​Pumps and blower systems are busy working behind the scenes at water and wastewater treatment facilities. Improvements to their efficiency can create significant energy savings, and we make it easier with prescriptive and custom rebates. To get started, open the tabs below to see your rebate options and helpful resources, find a trade ally and check out some energy-saving tips to help you begin saving today.

program overview

Our rebates can reduce the upfront cost of improvements to pumps and blower systems. Rebates are available per horsepower for variable speed drives (VSDs) and motors that exceed NEMA premium motors. We also offer custom rebates for other improvements, including to piping systems, bowls and impellers.

get started with a pump test initiative
The best place to start is by finding out how efficiently your pumps perform with our pump test initiative. To qualify for the rebate, equipment is required to:
  • Work at 15 horsepower or greater
  • Have a load factor of 40% or more
how it works
  1. ​Schedule a pump test by calling 866-333-4735
  2. Receive a Solutions for Business rebate of 50% of the cost of the pump test
  3. Review pump test results defining energy-saving measures
  4. Implement energy-saving measures
  5. Receive additional rebates for measures implemented

water & wastewater tips
  • Get it tested - set up testing by calling 866-333-4735. Finding your specific baseline efficiency is the first step toward improving your pumps and blowers.
  • Be sure you have efficient pumps and blowers to realize your maximum savings.
  • Increase your aeration efficiency in a wastewater treatment plant to save up to 40% of your energy usage.
  • When varying flows throughout the day, a variable speed drive  (VSD) is highly recommended - even more so if you are throttling waterflow.
  • Upgrade your inefficient systems once tested. In the program to date, the average pump test efficiency is 54%. Upgrading this to 72% would lower your kWh usage by 25%.
  • Right sizing your pumps and blowers  to your process needs can improve your efficiency.
  • Control measures, such as those offered through Energy Information Services,  are great tools for operating and tracking efficiency.
