Energy Efficiency and Maintenance Costs of Pumping Systems for Groundwater Extraction

Sustainability and profitability of irrigation depends to a great extent on the energy efficiency of the pumping system, as water extraction from wells accounts for most of the energy consumption in irrigation activities all over the world. In this paper a methodology is presented intended to calculate and generalize total maintenance costs in well pumping systems. Likewise, the study has been conducted over 22 well pumping stations with the aim of analyzing the energy efficiency. The results show the essential role played by preventive maintenance works in the improvement of energy and economic efficiency.
