Re: Sanitary Sewer Overflow Civil Penalties Incident #202200666

This letter serves as the official response from Winston-Salem/Forsyth County Utilities to the Notice of Intent to
Enforce Civil Penalty for the sanitary sewer overflow (SSO) Incident #202200666 caused by mechanical failure of
a flapper valve on the outgoing pipe.
On April 20 at 8 p.m. an SSO occurred behind 4448 Winterberry Ridge Court in Winston-Salem. Our first
responders determined a flapper valve on the 8-inch sewer main had failed. They opened the flap and normal
flow was restored within eight hours at 4 a.m. on April 21. The area was cleaned following standard protocol and
a diffuser was deployed for six 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 maintain
our high level of performance. Since the start of the Collection System Improvement Program in 2016, we have
cleaned 58% of our system, which is more than 1,000 miles of pipe. We are well positioned to exceed our goal of
cleaning the entire system by 2026.
I hope this information is helpful with your investigation of Incident #202200666. If you require additional
information, please contact me at 336-747-7315.
Nceely,
Courtney river, P.E.
