Water supply systems have a significant environmental and energetic impact due to the large amount of energy consumed in water pumping and water losses. The safe and efficient operation of these systems is crucial, given the scarcity of resources and the high amount of energy consumed in water transporting to the final consumer. In this work, operational and hydro-energetic indicators of an urban water supply system (pumping station) were analyzed. The energy efficiency of this system was studied with data availability restrictions. The methodology was applied in part to the water supply system located in the State of Paraíba, Brazil (city of Guarabira). The available data were obtained from the supervisory system (SCADA) of the State Water and Sewerage Company. Energy efficiency analysis – in different dynamic operating scenarios – was performed using a high station hydraulic model obtained from the EPANET software. The increased efficiency of the pump set studied is quite attractive due to the energy savings associated with the pumping process (reaching more than 50%). The pump shutdown maneuver at peak times proved to be unfeasible for the current system settings.
