Energy Efficiency at Waste Water Treatment Plants

Public Water Infrastructure Energy Assessments

Illinois EPA's Office of Energy has teamed up with the Smart Energy Design Assistance Center (SEDAC) and the Illinois Sustainable Technology Center (ISTC) to help local municipalities save energy and reduce the cost of wastewater treatment and supplying public water. SEDAC and ISTC will provide no-cost energy usage assessments to publicly owned water facilities.

The cost of wastewater treatment and water supply 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 break down recommendations for energy efficiency improvements at each facility and include upfront costs for equipment upgrades or retrofits, estimated time for return of investment, and savings resulting from upgrades and retrofits. Similar assessments would ordinarily cost municipalities between $6,000 and $12,000. To learn more about the program or eligibility, our partnership with SEDAC and ISTC, or to access the program application, visit SEDAC's Public Water Program webpage or ISTC’s Public Water Efficiency Program webpage.

Wastewater Treatment Plant Energy Efficiency Grant Notice of Funding Opportunity - CLOSED

The U.S. Department of Energy State Energy Program provides funding and technical assistance to advance state-led energy initiatives and maximize the benefits of decreasing energy waste, per 10 CFR 420. The Illinois EPA Office of Energy is responsible for establishing projects eligible for funding and an application process with determined criteria for this grant program.

Illinois EPA Office of Energy awards funding (minimum of $20,000 and maximum of $500,000) to publicly-owned wastewater treatment plants (WWTP) for the implementation of energy efficiency projects. Eligible energy efficiency measures identified in the projects must have been identified in an energy efficiency assessment. Projects will be scored and selected based on project cost effectiveness as determined by proposed energy savings (kWh) per dollar invested and energy cost impact. Additional points will be added to any application that includes a project serving an Illinois EPA Office of Environmental Justice Area of Concern and for projects located in municipally-owned electric utilities or electric cooperatives. Energy burden (%) of the WWTP service area will be used to break a tie.

Awarded funds will require a cost match obligation of 20% of the award. Please refer to the NOFO for additional details.
