Geospatial hydraulic modeling and Non-Revenue Water (NRW)

Present research in order to reduce non-revenue water through cluster testing of meters was arranged in the Rasht city's water plant. In this study, rapid data intercommunication model based on Geography Information System GIS were considered in District Metering Area DMA. During the study, the consumption curve, Minimum Night Flow MNF and pressure distribution curves by water distribution network hydraulic model was investigated. The hydraulic model in compliance with GIS and WATERGEMS8.2 software in the form WATERGEMS8.2 was defined. The results of research ordered the change of 4058 meters with a negative measuring error.
