Performance
Text Summary of the System Performance for the Period of July 1, 2019 to June 30,
2020.
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 no reportable wastewater
overflows.
Lift Stations: The City of Graham operates seven lift stations that are maintained by
Collection and Distribution personnel. During this reporting period, the lift stations
had three 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 reportable sewer overflow and no violations 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 no violations in the past year.
Violations of permit conditions or other environmental regulations
relating to water quality from the above areas
October 28, 2019. Digester line overflow: A reportable overflow of 3,000 gallons
(2,800 of which reached Town Branch Creek) untreated sewage spilled near Digester
#2. The spill was the result of a blocked line. The blockage was cleared, damaged
cleanouts were replaced and lime was applied to areas around the spill. All
equipment and alarms worked properly.

January 3, 2020. Sewer Overflow: A reportable sewer overflow of 280 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.
February 6, 2020. Sewer Overflow: A reportable sewer overflow of 49,800 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.
April 13, 2020. Sewer Overflow: A reportable sewer overflow of 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.
SUMMARY
During this 12-month period, there were zero NPDES permit violations out of
more than 2,400 sample results.
The City of Graham had two reportable sanitary sewer overflows of 1,000
gallons or more during this reporting period. The total gallons of overflow were
52,800.
Total gallons handled by the system were 696,120,000. Percent gallons
overflowed are 52,800 divided by 696,120,000 x 100 = 0.008 %. Therefore, the City
of Graham achieved a 99.992 % 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 no
permit violations.
