The main goal of this study is evaluation of reconstruction options for water pumping stations, regarding various factors (equipment purchase cost, maintenance, energy consumption). The search for the most profitable solution was carried out using the life cycle cost methodology for the urban water supply system’s first lift pump station. An analysis of the operating modes of the pumping station was carried out using curves of pumps and system. It was found that the option with a higher purchase price has the best technological indicators, including energy consumption. The expediency of the complete replacement of pumping equipment is confirmed by an analysis of life cycle costs.
