Decomposing Water Distribution System into District Metered Areas for Leakage and Water Age Reduction

摘要

This paper proposes a multi-objective model for the design of a water distribution system (WDS) with numerous elements including pipes, valves, pumps, and storage tanks. The main focus of our decomposition of a WDS to district metered areas is on decreasing water leakage in the system without corrupting the customer service. In other words, the customer demand is to be satisfied and meanwhile the operating pressure and water age will be minimized. The advantages of the proposed model are illustrated through case studies.
