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.
Equipment purchased before April 5, 2021 is not eligible for incentives.

You must return a completed and signed incentive application with your invoices for your equipment to Energy Trust within 180 days of purchase and before the end of the calendar year to receive your incentive.
Receive your incentive.
See the cash incentive available for converting your linear or pivot to a MESA, LESA, LEPA or PMDI irrigation system outlined in the tables below. There are no limits on the number of incentive applications you can submit for MESA, LESA, LEPA or PMDI upgrades.
Maximum incentive limits differ by participating utility:
- Portland General Electric sites are limited to $40,000 in 2021.
- Pacific Power sites are limited to $10,000 in 2021.
|Upgrade for systems with VFD||Incentive|
|High pressure to MESA||$25 per sprinkler drop|
|High pressure to LESA/LEPA/PMDI||$25 per sprinkler drop|
|MESA to LESA/LEPA/PMDI||$15 per sprinkler drop|
|Upgrade for systems without VFD||Incentive|
|High pressure to MESA||$11 per sprinkler drop|
|High pressure to LESA/LEPA/PMDI||$10 per sprinkler drop|
|MESA to LESA/LEPA/PMDI||$7 per sprinkler drop|
