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. 1 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.
