YORK WWTP - Rock Hill, South Carolina Wastewater Treatment Plant

YORK WWTP is a municipal wastewater treatment facility located in Rock Hill, South Carolina, serving a population of about 16,000. The plant is situated in York County and plays a key role in managing wastewater for this growing community in the Piedmont region. As a plant serving a medium-sized agglomeration, YORK WWTP operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. Treatment standards are set by the South Carolina Department of Health and Environmental Control (DHEC), typically mandating secondary treatment for municipal plants of this scale. The plant's treated effluent enters local streams that flow into the Catawba River, a major waterway in the Carolinas. The Catawba River ultimately drains into Lake Wateree and then the Santee River system, which reaches the Atlantic Ocean. This watershed supports diverse aquatic life and provides drinking water for downstream communities.

The plant discharges into tributaries of the Catawba River, which flows through the Piedmont region into Lake Wateree and the Santee River system before reaching the Atlantic Ocean. This watershed supports diverse fish populations and provides habitat for species such as the Carolina heelsplitter mussel. The area's clay soils and rolling terrain influence runoff patterns and nutrient transport.
