General Information: Facility/System Name: Town of Stantonsburg Wastewater Treatment Plant 86 Collection System Responsible Entity: Town of Stantonsburg, N.C. Wilson County Contacts: Roger E. Sullivan, ORC Town of Stantonsburg P.O. Box 10 Stantonsburg, N.C. 27883 Phone-(252)-238-2679 David R. Beaman, Administrative Officer Town of Stantonsburg P.O. Box 10 Stantonsburg, N.C. 27883 Phone-(252)-238-3608 Applicable Permits: NPDES Permit No. NC0057606 Collections System Permit No. WQCS00213 Description of Collection System &Treatment Process: The Town of Stantonsburg wastewater collection system consists of approximately 10.5 miles of sewer pipe which flows to the Town's lift stations, or travels by means of gravity through said sewer pipe to the wastewater treatment facility located just off of Peacock Bridge Road. This wastewater treatment facility has a permitted discharge rating of.375-million-gallon daily average and treats by mean of a draft tube extended aerobic oxidation ditch, a separate secondary clarifier, aerobic digester, and UV disinfection. The wastewater treatment is rated as Grade II treatment facility, and discharges treated wastewater into nearby Contentnea Creek. The wastewater treatment plant also produces residuals or a sludge by-product that is land applied at Granville Farms, Inc.'s permitted facility. The Town completed construction of its Wastewater Treatment Improvements Project Phase I in the fall of 2014. This project consisted of the construction of a mechanical bar screen, a secondary, clarifier, a sludge pumping station, an intermediate pumping station, an effluent parshall flume for flow measurement, and ultraviolet disinfection system, a cascade post aeration and installation of electrical generator. The Town also received and treated the Town of Saratoga's wastewater which stopped at the end of July 2021, as the Saratoga began sending their wastewater to the City of Wilson. II. Performance: Text Summary of System Performance for the Fiscal Year 2021-2022: The Town's wastewater collection system encountered relatively few problems during the fiscal year ending June 30, 2022, with the exception of exception of July 2021 and the first half of August 2021 with excessive flows. This was due the continued well above average rainfall from the first half of 2021 that plagued the area and continued until the first half of August 2021. After August, the area began a drying trend. This trend has continued throughout the rest of the fiscal year. At the time of this report, Wilson County is classified as in an extreme drought. Although, with the excessive flows in July and August 2021, the collection system experienced no known or reported spills. The Town had an expansion of the sewer system which extended 3,805 linear feet of 8-inch sewer main to a new 41 lot sub-division on Sand Pit Rd. The Town was awarded an intent to fund from the State Revolving Fund Section for a$1,387,776.00 sewer rehab loan. Currently the Town is pursuing additional funding to assist with this loan amount and help to maintain our debt service at manageable levels. This funding will allow the Town of Stantonsburg to continue to address Inflow and Infiltration issues of the collection system. Importantly, the Town's wastewater treatment plant experienced relatively few problems with the exception of the excessive flows with the continued well above average rainfall from the first half of 2021 that plagued the area and continued until the first half of August 2021. As stated above, a drying trend begun and continues as of the date of this report. At the end of fiscal year 2021-2022, Wilson County is categorized as in "Extreme Drought". With these continued dry conditions and no longer treating the Town of Saratoga's wastewater, the Stantonsburg WWTP was compliant throughout the fiscal year and continues to operate well below its permitted capacity. No major mechanical failures occurred, and normal and routine maintenance was performed by town staff. Unfortunately, in calendar year 2020, our area had 73+/- inches of rainfall. This is nearly twice the average rainfall for Wilson County. This caused the Town of Stantonsburg WWTP to operate at 83% of it's daily average permitted capacity. In May 2021 the Town was notified from NCDEQ that is would be placed on a Sewer Moratorium due to being over 80% capacity for calendar year 2020. This Sewer Moratorium was lifted and the end of 2021 after it was shown that 2020 was an abnormally wet year and that the Town of Saratoga contributed to as much as 25% of flow in 2020.
