The paper presents a method of evaluation of energy efficiency in the upgraded water supply on the basis of electrical modeling of electromechanical system as a part of electrical industry. Q?H characteristics of electromechanical systems were zoned to determine the boundaries of energy efficient operation, given the volumes and the possible ways of modernization and the impact of losses in electric drive motor. The authors calculated and built within the fields of electromechanical systems Q?H characteristics of the pump unit type DR field changes, the unit cost of electricity was used to determine the estimates of the energy efficiency of EMC for predetermined parameters of the hydraulic network. It is proved that the most appropriate integral criterion of energy efficiency of hydraulic water supply is a measure of unit cost of electricity for pumping unit volume of fluid. Obtaining the necessary input data for its calculation does not require additional tools other than driven electric meters consumed electric energy meters pumped liquid and pressure gauges, which are usually equipped with water supply. Using this indicator in the calculation of the value of the life cycle of the hydraulic water supply allows to compare possible options for upgrading equipment and network elements in order to improve their energy efficiency.
