CHATHAM CO WWTP BYNUM - Secondary Wastewater Treatment in Pittsboro, North Carolina

CHATHAM CO WWTP BYNUM is a municipal wastewater treatment facility located in Pittsboro, North Carolina, within Chatham County. The plant serves a small population of 103 residents, reflecting its role in a rural or small community setting. It operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. Its designed capacity is 94.64 thousand cubic meters per year, with an actual discharge volume of 75.71 thousand cubic meters per year, indicating operational headroom. As a small facility, it is subject to state-level oversight by North Carolina environmental authorities, ensuring compliance with water quality standards. The treated effluent is discharged to a receiving water body in the Cape Fear River basin, which drains to the Atlantic Ocean. The plant's operations help protect local streams and downstream ecosystems from nutrient pollution and pathogens. Its inland location, over 50 km from the coast, reduces direct marine impact but still contributes to the overall health of the watershed.

The plant discharges into a tributary of the Cape Fear River, which flows through central North Carolina before emptying into the Atlantic Ocean near Cape Fear. The river supports diverse aquatic life, including fish and invertebrates, and is an important water resource for communities downstream. The plant's secondary treatment helps reduce organic loading and suspended solids, mitigating eutrophication risks in the river and estuary.
