Dynamic Analysis and Water Demand Model with EPANET in Drinking Water Distribution Systems

Abstract

Providing long-term water management in distribution systems is very important for sustainable network management. The basic principle in urban water management is to deliver the desired amount and quality water to the subscribers on time. In order to achieve this, the amount of water demanded in the network should be accurately defined. In demand flow, the amount of demand according to network characteristics, leakage rates, population or number of subscribers, authorized unbilled demand flow in the region should be determined accurately. In the event of a fire in the region, the flow rate required for fire intervention must be provided and sufficient pressure must be created. In order to achieve this, a model in which all components are taken into consideration should be developed in the region. Therefore, this study aimed to create and analyze the demand flow and dynamic model in a distribution system with EPANET. For this purpose, an application was carried out for the pilot isolated region in Malatya central distribution system. During the establishment of the model, necessary data, modeling stages and results obtained were detailed. In the dynamic model, demand flow rates and pressures were monitored for different time periods by making fire analysis.
