BLOWING ROCK WASTEWATER TREATMENT PLANT

I. General Information

Facility Name: Town of Blowing Rock Wastewater Treatment Plant

Responsible Entity: Town of Blowing Rock

Person in Charge: Thomas McRary, Wastewater Treatment Plant Manager

Applicable Permits: NPDES Permit No: NC0027286

II. System Description

Wastewater is physically screened through two sets of bar racks and then enters the equilization basin. It is then pumped by three influent pumps to four aeration basins where diffused air is added by five blowers. It then enters two clarifiers where a part of the sludge is returned to the head of the plant. The clear water on top of the clarifiers then enters the chlorine contact chamber where chlorine is fed to kill the bacteria. De-chlorine chemical is then added to take the chlorine out of the water before entering the river.

Solids are wasted to the digester daily. Honeywell Septic Tank Service hauls sludge to Lenoir WWTP for disposal.
