Determination of Economic Leakage Level with Optimization Algorithm in Water Distribution Systems

Abstract

It is necessary to set the most appropriate targets in water loss management (WLM) and to choose the most economically and technically suitable method to achieve these targets. The aim of this work is to define the level of economic leakage with the optimization algorithm in sustainable WLM, considering the system components, requirements and costs of the methods. For this purpose, a new model based on discrete stochastic optimization has been developed to determine the most appropriate values of the pressure level and the number of teams. After the system components were entered into the model, the optimal values of parameters were determined according to the problem-specific defined objective function. It was calculated that the pressure should be reduced from 40[Formula: see text]m to 25.30[Formula: see text]m, and the number of teams was 4 for the sample system. The Economic Leakage Level for the system was calculated as 145.85[Formula: see text]m3/day in volume and 11.9% in percentage.
