STATE PROGRAM: Tennessee Department of

ASSISTANCE RECIPIENT: Humboldt Utilities

ASSISTANCE AMOUNT: $15,7M

PROJECT DESCRIPTION

The Town of Humboldt is a disadvantaged community in West Tennessee with a population of approximately
9,300. The Town's 2.6 MGD wastewater treatment plant needed major renovations due to the plant's age,
discharge to an impaired receiving stream, and new discharge limits for nutrients. As the Town was designing
renovations to the aging plant, Tyson Foods announced the construction of a new facility in Humboldt with a
discharge of up to 2 MGD of waste. To accommodate the increased flow, Humboldt constructed a new 5 MGD
Sequencing Batch Reactor (SBR) wastewater treatment plant to handle the increased waste from the industry.
These improvements were made possible with a $15,700,000 CWSRF assistance agreement that includes
$300,000 in loan forgiveness. The new plant with additional capacity allowed for a well-needed economic
boost for Humboldt and the surrounding area, creating 1,600 new jobs with Tyson Foods and producing a
cleaner effluent for the impaired receiving stream.
