Install more efficient irrigation systems on every groundwater point of diversion, including pivots, wheel lines, hand-lines, and flood systems fed by groundwater.

—   Convert pivots to Low Elevation Sprinkler Application (LESA) systems where possible.

• Increase efficiency of lateral move sprinkler or wheel lines:

  —   Shorter irrigation periods (e.g., 6-8 hour sets and move wheel lines three times).

  —   Replace leaking gaskets, and broken or cracked sprinkler heads.

  —   Use smaller diameter nozzles (especially earlier in the season).

  —   Change set-up to optimize for a low pressure system (e.g., 30-35 psi).

Utilize Variable Frequency Drives (VFDs):

—   VFDs enable a pump to deliver water using less horsepower, saving energy and power costs while delivering the appropriate amount of water.

—   There are currently various incentive programs (e.g., rebates, cost-shares, etc.) to help with the cost of replacement and installation.

—   On turbine pump motors, it has been estimated that the VFD can pay for itself in 7-8 years, on average.

Consider piloting improved precision irrigation tools.

—   Participate in workshops to test and tailor evapotranspiration monitoring tools (such as OpenET and applications designed to use AgriMet station data) to aid in water and energy conservation, and maximize “crop per drop”.
