Since 1977, over seven hundred irrigation pumping plant efficiency tests have been performed by NDSU Extension. The objectives of the pump testing program are to identify the causes of low efficiency in irrigation pumping plants, determine the remedies, encourage irrigators to take corrective measures and reduce energy consumption. During the 2000-growing season, 37 pump tests were conducted for several irrigation organizations. The relative efficiencies of pumping plants for sprinkler and surface irrigation systems were compared. In general, surface systems use low-head, centrifugal pumps and sprinkler systems use deep-well turbine or submersible pumps. Due to age, improper sizing and sand pumping, 68 percent of the pumps used for surface systems had relative efficiencies below 70% while only 22 percent of the pumps used for sprinkler systems had relative efficiencies below 70%.
