Efficient Irrigation

    Table of contents


    Facilities meeting one or more of the following criteria may benefit from this opportunity.

    • Multiple pumps run in parrallel
    • Pumps are not checked for impeller wear or damge annually
    • End use requirments vary significantly from day to day



    In any irrigation system, opportunities for reduced operating cost arise out of:

    • Lowering required water horsepower by:
      • Reducing pumping outlet pressure by minimizing distribution line pressure losses, and end of line pressure requirements.
      • Reducing the volume of water pumped by ensuring excess water is not delivered to any end points, or bypassed to source without being used.
    • Increasing pump efficiency. The efficiency of any particular pump is a function of:
      • Operating point on its flow versus head curve: pumps have one Best Efficiency Point (BEP) and efficiency deteriorates as the point of operation moves away from this point.
      • Pump wear: as a pump ages, both impeller and housing wear and pump performance and efficiency deteriorates.
      • Pump design: Pump efficiency can be improved by
        • Ensuring it operates as close as possible to its best efficiency point
        • Overhauling it
        • Replacing it with a better selected pump



    These templates are excel based spreadsheets that quickly and easily help users quantify energy savings, cost savings, implementation costs, and payback.  The excel spreadsheets then automatically write a professional looking report for users to utilize as they see fit.
