GRUNDY CO WWTP is a municipal wastewater treatment facility located on Industrial Park Road in Grundy County, Tennessee. Serving a population of approximately 1,199, the plant is part of the region's infrastructure for managing domestic wastewater in the Middle Tennessee area. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal facilities of this scale. With a designed capacity of 378.54 thousand cubic meters per day and an average discharge volume of 340.69 thousand cubic meters per day, the plant operates efficiently within its capacity. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Tennessee Department of Environment and Conservation. The treated effluent is discharged into local streams that drain into the Tennessee River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting water quality in the region, supporting aquatic life and downstream ecosystems.

The plant discharges into tributaries of the Tennessee River, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. The Tennessee River basin supports diverse aquatic life, including numerous fish species and migratory birds. The plant's secondary treatment helps reduce nutrient loads and organic pollutants, protecting downstream water quality in this ecologically significant watershed.
