With the use of non-organic products such as paper towels and disposable wipes on the rise, wastewater pumping systems are often working harder to minimize clogging. This wears down pumps faster and increases energy use.

Municipal and industrial wastewater facilities across Oregon can achieve significant energy savings by installing energy efficient systems such as self-cleaning wastewater pumps, variable frequency drives (VFDs) and advanced controls at their facilities.

  1. Establish your eligibility.

    Energy Trust provides cash incentives to Oregon businesses for energy-efficiency and renewable energy projects. To qualify, you must:

    • Be served by Portland General Electric or Pacific Power and contribute to the public purpose charge. Check your utility bill or contact us if you have questions.
    • Have a project site in Oregon.
  2. Select equipment that qualifies for Energy Trust incentives.

    Your trade ally or vendor can help you get started.

  3. Receive an incentive offer from Energy Trust.

    Review the offer, provide your utility account number, signed W-9, mailing address, site address and estimated project completion date. You must return the signed incentive offer to the Energy Trust contact listed on the form before ordering or purchasing the equipment.

  4. Purchase and install the equipment.

    After you return the signed incentive offer, then purchase and install the equipment.

  5. Sign the Project Completion Form.

    Once your project is completed, you will receive a Project Completion Form from Energy Trust, which must be returned with your invoice(s) for the equipment purchased.

  6. Receive your incentive.

Customers may receive cash incentives up to $250,000 per site, per year. Cash incentives are calculated based on operating hours and usage. Incentives are subject to funding availability and may change.

See incentive amounts available to municipal and industrial facilities for pump system upgrades (up to 100 hp) outlined in the table below.

System Incentive
Self-cleaning wastewater pump (new or retrofit), variable frequency drives (VFDs) and advanced controls $0.38 per kWh saved, up to 70% of eligible project cost

If you’re planning a larger pump or system upgrade (over 100hp), Energy Trust can help with technical assistance and work with you to create a customized incentive offer for your scoped project. For more information about larger projects, visit our custom energy-efficiency projects page.
