CLAREMONT MCLIN WWTP - Secondary Wastewater Treatment in Catawba County, North Carolina

CLAREMONT MCLIN WWTP is a municipal wastewater treatment facility located in Catawba County, North Carolina, United States. The plant serves a small population of 565 residents, reflecting its role in a rural or suburban community. It operates under the regulatory framework of the US 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 1135.62 units, with an average daily discharge of 719.23 units, indicating operational headroom. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into a local water body, likely a tributary of the Catawba River basin, which flows into the Santee River system and ultimately reaches the Atlantic Ocean. The plant's inland location, over 50 km from the coast, reduces direct marine impact. Its small scale and secondary treatment align with typical requirements for small communities under state and federal regulations.

The plant discharges into a receiving water body within the Catawba River basin, a major watershed in North Carolina that drains into the Santee River and then the Atlantic Ocean. The Catawba River supports diverse aquatic life and provides drinking water for downstream communities. As a secondary treatment plant, it reduces organic pollutants and suspended solids, helping to protect water quality in the basin. The plant's inland location minimizes direct coastal impacts, but its discharge contributes to the overall nutrient and pollutant load in the watershed, which is managed under state water quality standards.
