Operational Narrative
Town of Spring Lake Regional Wastewater Treatment Plant
The Town Spring Lake Regional WWTP was constructed in 1976 and designed by Rose and Purcell, Inc. of
Fayetteville, North Carolina. The facility was originally designed with United States Environmental
Protection Agency (EPA) funding to meet the Clean Water Act and was intended to function as a regional
plant to serve the Town and surrounding areas. The plant utilizes a modification of the activated sludge
process known as extended aeration. It is a dual train facility with a capacity of 0.75 million gallons per
day (MGD), per train, for a total average daily flow (ADF) of 1.5 MGD. This design flow was determined
based on an anticipated population of the Town of Spring Lake of 15,000 in the year 2000, and a
wastewater flow of 100 GPD/capita.

The treatment process currently includes the following unit processes and equipment:
• Influent Screw Pumps
Grit Removal
• Influent Screen/Screenings Press
Fixed Bar Screen
• Influent Flow Measurement (Parshall Flume)
• Activated Sludge Biological Treatment (Extended Aeration)
• Final Clarifiers
• Return Waste Activated Sludge Pumps
• Post Aeration
• Chlorination/Dechlorination
• Effluent Flow Measurement (Parshall Flume)
• Sludge Stabilization/Disposal
• Emergency Generator
Two parallel screw pumps lift the raw sewage 23.8 feet in elevation to the influent channel which was
designed to feed the "Pista Grit" vortex grit removal unit. The flow then passes through a mechanical
helical screen and screenings press compactor. A fixed bar screen handles excess flow and serves as.a
backup to the mechanical screen. Flow is measured by a Parshall flume before it enters the activated
sludge process train. Flow may be split or directed to one of the two activated sludge process trains
which operate in parallel.
Air is introduced into the aeration basins by eight floating surface aerators. The effluent from the two
activated sludge process trains is combined before it is split to three final or secondary clarifiers. The
overflow or effluent from the clarifiers flows by gravity to the post aeration basins and then to the
chlorine contact chamber where it is disinfected. The effluent is then dechlorinated with sulfur dioxide
and measured in the effluent Parshall flume before it flows (by gravity) to the Lower Little River.
The.underflow from the clarifier (sludge) flows by gravity to the sludge wet well in the sludge pumping
building. The collected activated sludge is either re -circulated to the activated sludge process at the
head of the aeration basins as return activated sludge, or fed to the sludge holding tank (the old aerobic
digester) as waste activated sludge (WAS). In the sludge holding tank some of the volatile solids are
reduced by aeration (oxidation) and this prevents the sludge from going septic or anaerobic. This

reduces the potential for odors and sustains good handling characteristics. For pathogen and vector
attraction reduction, the sludge is lime stabilized to Class B standards and held in a biosolids storage
tank prior to application.
Biosolids are presently land applied to 64.14 acres of permitted land of which 15.84 acres are on the
WWTP site and the remainder of the land is on nearby farms. Coastal Bermuda and Fescue Grasses are
grown on these properties.
WASTEWATER TREATMENT PLANT COMPONENTS
Influent Screw Pumps
The influent screw pumps were last upgraded and replaced in August of 2001. These pumps are
designed to lift a maximum of 2,500 gpm or 3.6 MGD each. Together they can pump a total of 5,000
gpm or 7.2 MGD. During the 2001 upgrade the new screws were designed to accommodate projected
increased flows. The sheaves of the motors can be changed to bring the capacity of a single pump to
5.77 MGD, with a combined total of 11.54 MGD. The motors for these pumps were also upgraded in
2001, so they would not need to be changed in the future. The upgraded motors would not need to
work as hard and will require less maintenance and last longer.
The design criteria for the screw pumps are as follows:
• Pump Type Screw Pumps
• Manufacturer Lakeside Equipment Company
• Number 2
• Motor Horsepower 40
• Diameter 48 Inches
• Pump Rate 2,500GPM
5,000 GPM (2 pumps operating)
• Pump Rate 3.6MGD
7.2 MGD (2 pumps operating)
• Peak Factor 2.4 (1 pump operating)
4.8 (2 pumps operating)
Notes: Pumps were replaced in 2001. The new pumps were fitted with an extra flight. Pumps may be
upgraded by changing a sheave with a different diameter to pump at a rate of 4,010 GPM or 5.77 MGD
with one pump operating or 8,020 GPM or 11.54 MGD with two pumps operating.

Grit Removal
The "Pista-Grit" chamber which is a proprietary piece of equipment by Smith and Loveless Inc. This unit
is a vortex grit removal unit complete with a mixer and blower system, decanter, screw conveyer and
hopper.
• Type Pista Grit Chamber
• Manufacturer Smith & Loveless
• Number 1
• Motor 14 Horsepower
• Diameter 8 Feet
• Blower Motor 3 Horsepower
• Blower Output 50 CFM @4.0 PSI
• Peak Rate
4.0MGD
Note: Grit and water separator, and grit screw are sized for the Pista Grit Chamber per manufacturer's
requirements.
Influent Screen / Screenings Press
The influent screw screenings press, which has a peak flow capacity of 3.0 MGD, was installed in March
of 1998. The existing equipment replaced an older "Barminutor" which is a type of comminutor. A
comminutor is designed to grind up large solids and not remove them. A screening device is preferred,
as ground up plastics in sludge or biosolids make land application less desirable due to the potential
trash and litter in the field.
The screw screen functions well under normal flows. However, at higher flows the upstream water level
increases and it is then diverted to the manual bar screen in the bypass channel.
Type Helisieve - Cylindrical Screen with Screw Conveyor and
Compactor Press
• Manufacturer Hycor Corporation (Currently PilTkson Corporation)
• Number 1
• Motor 1 Horsepower
• Channel Width 24 Inches
•' Basket Diameter 15.55 Inches
• Average Flow 1.0+ MGD
• Peak'Flow 3.0MGD

Note: During peak flows an adjacent channel is opened which has a static or manual bar screen.
Activated Sludge
The Town of Spring,Lake Regional WWTP uses extended aeration as its activated sludge process. The
two activated sludge basins have a combined volume of 1,853,544. This provides a hydraulic detention
time of approximately 30 hours at design flow. The basins were designed to have a minimum oxygen
content of 2 mg/I. To meet this, four aerators have been installed within each basin, with one as a
standby.

The plant was originally designed with two final or secondary clarifiers. In 2005 a larger clarifier was
added. This was required because the plant was not meeting design specifications during periods of high
flow due to inflow/infiltration and under designed clarifiers. The clarifiers for the original plant were
under -designed in overflow rates, weir loading and depth. Currently the plant is designed for all three
clarifiers to be in operation. The flow is split with one quarter of the flow going to each of the original
clarifiers and one half to the new larger clarifier.
The two original clarifiers were manufactured by Suburbia Systems, Inc. These clarifiers are each
135,255 gallons in volume with a detention time of 4.33 hours per tank, as originally designed. The
average surface overflow rate was originally designed at 414 gpd/ft2. Each clarifier is 48 feet in diameter
and has a side water depth of 10 feet. These 30-year-old clarifiers perform well during normal flow and
they are in reasonable condition. In 2003 a new clarifier was added to the plant to improve the plant's

performance and to handle high peak flows in excess of 3.0 MGD. At these flows, the original clarifiers
did not perform sufficiently. They are relatively shallow and did not provide adequate weir loading
volume and overflow.
The new clarifier was built in 2005 and manufactured by Walker Process Equipment This"clarifier is
431,765 gallons in volume with a detention time of 6.9 hours at its design flow rate of 1.5 MGD, when all
three clarifiers are in operation. The average surface overflow rate is 390 gpd/ft2. The clarifier is 70 feet
in diameter and has a side water depth of 15 feet. The clarifier performs well and is in good condition.
The stationary bridge is a good upgrade from the older clarifiers, which reduces replacement and
maintenance costs of the skimmer arm motor.

Return Waste / Activation Sludge Pumps
Sludge from the clarifiers flows by gravity to the return/waste sludge wet well. Sludgermay be pumped
to the head of the aeration basins as return activated sludge (RAS) or wasted to the old aerobic digester
which serves as sludge storage.
The four return/waste activated sludge pumps are 5 horsepower centrifugal pumps that pump at 521
gpm or .75 MGD.

Type Centrifugal
• Number of Pumps 4
• Pump Motor 5 Horsepower
• Pump Rate 500 GPM at 21 Feet
• Recycle Ratio 0.96+/- with 2 pumps
Note: The recycle rate can vary with frequency and duration of wasting/returning sludge.
Disinfection
Water from the post aeration basins flows into the chlorine contact chambers. The combined volume of
the two chlorine contact chambers is 14,960 gallons. The basins were designed to have a minimum
detention time of 23 minutes at a peak flow and consist of a flash mixing basin and concrete baffles to
ensure proper mixing of chlorine and wastewater effluent. Chlorine gas is dissolved into potable water
before it is injected into the flash mixing basin. The one ton cylinder system originally designed for the
WWTP was replaced with a dual 250-pound vertical cylinder system similar to the dechiorination system
in 1995. This was done for safety concerns and to eliminate the extra regulatory requirements
associated with the one ton cylinders. The other components of the chlorination systems are functioning
properly.
After the water is chlorinated, sulfur dioxide is introduced into the effluent channel in order to de -
chlorinate the water by reducing chlorine to chloride through instantaneous reaction.
• Trains 2
• Basin Size 24,000+/- Gallons
• Chlorination Chlorine Gas
• Contact Time 46± Minutes ADF -
• Peak Contact Time 23±-Minutes Peak
• Dechlorination Sulfur Dioxide Gas
Note: Chlorination and dechiorination are adequate. Feed rates are adjustable and within the desired
ranges.
Sludge (Biosolids) Stabilization/Disposal
The WWTP was originally designed to use aerobic digestion for sludge biosolids stabilization. However
the digester was significantly under designed to meet the pathogen reduction and vector attraction

requirements, which were established by tile EPA in the 40 CFR 503 sludge regulations. These
regulations became effective in the early 1990's.
The sludge stabilization/disposal facility was constructed in September of 1995. The sludge stabilization
process has functioned -well and there have been essentially no problems with the equipment, except
for routine maintenance.
In the current sludge stabilization process the biosolids are thickened or concentrated in the sludge
storage tank (old digester) by turning off the aerator and draining supernatant (liquid phase). Thickened
sludge is pumped by the progressive cavity sludge transfer pump to one of the two sludge
mixing/stabilization tanks. A lime slurry solution is pumped into the sludge transfer line at a
concentration which raised the pH to above 12. The Time/sludge mixture is re -circulated by one of the
sludge transfer pumps for 12 hours before being pumped to the stabilized biosolids holding tank.
Stabilized biosolids may be pumped to sludge hauling trucks for land application on -site or off -site.
The lime stabilization tanks have functioned well, since their installation in 1998. These lime stabilization
tanks were required to address the 40 CFR 503 sludge regulation. As the plant increases its capacity,
additional sludge tanks and sludge storage should be considered.

PART E. TOXICITY TESTING DATA ;
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's oufalls: 1) POTWs with a design flow rate greater than or equal to 1.0 MGD; 2) POTWs with a pretreatment program (or those that are required
to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the
results show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution.
Do not include information on combined sewer overflows in this section. All information reported must be based on data collected through
analysis conducted using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other
appropriate QA/QC requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
