This report is published annually and released to our customers in accordance with the requirements of the North
Carolina Clean Water Act of 1999 and provides information on the Publicly Operated Treatment Works (POTW) and
Collection System operated by Winston-Salem/Forsyth County Utilities (WSFC Utilities). It covers the period of July 1,
2023,through June 30, 2024 (FY24).
WSFC Utilities operates two wastewater treatment plants with a combined treatment capacity of 51 million gallons per
day. The wastewater collection system includes 1,825 miles of sewer lines and 45 lift stations. During the period covered
by this report, a total of 14,255,480,000 (14.2 billion) gallons of wastewater was collected and treated at these facilities.
Following the removal of solids and pollutants, 12,616,180,000 (12.6 billion) gallons of water was discharged into Salem
Creek and the Yadkin River. It is important to note that the treated water returned to these waterways is of a higher
quality by most parameters than the water in the river itself.
WSFC Utilities staff works hard to meet and surpass the mandates of the North Carolina Clean Water Act and the
requirements of the National Pollutant Discharge Elimination System (NPDES) permits.These permits regulate the
operation of the treatment plants, the disposal of biosolids, and the operation and maintenance of our collection
system. Staff attend Collection and Wastewater Treatment Plant (WWTP) Operator schools to improve their skills and
obtain appropriate certification and training in order to uphold these standards.
The two wastewater plants operate under the permits listed in the photo captions above, and the wastewater collection
system operates under NPDES Permit WQCS00003.The treatment and disposal of residual biosolids produced by the
plants is accomplished by anaerobic digestion, followed by processing in a biosolids drying facility at the Archie Elledge
nston-Salem/Forsyth County
Wi Liti
WWTP under Permit WQ0029804.The biosolids dryer facility produced 1,135 dry tons of pelletized biosolids during
''t'es
Water•Wastewater•Solid Waste FY24, which were beneficially applied to farmland. Following a Nov. 9, 2023, incident at the dryer, operations were
halted and 4,445 dry tons of"cake" residuals were hauled to the city-owned and operated Hanes Mill Road Landfill.
The water system has three additional NPDES permits: Swann Water Treatment Plant (WTP) operates under General
wsfcutilities.org Permit NCG590003, Thomas WTP under General Permit NCG590044, and Neilson WTP under Permit NC0086011. All
three water plants operated within compliance of their permit conditions during this performance period.The
treatment process at the water treatment plants generates a Class-A residual that is land-applied under Permit
8 1

NOTICE OF AVAILABILITY
