The city of Chattanooga has unveiled plans to install a system that will convert wastewater into a renewable energy source at its Moccasin Bend Environmental Campus.
The system will produce biogas from organic solids found in wastewater that will be converted to power the wastewater plant’s operations. Potentially, the resulting power could also be processed and sold as a natural gas substitute.
The project is estimated to cost between $130 million and $150 million. Funding will come from federal, state and local sources, including the EPA’s Water Infrastructure Finance and Innovation program, Tennessee’s Clean Water State Revolving Fund (SRF) and the city’s sewer system enterprise fund.
The city plans to issue a request for proposal (RFP) solicitation document and later select a contractor for the design build project.
