The groundwater level is declining day by dy and remains under 30 ft. in most of the places in the Barind tract of Bangladesh throughout the year, therefore it is mandatory to use submersible pumps in that location. In this work, the energy consumption behavior and life cycle cost elements of submersible pumping system have been studied in different areas of Rajshahi division. It is found that the efficiency of the running pumps is reduced by 20-40% more than that of lab test results of the new pumps. Moreover, it has been found that the energy consumption cost of the submersible pump is almost 64% of the total life cycle cost. In the present work, the performance of a 15 HP submersible pumping system has also been studied at the laboratory scale by varying bore well diameter. It has been found that the submersible pump shows a maximum effic8-inch in 8-inch bore well (51 %) than that of 10-inch (49%) and 12-inch bore well (48%). It has been observed that the drawdown increases and efficiency decrease significantly with increasing bore well diameter. [ABSTRACT FROM AUTHOR]
