ABSTRACT

This study aimed at determining Infrastructure Leakage Index (ILI) supported by Geographic Information System (GIS) to facilitate strategy determination, map problems, and determine potential revenue for actions to solve leakage realistically, effectively and efficiently. Economic analysis was carried out to determine investment feasibility of corrective actions for leakage of clean water network infrastructure. More importantly, variables in this study were obtained from literature review. Primary and secondary data were then collected and analyzed statistically, and other economic analysis tools were also used. This study used a quantitative method with a population of 11 (eleven) service zones involving 35 leaders, executors and staff of leakage team. All populations of service zone were taken as research sample, while for leakage team, sample was taken using Slovin formula which obtained 32 respondents. Questionnaires were distributed to find the main affecting factors using AHP (Analytical Hierarchy Process) method with the help of Expert Choice software Results of this study indicated that there were basically five main factors causing water loss due to infrastructure leakage. Handling infrastructure leakage could reduce rate of physical water leakage by 48.5% (from 11.38% to 5.86%) of the total physical losses per year. In addition, return on investment was obtained in year 3, while profits were earned in year 4.
