Developing an Optimization Algorithm to form District Metered Areas in a Water Distribution System

Exploiting the numerous possibilities that unfold from the inter-connection of Matlab and Epanet software, an algorithm is produced in C++ language. The algorithm reads all the significant data of the water distribution network from Epanet. Matlab calculates the optimized isolation valves allocation in terms of water losses reduction, considering vital limitations for the well-functioning of the network. The algorithm can be implemented in all water distribution networks. The outcome is a hierarchical list of closed pipes, causing the higher reduction in network's operating pressure. The closing of the pipes (or the installation of isolation valves) determines the optimal segmentation of the network in District Metered Areas. The process for the formation of the algorithm and a case study on a network' hydraulic model are presented.
