Analysis of Technical Indicators for Leak Performance in District Metered Areas with Active Leak Control

Abstract

Active leak control method is applied to detect and prevent unreported leaks in distribution systems. However, during the application of this method, the field works are carried out in the field and cost is incurred. For this reason, it is necessary to analyze the benefits obtained after applying this method. This benefit is basically the amount of leakage prevented by the application of this method. In this study, active leakage control was applied in isolated measurement zones in drinking water distribution systems and the gains were analyzed according to technical performance indicators. In the application area, active leakage control has been applied in 4 isolated measurement zones. The total volume of leakage prevented at the beginning and end of the study was determined. Then, technical performance indicators were calculated for each isolated measurement zone. These indicators are basically leakage amount per unit network length, leakage amount per unit service connection. With the help of these indicators, it provides an opportunity to evaluate whether the active leakage control implemented improves the leakage performance of the system or not. It is thought that the outputs obtained from this study will make important contributions especially for practitioners.
