Huff Creek WWTP - Mauldin, South Carolina Wastewater Treatment Plant

Huff Creek WWTP is a municipal wastewater treatment facility located in Mauldin, South Carolina, within Greenville County. The plant serves a population of approximately 35,125 residents, classifying it as a medium-sized agglomeration under US regulatory frameworks. Its location in the upstate region of South Carolina places it within the broader Reedy River watershed, which ultimately drains into the Saluda River and Lake Greenwood. As a US facility, Huff Creek WWTP operates under the Clean Water Act, administered by the EPA and likely permitted through the South Carolina Department of Health and Environmental Control (DHEC) under the National Pollutant Discharge Elimination System (NPDES). For a plant serving over 10,000 people, secondary treatment is typically required, with additional nutrient removal standards applicable in sensitive watersheds. The plant's treatment processes are designed to meet these regulatory requirements, protecting downstream water quality. The treated effluent from Huff Creek WWTP is discharged into a local waterbody that feeds into the Reedy River, a tributary of the Saluda River. The Saluda River flows into Lake Greenwood, a major reservoir that supports recreation, drinking water supply, and aquatic habitat. The plant plays a critical role in maintaining water quality in this chain of water bodies, particularly given the ecological sensitivity of the Reedy River and its importance to the region's water resources.

Huff Creek WWTP discharges into a local tributary of the Reedy River, which flows into the Saluda River and ultimately reaches Lake Greenwood. This watershed supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for migratory birds. The plant's operations are crucial for preventing nutrient pollution and maintaining dissolved oxygen levels in the Reedy River, which is a key water resource for the Greenville area.
