ROSE HILL STP and Collection System is a municipal wastewater treatment facility located in Rose Hill, Lee County, Virginia. The plant serves a small community of approximately 816 residents, providing secondary treatment to meet state and federal water quality standards. As a secondary treatment plant, it employs biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 227.12 thousand cubic meters per day and currently discharges 113.56 thousand cubic meters per day, indicating operational headroom. Under the U.S. Clean Water Act, such facilities operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Virginia Department of Environmental Quality, which set effluent limits to protect receiving waters. The plant's treated effluent flows into local streams that are part of the Tennessee River watershed, ultimately draining into the Ohio River and then the Mississippi River. This waterway supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the ecological health of the region.

The plant discharges into small streams within the Tennessee River basin, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This watershed supports a variety of fish and wildlife species, including several freshwater mussels and fish that are sensitive to water quality. The secondary treatment process helps mitigate the impact of nutrient enrichment and organic pollution on these downstream ecosystems.
