Low Energy Precision Application (LEPA) and Low Elevation Spray Application (LESA)

$15-$35 rebate incentive

Traditionally, pivots and linears have used high-pressure impact sprinklers mounted on top of the main pipe. Dropping the sprinklers closer to the ground using goosenecks and drop tubes can save water and energy by increasing the application efficiency and reducing the required system pressure.

Mid-Elevation Spray Application (MESA) systems use sprinklers that operate within 5-10 feet of the ground, Low Elevation Spray Application (LESA) systems use sprinklers that operate within one foot of the ground, and Low Energy Precision Application (LEPA) systems use sprinklers or bubblers that operate at the ground level. Precision Mobile Drip Irrigation (PMDI) systems take it a step further and use ground-level drip tubing attached to the end of the drop tubes.

Energy Trust offers a per-drop rebate for upgrading to these irrigation systems depending on which system is being upgraded to and whether the pump serving the system has a Variable Frequency Drive (VFD, also known as a variable speed drive) or not.

Your contractor can assist you in completing and submitting required Form 420PL.
