Modeling of Water Distribution System Based on Ten-Minute Accuracy Remote Smart Demand Meters

In the process of water distribution system modeling, nodal demands have been deemed to be most significant input parameters causing uncertainties. Conventionally, users same type are assigned demand pattern, which does not reflect variability in patterns. Hefei City, a lot remote smart meters were installed recent years, providing real-time consumption data for different user sites. this study, based on 10 min accuracy collected and used established EPANET model study area. A 48 h simulation, including workdays weekends, was carried out, each node’s base pattern accurately calculated according data. The results show that has met modeling criteria (less than 2 m all pressure monitoring points), there is no need calibrate demand. offline hydraulic can better characteristics revealed influence secondary supply systems.
