IEPA Wastewater Treatment Energy Assessment Program
November 5, 2019
Illinois EPA has teamed up with the Smart Energy Design Assistance Center (SEDAC) and the Illinois Sustainable Technology Center (ISTC) to help local municipalities reduce the cost of wastewater treatmentFREE energy assessment for your publicly-owned wastewater treatment facility
• Similar assessments: $6,000-$12,000
Comprehensive report listing: • Cost of upgrades• Estimated payback period • Any applicable incentives and
available funding opportunities

About the Program
• Step 1: Initial Application – Pre-Qualification
• Be located in Illinois• Allow SEDAC/ISTC to visit site• Be willing to share facility information• Share final assessment report with
Illinois EPA
• Step 2: Data Collection • Facility information – energy use,
discharge reports, process info• We’re here to assist!
• Step 3: Site Visit Scheduled
