This letter serves as the official response from Winston-Salem/Forsyth County Utilities to the
North Carolina Department of Environmental Quality, Division of Water Resources Notice of
Intent to Enforce Civil Penalty for the March 17, 2022 sanitary sewer overflow (SSO), Incident
#202200417, located at 3261 Robinhood Road in Winston-Salem. The incident was a result of
debris in the line.
On March 17, 2022 at 10:19am, an SSO occurred at 3261 Robinhood Road in Winston-Salem.
Our first responders determined an accumulation of debris had caused the overflow. They
discovered a large amount of wipes and used a jet -vac truck to remove the blockage. The
problem was resolved within 45 minutes and normal flow was restored by noon the same day.
The area was cleaned following standard protocol and a diffuser was deployed for five hours.
Upstream and downstream mains were cleaned and inspected by CCTV with no visual defects
observed.
WSFC Utilities continues to make progress in minimizing SSOs and has the proper programs in
place to continue our high level of performance. Outreach with the No Wipes in Pipes campaign
continues to educate the public on proper disposal of all wipes. cityofws.org/nowipes
Additionally, our comprehensive sanitary sewer evaluation study has provided strategic
cleaning and examination of our system to identify areas with the greatest need for repair and
replacement. While we are required to clean 10% of the system each year, in FY 2020-2021,

WSFC Utilities cleaned more than 330 miles. This is 19% of the 1,783-mile gravity wastewater
collection system and 228 of those miles (69%) were proactively cleaned by in-house and
contracted crews. Our ongoing internal goal is to clean at least 20% of the entire gravity
collection system, with more frequent cleaning systematically scheduled for areas with higher
incident levels.
I hope this information is helpful with your investigation of Incident #202200417. If you require
additional information, please contact me at 336-747-7315.
