The most common method of irrigation in the Pacific Northwest is sprinkler irrigation (73% of irrigated acres), and by far the most popular sprinkler irrigation method is the center pivot (62% of sprinkler acres).  Improvements to the irrigation application efficiency of the center pivots has a large effect on water and energy use, which of course are related.  Using low pressure irrigation with discharges right down by the ground and more closely spaced reduces water use and pressure, so pumping energy drops considerably.  I was wondering if some utilities have customers who have experimented with this approach and have documented results of the savings, or of expected or unexpected results, welcome or otherwise.
