Until the 2000's, most center pivot irrigation systems had sprinklers on top of the pivot. After sprinkler technology and performance improved, and with the help of utility rebates, most pivots began use of Mid Elevation Sprinkler Application (MESA) as a strategy to reduce drift and direct evaporation. Four years ago, BPA began funding research with Washington State University (WSU) and University of Idaho (U of I) to explore how LESA could be used in the PNW. Research started with a demonstration pilot to assess the viability and suitability of the Low Energy Precision Agriculture (LEPA) and Low Elevation Sprinkler Application (LESA), (also called Low Pressure In Canopy (LPIC)) irrigation technology for broader deployment in the Northwest. LEPA and LESA technology was originally designed for center pivot irrigation in areas with short water supply, beneficial summer rainfall, and high energy costs. These measures are very popular in the Midwest and Texas. WSU and U of I focused their research on LESA, and retrofitted one span, and monitored the MESA and LESA span and found water savings of 10-15%. BPA hopes to collect data on 100 fully retrofitted LESA pivots. In January or February of 2018, BPA will have data to share with the RTF.
