2016 Annual Performance Report
F. Description of WWTP:
The wastewater treatment plant is rated at 8.34 million gallons per day (MGD).
Peak flow is rated at 12.5 MGD.
The Roanoke River Interceptor collects wastewater from basins located on the
north side of the Sanitary District. The Gaston sub-basin and Northampton County
are included in this service area. The Interceptor begins just west of NC 48 in
Roanoke Rapids. There are 3 primary basin pump stations and 2 secondary pump
stations along the route. Pipe sizes for the Interceptor range from 18" to 30".
Treatment processes at the wastewater plant include grit and rag removal. This
is followed by primary clarification, trickling filter biological secondary treatment,
activated solids treatment, secondary clarification, final effluent chlorination/de-
chlorination processes, and final pH adjustment.
The Chockoyotte Creek Interceptor serves the south side of the Sanitary District
and three sub-divisions located outside the Roanoke Rapids city limits; Lake View
Park, Greenbriar, and Lincoln Heights. The Interceptor begins east of Zoo Road.
There is one primary basin pump station along the route. Pipe sizes range from
12" to 30".
The system has six sewer lift stations. Three stations are located in the Gaston
sub-basin. One of these serves a Northampton County School, one serves the
Chowan Housing Projects and the other station pumps all flows from Gaston and
Northampton County via a 6" force main suspended from the NC 48 Bridge
spanning the Roanoke River to the Roanoke River Interceptor. The remaining
three pump stations are located within Roanoke Rapids sub-basins. Two of the
stations, Belmont and Poplar Springs, discharge to the Roanoke River Interceptor
while the Greenbriar Pump Station discharges to the Chockoyotte Creek
Interceptor.
During these processes solids are removed from two locations. Primary
clarification removes settleable solids from incoming wastewater to an anaerobic
digestion unit. Here the solids, in the absence of oxygen, receive pH adjustment,
mixing, and heating to produce a stabilized material. Once the solids are stable,
excess water is decanted and returned to the plant for further treatment. The
stabilized, thickened solids are treated with lime for odor control then removed
to a holding tank to await land application.
the two main Interceptors, range in size from 8" to 12". There are two main
Interceptors transporting wastewater to the WWTP.

2016 Annual Performance Report
There are two pumping stations in the wastewater plant distributing wastewater
into and through the plant. Of these two pump stations, one has the capacity to
pump 20 MGD and the other 27 MGD respectively. In conjunction to these two
pump stations there is one pump station with capacity of 21 MGD to remove
treated flows from the plant in the event of high river levels preventing normal
gravity flow discharge. Also, a storm water pump station has been installed. This
station intercepts site runoff, an unnecessary treatment load and potential site
flooding condition, and removes it before entry to the plant. It has the capacity
to pump 11.5 MGD. Various other pumps and mixers are located throughout the
plant for process control.
The performance of the system in 2016 was good. There were no permit violations or
monitoring and reporting violations. The District's Fat, Oil, and Grease (FOG)
Program continued to inspect area restaurants and food preparation facilities.
Public education aspects of the program continued as well. There were no Sanitary
Sewer Overflows (SSO) attributed to FOG during 2016. There were no notices of
violation, but eleven notices to correct were sent to food preparation facilities in
2016. All notices to correct were addressed in a timely manner. The District
contracted with USDA wildlife services for beaver removal near its Chockoyotte
Creek interceptor. Over the course of 2016, there were 30 beavers removed along
with 5 muskrats, 3 otters, and 11 manual dams.
Over the course of 2016, the Roanoke River Wastewater Plant operated very
efficiently. There were no permit violations or monitoring and reporting
violations. The plant flows ranged from a daily maximum of 17.3 Million Gallons
per Day(MGD) to a minimum of 1.8 MGD. The average daily flow was 3.6 MGD.
The plant treated 1,323,420,000 gallons of wastewater throughout the year;
which was discharged to the Roanoke River. There was a yearly average CBOD of
5.2mg/L which ranged from a max of 11.8mg/L to a min of 2.3mg/L with an
average of 97.3% removal. There was a yearly average TSS of 17.4mg/L which
ranged from a max of 55.6mg/L to a min of 7.6mg/L with an average of 90.6%
Secondary clarification removes solids from the activated solids process. Here,
solids in the presence of oxygen, pH control, and mixing, accumulate in excess.
They are removed, chemically stabilized, and added to a holding facility. All
stabilized solids are analyzed and land applied according to their nutrient value,
ceiling and accumulative requirements.
There was an estimated total of 145,450 gallons spilled in SSO's in 2016.

removal. The annual geometric mean for fecal coliform was 6 colonies/lOOmL
which ranged from a max of 670 colonies/lOOmL to a min of 1 colony/lOOmL. The
annual average for Ammonia N was <3.3mg/L which ranged from a max of
11.5mg/L to a min of 0.5mg/L. The annual average for Total N was <13.88mg/L
with a max of <23.64mg/L and a min of 6.53mg/L and the annual average for Total
P was 0.85mg/L with a max of 1.29mg/L and a min of 0.47mg/L.
Roanoke Rapids Sanitary District
2016 Annual Performance Report
The Permit for the Land Application Program was renewed in 2016. During the
renewal, 273.3 acres of land were removed from the permit and 1,053.05 acres
were added, giving a total of 1985.46 acres of applicable land in the current
permit. During 2016 there were 2,888,538 gallons, or 595.35 dry tons of biosolids
applied to 371.76 acres. There were no permit violations for the land application
program in 2016.

Roanoke Rapids Sanitary District
2016 Annual Performance Report
The District has secured contracts with Step Construction to repair and replace
parts of Outfall G and with Herrin-Rivenbark, Inc. to find and fix l&l problems on
Sub-basins C & D, together encompassing the area from Marshall Street to
Madison street, and from Julian Allsbrook Hwy. to Kapstone Paper Mill.

1. C.S.: N/A
2. WWTP: There was one plant bypass, which was reported as required, that
began on October 8, 2016 and ended on October 9, 2016 as a result of heavy
rainfall attributed to Hurricane Mathew. During the period of heavy flows, plant
staff was able to equalize approximately 7,589,462 gallons of influent flow to the
equalizations basins and to the trickling filters for biological treatment. The bypass
occurred at two locations within the plant; the influent pump station overflow,
and the filter recirculation pump station overflow. There were approximately
3,150,576 gallons of water that had preliminary treatment that bypassed at the
influent pump station. There were approximately 2,356,200 gallons of water that
had biological treatment that bypassed at the filter recirculation pump station.
Samples were taken of the bypasses and analyzed. The TSS of the IPS bypass was
43.0 mg/L with a COD of 131mg/L. The TSS of the FRPS bypass was 37.5mg/L with
a COD of 113.5mg/L and a CBOD of >26.1mg/L.
1. C.S.: Along with the wildlife control measure mentioned above, RRSD continues
to perform preventative backup maintenance by cleaning with Jetter and Root
Cutter; which is attached to the Jetter hose, followed by Closed Circuit TV (CCTV)
camera to inspect the lines after cleaning. The District also uses its Vac-con Truck,
which cleans the line more effectively and proves to be more reliable than the old
unit.

All efforts were made to minimize the bypass with flow equalization. 582,658 gallons of wastewater were
bypassed to the equalization tanks. The electrical malfunction of pumps #3 and #4 have been evaluated.
Pump #4 has a motor that went bad. Pump #3 had a vfd fault, probably due to the voltage change caused by
the number 4 pump tripping its breaker. The check valve spring on pump #4 also broke, leaving the check
valve open, allowing some flow to return to the wetwell. Once the VFD on #3 was reset and the check valve
on #4 was’closed, the bypass was over and the pump station returned to normal operation. Efforts are
underway to repair the spring and the motor.
