An energy assessment provided by SEDAC or ISTC will include a facility walk through, utility bill analysis, and an assessment report with:
• Energy e� ciency recommendations• Projected energy and cost savings and incentives• Projected capital cost and payback time
Facilities must:• Be owned by the State or local government• Allow SEDAC or ISTC access to the facility• Share facility information with SEDAC or ISTC• Share � nal report with Illinois EPA
What is an energy assessment?
The Illinois EPA O� ce of Energy, in partnership with the Smart Energy Design Assistance Center (SEDAC) and the Illinois Sustainable Technology Center (ISTC), is helping local municipalities reduce the cost of wastewater treatment. For a limited time, receive a free energy assessment, a $6,000 - $12,000 value.
Reduce the energy cost of wastewater
treatment
Funding provided in whole or in part by the Illinois EPA O� ce of Energy. This program is in partnership with the U.S. Dept. of Energy Sustainable Wastewater Infrastructure of the Future [SWIFt] Accelerator for energy e� ciency in wastewater treatment. Illinois EPA: http://bit.ly/WWTP-EE

1. AERATION. Use dissolved oxygen sensor aeration controls and � ne bubble aeration to reduce energy consumption.
2. BLOWER. Upgrade to a high-e� ciency, variable capacity blower.
3. ELECTRIC MOTOR CONTROL. Use variable frequency drives on aeration blower motors and pump motors.

How does your wastewater treatment plant compare?
SEDAC and ISTC have provided energy assessments for dozens of wastewater treatment plants. In this � gure, we compare the energy use intensity (kWh per million gallons processed) of 17activated sludge wastewater treatment plants. The highest performing facility is over � ve times more e� cient than the lowest performing facility. Larger plants (in blue) were generally more e� cient, though all had room for improvement.
Receive a free energy assessment to � nd out how your facility compares and to learn about energy savings opportunities.
