Description of Collection System and Treatment Process
The City of Graham operates a Public Owned Treatment Works consisting of a
North Carolina Grade II Collection System and a North Carolina Grade IV
Wastewater Treatment Plant.
The collection system operates under a North Carolina Division of Water
Quality Collection System Permit and contains approximately 89 miles of piping and
seven lift stations. The lift stations are named Back Creek No. 1, Back Creek No. 2,
Boyd Creek, Cherry Lane, Haw River, Old Fields, and Prytle Drive.
The wastewater treatment facility has a permitted flow of 3.5 million gallons
per day (MGD). This facility consists of bar screens, grit collectors, primary
clarification, extended aeration, final clarifiers, sand filtration, chlorination, post
chlorination basin, de -chlorination, digestion, lime stabilization, sludge disposal, and
laboratory. Effluent is discharged to the Haw River designated as Nutrient Sensitive
Waters (NSW), which is part of the Cape Fear River Basin.

Performance
Text Summary of the System Performance for the Period of July 1, 2017 to June 30,
2018.
Collection System: The City of Graham collection system is a combination of
gravity and forced mains. The city is proactive in monitoring and utilizing various
methods to maintain the wastewater collection system. An education program is in
place to inform water customers about the impact of improper disposal of Fats, Oils
and Grease (FOG). Over 10% of the collection system is hydraulically cleaned
annually. Chemical treatment, closed circuit inspection and rehab projects are just a
few methods we implement to reduce and eliminate service outages and overflows.
During the past fiscal year the collection experienced four reportable wastewater
overflows.
Lift Stations: The City of Graham operates seven lift stations that are maintained by
plant maintenance personnel. During this reporting period, the lift stations had two
reportable sewer overflows.
Wastewater Treatment Plant: The City of Graham Wastewater Treatment Plant's
permit has limits on Flow, Biological Oxygen Demand, Total Suspended Solids,
Ammonia, Dissolved Oxygen, Fecal Coliform, Chronic Toxicity, and Total
Phosphorus. Additional testing is performed for Total Residual Chlorine,
Temperature, Conductivity, Copper, Mercury, and Zinc. Each month this data is
reported to the state thru the Discharge Monitoring Report (DMR). The City is a
member of The Upper Cape Fear River Basin Dischargers Coalition that performs
monitoring upstream and downstream of our discharge point on the Haw River as
well as other locations on the Haw and Deep Rivers. The Wastewater Treatment
Plant had one violation of its NPDES permit.
Non -Discharge Permit: The City of Graham land applies biosolids to agricultural
land under regulations of the Environmental Protection Agency and the State of
North Carolina. The City of Graham had one violation in the past year.
Violations of permit conditions or other environmental regulations
relating to water quality from the above areas
October 2017. Residuals runoff, City of Graham farm: Residuals migrated from
an application site into a nearby drainage ditch. The "runoff' event was due to the
exceedance of the hydraulic loading of water treatment plant residuals by Synagro at
the City's Land Application site. Failure to properly notify the WSRO prior to the
application event and following the runoff event were also cited. Residuals were
removed from the drainage ditch after discovery and preventive measures were
taken to prevent future occurrences.
2

January, 2018. NPDES Permit: The Wastewater Plant had a Notice of Deficiency
for monthly Ammonia average. The limit is a monthly average of 8.0 milligrams per
liter (mg/L) of effluent. The City's average for the month of January, 2018 was 13.09
mg/L. Within one week, adjustments to surface aerator run times brought ammonia
readings back in compliance.
February 25, 2018. Sewer Overflow: A reportable sewer overflow of 13,140 gallons
of untreated sewage spilled into "Bowden Branch" and entered the Cape Fear River
Basin." The spill was the result of debris in a sewer pipe. The blockage was cleared
and service was restored.
April 16, 2018. Sewer Overflow: A reportable sewer overflow of 2,000 gallons of
untreated sewage spilled into "Town Branch" and entered the Cape Fear River Basin.
The spill was the result of root intrusion in pipe. Blockage was cleared and service
was restored.
April 24, 2018. Sewer Overflow, Boyd Creek Liftstation: A reportable sewer
overflow of 2,200 gallons of untreated sewage from the Boyd Creek Liftstation spilled
into "Bowden Branch" and entered the Cape Fear River Basin. The spill was caused
by Inflow and Infiltration from heavy rain in the area. All equipment and alarms
worked properly.
May 8, 2018. Sewer Overflow: A reportable sewer overflow of 2,000 gallons of
untreated sewage spilled into "Town Branch" and entered the Cape Fear River Basin.
The spill was the result of root intrusion in pipe. Blockage was cleared and service
was restored.
May 18, 2018. Sewer Overflow, Boyd Creek Liftstation: A reportable sewer
overflow of 5,460 gallons of untreated sewage from the Boyd Creek Liftstation spilled
into "Bowden Branch" and entered the Cape Fear River Basin. The spill was due to
local heavy rain in the area. The Waste Water Treatment Plant recorded
approximately 1.25 inches of rainfall however the liftstation area is believed to have
received more. All equipment and alarms worked properly.
June 20, 2018. Sewer Overflow: A reportable sewer overflow of 2,000 gallons of
untreated sewage spilled into "County Home Branch" and entered the Cape Fear
River Basin." The spill was the result of debris in a sewer pipe. The blockage was
cleared and service was restored.
SUMMARY
During this 12 -month period, there were one NPDES permit violations out of
more than 2,400 sample results.
The City of Graham had six reportable sanitary sewer overflows of 1,000
gallons or more during this reporting period. The total gallons of overflow were
26,800.
3

Total gallons handled by the system were 655,060,000. Percent gallons
overflowed are 26,800 divided by 655,060,000 x 100 = 0.004 %. Therefore, the City
of Graham achieved a 99.996 % collection rate of all gallons discharged into the
system, excluding any spills that were less than 1,000 gallons.
All sludge was land applied per Land Application Permit regulations with one
permit violation.
