RHODISS WWTP - Secondary Wastewater Treatment in Granite Falls, North Carolina

RHODISS WWTP is a municipal wastewater treatment facility located in Granite Falls, North Carolina, within the United States. The plant serves a small population of 725 residents, reflecting its role in a rural or small-town 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 363.40 units, with an actual discharge volume of 151.42 units, indicating operational headroom. As a secondary treatment facility serving a small population, it meets typical requirements for inland plants in the region. The treated effluent is discharged into a local waterway that ultimately drains into the Catawba River basin, a major watershed in North Carolina. The Catawba River flows into Lake Wylie and eventually reaches the Atlantic Ocean via the Santee River system. The plant's discharge supports the ecological health of the receiving stream, contributing to downstream water quality and aquatic habitat.

The plant discharges into a tributary of the Catawba River, which flows through the Piedmont region of North Carolina. The Catawba River basin supports diverse aquatic life, including fish species such as striped bass and catfish, and provides drinking water for downstream communities. The river ultimately reaches Lake Wylie and the Santee River system, which drains into the Atlantic Ocean. The plant's secondary treatment helps protect this watershed from nutrient pollution and organic loading.
