SEDAC provides no-cost energy assessments to publicly-owned Illinois water and wastewater treatment systems.

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 treating water and wastewater.

We provide no-cost energy usage assessment to publicly-owned water and wastewater treatment systems across Illinois. Assessment reports break down recommendations for energy efficiency improvements at each facility, including information such as estimated project costs, simple payback periods, funding opportunities, and the resulting energy and monetary savings.
