COST-BENEFIT ANALYSIS OF PRESSURE MANAGEMENT PRACTICES IN DRINKING WATER SYSTEMS

Combating losses in drinking water has become one of the most essential freedoms today. With increasing water problems, the decreasing clean water resources have increased the fight against water losses in drinking water systems. In international literature, pressure management is the most important method of fighting against water loss. In this study, pressure management was applied in 4 different isolated sub-regions within the scope of water loss management. The isolated sub-regions under pressure management were selected from the networks operated by the Kayseri Water and Wastewater Administration (KASKİ) with different pressure regulation methods. The financial benefits of pressure regulation were theoretically calculated using algorithms. The algorithm's accuracy was tested by comparing the accuracy of the theoretical calculations with the actual field practice results. After analyzing the accuracy of the theoretical calculation, the costs were also calculated, and the return period of the investment was calculated by making a benefit and cost analysis.
