The prospects of improving the energy efficiency of boosting pumping stations


«Samarskie kommunal’nye sistemy» LLC has been providing cold water supply, wastewater collection and treatment on the territory of the Samara urban district. One of the main tasks of the enterprise is improving the energy efficiency of boosting pumping stations. For this purpose a comprehensive approach to the selection of the number and trademark of pumping units as well as to the practicability of installing variable-speed drives is required. In contrast to the projected pumping stations with calculating the duty cycle of the pumps, with the existing stations solving the problem of minimi­zing wasteful energy losses requires studying the established water consumption pattern; determining the required pressure at the pumping station outlet and available pressure in the municipal distribution network. The problem of maintaining optimal pressure at the boosting pumping station outlet shall be considered: constant maximum design pressure; changed as per schedule; depending on the flow rate. Arranging a complete water audit, identifying illegal water consumers and optimizing the operation of block pumping stations with the use of variable-speed drives will provide for the significant reduction of water and energy consumption. The comparison of the dynamics and specific water consumption in separate residential buildings with the operation of the block boosting stations supplying water to separate residential buildings and blocks and with the existing regulation is presented. The diagrams of the specific water consumption patterns and variations in water consumption within 24 hours are given. The conclusions related to the prospects of improving the energy efficiency of the boosting pumping stations operated by «Samarskie kommunal’nye sistemy» LLC are drawn.
