PROJECT DESCRIPTION

The Wastewater Compliance and Sustainability Project will address sanitary sewer overflows to

resiliency. With this WIFIA loan, the City of Chattanooga will modernize the Moccasin Bend
Wastewater Treatment Plant which serves customers throughout the City of Chattanooga and
adjacent communities in Hamilton County, Tennessee, and Walker County and Catoosa County,
Georgia. The City of Chattanooga will improve storage and treatment capacity at the plant to
provide resiliency during extreme weather events and support compliance with its consent
decree. To improve operational efficiency, the city will design and construct technology to
generate Class A biosolids and increase biogas production by at least 15%. By financing with a

WIFIA program's flexibility to defer principal repayment untii 2032, six years after construction
completion.
