BLOWING ROCK WWTP - Secondary Treatment Plant in Blowing Rock, North Carolina

BLOWING ROCK WWTP is a municipal wastewater treatment facility located in Blowing Rock, North Carolina, a town in the Blue Ridge Mountains. The plant serves a population of about 2,028 residents and operates under secondary treatment standards, which is typical for smaller communities in the United States. The plant's designed capacity is 3,028.32 thousand gallons per day, and it currently discharges an average of 681.37 thousand gallons per day. As a secondary treatment facility, it meets the requirements of the U.S. Clean Water Act, which mandates secondary treatment for municipal wastewater plants to reduce organic pollutants and suspended solids before discharge. The treated effluent is released into a local waterway that ultimately drains into the Upper New River basin, part of the larger Ohio River watershed. This region is ecologically significant, supporting diverse aquatic life and providing recreational opportunities. The plant's operation helps protect downstream water quality in this sensitive mountain ecosystem.

The plant discharges into a tributary of the Upper New River, which flows into the New River and eventually the Ohio River. This watershed is part of the Appalachian region, known for its biodiversity and cold-water fisheries. The secondary treatment process reduces nutrient and pollutant loads, helping to maintain water quality in this ecologically sensitive area that supports trout and other aquatic species.
