Clean Water State Revolving Fund (CWSRF): Energy Conservation
The CWSRF can finance energy efficiency and conservation projects that reduce the amount of thermoelectric energy used at publicly owned treatment works (POTW). Eligible projects include:
- Energy efficient equipment and components (e.g., lighting, HVAC, process equipment);
- Onsite renewable energy (e.g., wind, solar);
- Methane capture and energy conversion equipment;
- Biosolids drying/dewatering and energy conversion equipment;
- Co-digestion;
- Combined heat and power (CHP) systems; and
- Pro rata share of capital costs of offsite clean energy facilities that provide power to a treatment works.
Funding Energy Efficiency and Conservation Projects with the Clean Water State Revolving Fund
This fact sheet demonstrates how the CWSRF provides assistance to eligible recipients for projects promoting energy efficiency and conservation. It highlights successful projects in New York, Alabama and Maryland.
Success Stories
Power Up with Methane Gas: Struthers Water Pollution Control Facility
The city of Struthers received $5.4 million in ARRA funding from the Ohio’s CWSRF for a project that uses methane gas produced at the Struthers Water Pollution Control Facility to power unit treatment processes and significantly offset the facility’s energy footprint.
Combined Heat and Power Projects at Wastewater Treatment Facilities
This fact sheet describes how the CWSRF applies to the development of combined heat and power (or cogeneration) projects and provides examples of projects that have been funded through the CWSRF.
