The facility is located at 2800 River Ridge Road, in Winston Salem, Forsyth County, North Carolina. The facility is authorized to discharge wastewater from the treatment works through outfall 001 to an unnamed tributary (UT) of Bashavia Creek, which is currently classified as Class C waters in the Yadkin Pee -Dee River basin. The wastewater treatment system consists of one equalization basin and two settling lagoons with a sodium bisulfite dechlorination system. The waste stream consists of backwash water from the water treatment system's filters and sludge from the water treatment system's sedimentation basins. Documentation & Monitoring Review 3. All required records were readily available, complete, and current. Discharge monitoring records for 2015 were reviewed and no discrepancies were noted. Site Review 4. Filter backwash wastewater goes to the equalization basin, then to the lagoon(s), and is then discharged. The sedimentation basin blowdowns (sludge) go directly to the lagoons for settling and are then discharged. Wastewater is dechlorinated using sodium bisulfate before discharge.
