The study focuses on saving energy in the process of drinking water distribution in the rural area. The hydraulic model of the water distribution network that supplies Dulcesti village, Constanta County, Romania, developed in EPANET is the basis to performing a thorough analyse of the hydraulic system’s operation. The standard hourly water demand is taken into account. The network is a branched one, widen on a large area so that the ratio is about 10m of pipe per inhabitant. The difference in junction elevation is up to 37m and furthermore there are big differences of elevation between junctions placed close one to each other. These features of the network impose the analysis of pressure field in various scenarios of pumping methods. Different alternatives for the network configuration (branched and looped network) are considered in order to meet the required technical parameters. Numerical simulation pointed out the optimal pumping alternative, by using variable speed pumps. The subsequent energy saving is 35% comparing with the actual consumption.

Keywords: water distribution network, energy consumption, variable speed pump.
