Public Water Infrastructure Plant Efficiency Program

wastewater treatment plant

Illinois EPA’s Office of Energy is teaming up with ISTC and Smart Energy Design Assistance Center (SEDAC) to help local municipalities reduce the cost of water and wastewater treatment. SEDAC and ISTC will provide free energy usage assessments to publicly-owned water treatment and wastewater treatment plants.

The cost of wastewater treatment can be a significant burden for municipalities, especially when the infrastructure is aged or inappropriately sized for the community it serves. This partnership is designed to help municipalities identify efficiency improvements to their systems and potential cost savings for their communities.

The final assessment reports will break down recommendations for energy efficiency improvements at each facility. This will include information such as upfront costs for equipment upgrades or retrofits, the estimated time it will take for the upgrade costs to pay off in energy savings, and the resulting energy and monetary savings that could result from upgrades and retrofits. Similar assessments would ordinarily cost municipalities between $6,000 and $12,000.


To qualify for an assessment, a public water or wastewater treatment facility must:

  1. Be located in Illinois and owned by the State of Illinois or an Illinois unit of local government;
  2. Allow SEDAC and ISTC access to the treatment facility;
  3. Be willing to share facility information with SEDAC, ISTC and Illinois EPA; and
  4. Share the final assessment report with the Illinois EPA.


Apply now! Applications are open for the Public Water Infrastructure Energy Assessment.
