In recent years, due to the country's energy conservation policies in cities and towns, there has been a steady decline in the specific water consumption. Many industrial enterprises switched to water-saving technologies and circulating water supply systems. Such a policy favorably affects the environmental safety of territories by reducing wastewater discharges into water bodies and saves energy for pumping water and wastewater. At the same time, due to a decrease in the speed of water movement, its quality indicators deteriorate and stagnant zones appear, and due to the reduction of water consumption, pumping stations began to operate in low efficiency modes. The article proposes to solve this problem by decommissioning certain sections of the network and facilities, which improve the speed of other pipelines and provide pumping stations with the highest efficiency. For this purpose, a technique has been developed to optimize flows in existing water supply systems and its implementation in the Trace – BK software package. A new method of optimizing operating costs for water supply systems in the face of decreasing water consumption is proposed. This technique makes it possible to identify inefficient sections of network and take them out of operation while improving the operation speed of other pipeline and bring the operation of pumping stations to the mode with the highest efficiency.
