Division of district metered areas (DMAs) in a part of water supply network using WaterGEMS (Bentley) software: a case study

Abstract Designing of District metered areas (DMA) schemes is a key element in developing technique for detecting and removing unreported leaks water distribution system (WDS) called active leakage control. The design DMA very specific to individual networks’ hydraulic often constitutes one area with pressure managed zones. This paper presents the division selected supply network zone into areas. Based on spatial flow rate geometrical structure (routes, pipe diameters, existing gate valves) analyzed zone, main transmission trunks were separated (DN150 ÷ DN500 diameter range) excluded from metering remaining parts network, using district module, supporting networks zones, available WaterGEMS software by Bentley. number nodes was 200 as criterion separating DMAs. combined 3 which sum lengths varied between 2500 3800 m. For each DMAs, route determined individually, seeking one-sided inflow isolated area. In two out three cases, this goal has been achieved. third case, it turned necessary provide two-sided inflow. analysis correct operation DMAs based modeling WDS.
