Abstract. The article shows the importance of the problem of improving efficiency of energy use in technical and technological systems. One of the ways of improving energy efficiency of water supply systems is the use of new energy-efficient technologies and pumping equipment, the use of modern management systems. Modern trends in the evaluation of energy consumption for operation of pumping equipment of water supply systems were analyzed. New methods of improving energy efficiency of pumping units in water supply system, taking into account the real operating conditions, were presented.
Key words: energy efficiency, pumping unit, pressure, flow, regulation, working field, the target value, the index of efficiency.
