7. Describe the treatment system List all installed waste treatment components with capacities,
describe the processes that generate wastewaters. If the space provided is not sufficient attach a
separate sheet of paper with the system description.
Wastewater is first stored in a solids/primary holding tank, solids are separated out
during this stage of the treatment process. Wastewater (minus solids) then moves to an
equalization tank, from here wastewater is pumped to a MBBR tank where it is aerated. -
The wastewater then flows into an Aquapoint Bioclere trickling filter (a portion of the
wastewater gets pumped back to the solids tank through a recycle line) , effluent from
the Bioclere trickling filter then flows by gravity to a wetwell where it is then pumped
through a U/V disinfection system.
Equipment list:
(1) (1) 5,000-gallon primary tank
(2) (2) 3,000-gallon EQ tank

Attachment A - for Minor Industrials with a Water Treatment Plant
1. Type of treatment plant:
❑ Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by
filtration and disinfection)
❑ Ion Exchange (Sodium Cycle Cationic ion exchange)
❑ Green Sand Filter (No sodium recharge)
X Membrane Technology (RO, nanofiltration)
Check here if the treatment process also uses a water softener X
2. Description of source water(s) (i.e. groundwater, surface water)
Groundwater
2. Describe the treatment process(es) for the raw water:
Raw water is pumped through a series of carbon filters then water softeners and final reverse
osmosis. The treated water is then chlorinated before it goes into distribution.
4. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
Wastewater is first stored in a solids/primary holding tank, solids are separated out
during this stage of the treatment process. Wastewater (minus solids) then moves to an
equalization tank, from here wastewater is pumped to a MBBR tank where it is aerated.
The wastewater then flows into an Aquapoint Bioclere trickling filter (a portion of the
wastewater gets pumped back to the solids tank through a recycle line) , effluent from the
Bioclere trickling filter then flows by gravity to a wetwell where it is then pumped through
a U/V disinfection system.
5. Number of discharge points to surface waters:1
Outfall Identification number(s) 001
6. Frequency of discharge: Continuous Intermittent x
If intermittent:
Days per week discharge occurs: 7 Duration: 10 minutes
7. Plant design potable flowrate 0.0035 MGD
Backwash or reject flow 0.001 MGD
8. Name of receiving stream(s) (Provide a map showing the exact location of each outfall, including
latitude and longitude): Northeast Cape Fear River. Latitude 34 degrees 15' 10"N, Longitude
77 dedress 57'10"W

Attachment A - for Minor Industrials with a Water Treatment Plant
9. Please list all water treatment additives, including cleaning chemicals or disinfection
treatments, that have the potential to be discharged.
Alum / aluminum sulfate Yes No X
Iron sulfate / ferrous sulfate Yes No X
Fluoride Yes No X
Ammonia nitrogen / Chloramines Yes No X
Zinc-orthophosphate or sweetwater CP1236 Yes No X
List any other additives below:
Sodium hypochlorite
10. Additional Information:
Provide a schematic of flow through the facility, include flow volumes at all points in the water
treatment process. The plan should show the point[s] of addition for chemicals and all
discharges routed to an outfall [including stormwater
Solids Handling plan
Solids from the solids/primary tank are pumped out on a monthly basis; approximately one
quarter of the volume is removed (approximately 1000-1200 gallons). The pumping service and
solids disposal is provided by Lewis Farms and liquid wastes, Currie NC. Lewis Farms and liquid
wastes also clean the grease trap on a monthly basis.
