Evaluation of energy efficiency, energy consumption and water use efficiency in Electrical pumping stations

imum use of water and energy due to the rapid growth in water and energy demand and limitations of these resources is essential. The proper use of these resources without the knowledge of the use and efficiency of these inputs is not possible. This study aimed to evaluate the water and energy consumption, Losses and efficiency of energy for Electric pumping stations was conducted in Hamadan city farms during the 2009 to 2011. Pumping Nebraska index was applied to compare the performance of irrigation pumping stations. Also the input power, output power and total energy efficiency were calculated in pumping stations. The results showed that the total efficiency changed from 16.7 to 65.8 percent. The average of total efficiency and wasted energy of an electric pump was calculated about 49.8 percent and 8.7 KW per hour respectively. Average water use efficiency in Potato fields in the furrow and sprinkler systems was 3.1 and 6.2 kg/m3 respectively. Factors such as proper selection of pumps and engine according to the capacity and system pressure, the Proper repair and maintenance of pumps and motors can increase energy efficiency.
