Abstract: Establishment of District Metered Areas (DMAs) can significantly assist an effective and sustainable water resources management. The district of Efkarpia, located in the city of Thessaloniki, Greece, satisfies the principal DMA design criteria. The present work focuses on a detailed description of the hydraulic system of Efkarpia, a hydraulic simulation of its water distribution network investigating and analyzing different scenarios of the system's operation, combining modern geoinformatic tools (Geographic Information Systems - GIS) with hydraulic modeling techniques. In this work, a detailed mapping of the water meters of the consumers in Efkarpia district is conducted, in the frame of a DMA zoning. This GIS layer of water meters together with other features such as pumps, water tanks, and pipes, are utilized as input in a hydraulic model and hydraulic simulation is conducted. Hydraulic simulations are performed considering two basic operating scenarios, namely the operation of the old DMA of Efkarpia and of a new DMA, reduced in size, resulting from newly constructed pipes in the area. Different patterns of daily water demand, resulting from both theoretical and measured data, are used in the hydraulic simulations. The two scenarios are compared in terms of estimated pressures in the studied area, as well as in terms of energy consumption in the upstream pumping station. The comparisons reveal that the new DMA outperforms the old one, with an increase in pressure at nodes where low pressures are obtained in the old DMA, and quite significant energy savings.
