• Description of sewer collection system and wastewater treatment systems or processes:
Collection System: WQCS00050
The Town of Forest City maintains and operates 27 lift stations (19 in Forest City, 6 in Ellenboro, 1 at
Riverstone Industrial Park, and 1 on site at American Zinc Products .) There are~ 95 miles of gravity
sewer and ~13.6 miles of force main. Chase Middle School makes up 2.4 miles of this force main and
Chase High School makes up another 1.5 miles of this force main . The Riverstone Industrial Park
makes up 0.7 miles of the gravity sewer total and 390 .8 feet of force main. The Hicks Grove station
serving AZP (American Zinc Products) has 1.1 miles of force main contributing to the above total.
Riverstone's lift station and the Hicks Grove (AZP) station are pumped to the Riverstone VMI/TP
headworks located at 219 Broad River Blvd .
The Town of Forest City also maintains the Town of Ellenboro's sewer collection system. This system
has ~ 6.2 miles of gravity sewer, 7.4 miles of force main and four pump stations (with telemetry and
dual "high water'' alarms). Ellenboro Elementary School and East High School each have lift stations
that pump into Ellenboro's collection system and are maintained by the Town of Forest City.
Pretreatment Program:
There are 4 significant industrial users which contribute flow to the collection system and Forest
City wastewater treatment plant: Everest Textiles, Eaton Corporation, Westrock and Parker
Hannifin . Riverstone WWTP has one IUP issued to AZP (American Zinc Products .) ProAmpac
was removed as an IUP during the 2020 year.
Wastewater Treatment Plants (WWTP) / Water Reclamation Facility (WRF):
NC0025984 Wastewater Treatment Plant located at 397 Riverside Drive in Forest City is a 4.95
MGD plant consisting of the following units :
• Influent mechanical step/bar screen and manual bypass screen.
• Aerated traveling bridge grit chamber and grease removal.
• 5 smaller first stage aeration tanks with floating aerators (currently not operating.)
• Second stage aeration basin with floating aerators (3. 99 MG capacity.)
• Dual secondary clarifiers (75 ft. diameter.)
• Chlorine contact chamber and step aeration.
• Chlorine gas feed equipment
• Sulfur Dioxide gas feed equipment for dechlorination .
• Aerobic Digester with Aquatec SAM submersible aerator and mixer (approximately 0.450
MG capacity.)
• Aerobic Digester with 60 hp floating aerator (approximately 0.230 MG capacity.)
• (2) Waste Activated Sludge pumps discharge approximately 500 gpm direct to the
digester(s), and approximately 375 gpm maximum to the rotary drum thickener.
• JWC Monster drum thickener IFT Series Rotary Screen .
• Enviroquip 2.0 meter belt filter press (14% -17% solids .)
• Class B sludge cake is hauled to permitted fields under Southern Soil Builders permit
(WQ0010926.)
• Average flow is approximately 1.25 MGD.
NC0087084 Riverstone WWTP
Located at 219 Broad River Blvd in the Riverstone Industrial Park. The Plant is a 0.05 MGD
SBR plant consisting of:
• Influent mechan ical step/bar screen and manual bypass screen.
• Pre EQ basin with maximum capacity of 0 .017 MG and max design flow rate of 138.9
gpm.
• SBR basin with minimum capacity of 0.043 MG and maximum capacity of 0 .063 MG .
Decant flow rate (average high to low) 313 gpm. Sludge waste rate 100 gpm.
• Post SBR EQ basin maximum volume 0.0156 MG. Flow control valve feeds chlorine
contact chamber at a rate of 0 -313 gpm.
• Chlorine contact chamber with tablet feeders for chlorination and dechlorination
• Aerobic digester with maximum volume of 0.033 MG.
PLC operation of this facility enable various settling cycles as needed. These have been
adjusted as needed to accommodate the small flow rate currently received by the plant. Sludge
waste is conducted manually as needed. Riverstone WWTP flow is approximately 3,000 to
5,000 gallons per day average.
NC0083272 DRG Harris Plant
A 0.91 MGD WWTP which is inoperative & currently inactive.
WWTP Sludge Management:
WQ0037135 Class B land application Southern Soil Builders
US Biolsolids Incorporated (formerly Southern Soil Builders) applies Class B cake sludge to
sites they have permitted under permit number WQ0037135 . 236 .55 dry tons were bulk land
applied using pathogen reduction option: Class B Alternative 1 -Fecal Coliform Geometric
Mean and vector attraction reduction options : Bench-Scale Volatile Solids Reduction (Aerobic
Bench Test w/ Percent Solids -2% or Less.) Southern Soil submits the NC DEQ report for this
permit. EPA online submission was uploaded on 02/11/2021 for the 2020 year
II. Performance
• Description of overall 12 month performance, noting highlights and deficiencies.
The Forest City WWTP and Collection System performed adequately during calendar year 2020 . The
staff of the WWTP, Collection System, and Pump Maintenance departments continuously look for ways
to minimize or eliminate heavy flow conditions associated with l&I.
75hp blowers were added to the large digester replacing the outdated 40hp units previously in service.
The small digester has been modified with larger decant lines and outfitted with a new sludge pump . A
new JWC Environmental Rotary Drum Thickener was install in June 2020 . Completing the treatment
plants CDBG updates.
Brackett Creek lift station had a Duperon Flex Rake screen from the CDBG grant. The screen was
placed in service 2nd quarter 2020 . The station saw new piping and valve updates that allows all pumps
to operate during severe storms improving station output thereby reducing Sanitary Sewer Overflows.
Funding has been approved and carried over for a new Dogwood pump station . Preliminary drawings
by are under review by McGill and Associates. Budget request have been made for soft starts to be
added at Brackett Creek lift station for pumps 1 and 2.
