Potential Conservation Opportunities from the Use of Low-Pressure Irrigation in the Pacific Northwest Region

摘要

Four types of low-pressure irrigation technologies were examined in reference to their energy-savings potential and their costs per kWh of savings. Various conversion alternatives were selected for analysis from among the technologies of low-pressure single spray systems, low-pressure spray booms, furrow drop-tubes, and low-pressure impact sprinklers. A summary of the conversion alternatives that were analyzed and the major results for each alternative is presented. The energy-savings input parameters selected for use in this analysis were generally in the low range of available estimates and the cost input parameters were generally in the high range of available estimates.
