Investigation of optimizing strategies for energy consumption at drinking water pumping stations in the central part of Khorramabad city in 2017

This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacitor on energy consumption, electricity need, re-engineering the electro-pumps and determine the volume of the required reservoirs were the survived parameters. The results showed that the installation of capacitors in the selected stations saved 14.9 percent of electricity consumption. Pump shutdown during peak hours will also reduce electricity consumption costs by 22%, and from the 10 selected pump stations, 4 stations will need to be re-engineered, and their replacement will optimize efficiency and saved 14.47% power requirement. Also, the reduction in electricity demanded in 4 stations out of ten stations will save 14.77% of energy consumption. Simultaneous application of capacitors installation, pump shutdown, pump station re-engineering and demand reduction we will save a total 46 % energy consumption. According to the obtained results, organizations and related companies can use these results to optimize energy consumption and pumping costs.
