A technique of the optimal selection of power units and their operation mode in the booster pumping station of the water supply system with a reserve tank is proposed. The optimization mathematical model of pumping station in the form of a non-linear, multi-criteria, partially integral mathematical programming problem is developed. Necessary data for optimization problem definition: the structure of daily water consumption by consumers and resistance of the water-supply system were found on the base of a full-scale experiment results. The adopted approach has provided both mathematical rigor of the problem formulation and solution, and real data recording of consumer behavior and water supply system conditions. The processing of the full-scale experiment data was carried out by statistical methods of analysis of non-stationary random processes. The optimization procedure was realized with the help of genetic algorithm method. Comparison of booster pumping station operation optimal plans on the base of different centrifugal pumps has allowed choosing such a type of pump, that when using it, maximum energy efficiency of the water supply system is achieved and operation of pumping station with minimum number of pumps with maximum possible efficiency is provided. Minimum essential dimensions of a reserve tank, optimal operation speed of the centrifugal pumps are determined.
