Energy Assessment Program

The Illinois EPA Office of Energy has teamed up with SEDAC and the Illinois Sustainable Technology Center (ISTC) to help local municipalities reduce the cost of wastewater and water treatment since 2018. SEDAC and ISTC provide no-cost energy usage assessments to publicly-owned wastewater and water treatment plants. Assessment reports break down recommendations for energy efficiency improvements at each facility, including information such as upfront costs for equipment upgrades or retrofits, simple payback periods, and the resulting energy and monetary savings. Similar assessments would ordinarily cost municipalities between $6,000 and $12,000.

Learn more by reading our Assessment Brochure.


To qualify for an assessment, a wastewater or water 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.
