The Town of Forest City, North Carolina began a comprehensive wastewater treatment program with the construction of the Riverside Drive Water Reclamation Facility in 1959. Operations began in 1960 with improvements in 1983, 1988, 1991, 1997 and 2020. Design capacity is 4.95 million gallons per day (MGD), and the current flow is 1.25 MGD.
FOREST CITY WASTEWATER TREATMENT
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 (none in service at this time due to flow decrease)
Second stage aeration basin with floating aerators (4.0 MGD Capacity)
Dual secondary clarifiers (75ft diameter)
Chlorine contact chamber and step aeration.
Chlorine gas feed equipment.
Sulfur Dioxide gas feed equipment for dechlorination.
Large Aerobic Digester with Aquatec submersible aerator (approximately 0.450 MG capacity.)
Small Aerobic Digester with 60hp floating aerator (approximately 0.230 MG capacity.
(2) Waste pumps approximately 500 GPM each direct to the digester and 300 GPM to thickener.
JWC Environmental IFT series rotary screen sludge thickener.
Enviroquip 2.0 meter belt filter press (14% - 17% solids.)
Sludge storage building for Class B cake land application.
The average flow is approximately 1.25 MGD.
The citizens of Forest City can be proud of the high standards and excellent environmental record of this facility. The Town is committed to protect the environment and provide this essential service in a cost-effective and safe manner.

RIVERSTONE INDUSTRIAL PARK WWTP
NC0087084 Riverstone WWTP is located at 219 Broad River Blvd. inside the Riverstone Industrial Park. The plant is a 0.05 MGD permitted SBR plant consisting of:
Influent mechanical bar screen and manual bypass screen.
Pre-EQ basin with a maximum capacity of 0.017 MG.
SBR basin with a minimum capacity of 0.043 MG and a maximum capacity of 0.063 MG.
Decant flow rate (average high to low) 313 GPM. Sludge waste rate of 100 GPM.
Post SBR EQ basin maximum volume of 0.0156 MG. The flow control valve feeds the chlorine contact chamber at a rate of 0-0.033 MG.
The SBR has a default program for a permitted flow rate of 5 cycles/24 hour day:
Mixed-Fill 35 minutes (anoxic condition)
React-Fill 109 minutes (bowers running with floating mixer)
React Phase 35 minutes (influent pumps are locked out)
Settle 45 minutes
Decant 64 minutes
Idle 0-64 minutes (integral with decant)
Sludge Waste 2.26 minutes (integral with decant)
The cycles have programmability built in by PLC. These have been adjusted to accommodate the small flow rate currently received by the plant. Sludge waste is conducted manually as needed and is hauled to the plant headworks of the Forest City WWTP. The Riverstone WWTP was built in 2003 and began operation in November 2013. Influent flow ranges from 0.003 MGD to 0.0055 MGD of domestic and permitted industrial wastewater from industries within the industrial park and adjacent American Zinc Products facility.
