promotion of the relevant project. In addition, it is concluded that this study can be utilized to promote the efficiency of investment in the maintenance of water utilities.
