Hemingway WWTP - Secondary Wastewater Treatment in Hemingway, South Carolina

Hemingway WWTP is a municipal wastewater treatment facility located in Hemingway, South Carolina, serving a population of approximately 2,400. The plant provides secondary treatment, a standard level for communities of this size in the United States, ensuring removal of organic matter and suspended solids before discharge. As a secondary treatment plant, Hemingway WWTP operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. These permits set effluent limits to protect water quality. The plant's average daily discharge volume is about 870,650 gallons, reflecting its role in managing local wastewater. The treated effluent is released into nearby streams that flow into the Pee Dee River, eventually reaching the Atlantic Ocean via Winyah Bay. The plant's inland location, more than 10 km from the coast, reduces direct marine impact, but its discharge contributes to the overall health of the Pee Dee River watershed, which supports diverse aquatic life and recreational activities.

The plant discharges into local tributaries of the Pee Dee River, which flows southeast through South Carolina to Winyah Bay and the Atlantic Ocean. The Pee Dee River basin supports a variety of fish species, including striped bass and American shad, and provides critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient loading, which is important for preventing eutrophication in downstream estuarine environments.
