18 MI CRK UPPER REG WWTP is a municipal wastewater treatment facility located in Pickens County, South Carolina, United States. The plant serves a small population of approximately 1,133 residents, providing essential sanitation services to the local community. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for plants discharging into sensitive watersheds. The plant operates under the U.S. Clean Water Act, with permits issued by the South Carolina Department of Health and Environmental Control (DHEC) to ensure compliance with federal and state water quality standards. The treated effluent is discharged into a local waterway that ultimately drains into the Savannah River Basin. This basin supports diverse aquatic life and provides drinking water for downstream communities. The plant's advanced treatment helps protect the ecological health of the receiving waters and the broader watershed.

The plant discharges into a tributary of the Savannah River Basin, which flows through South Carolina and Georgia before reaching the Atlantic Ocean. The basin supports a variety of fish and wildlife, including several species of freshwater mussels and migratory fish. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and aquatic habitats.
