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 November 23, 2020 sanitary sewer overflow (SSO),
Incident #202003353, located at 114 Cassell Street in Winston-Salem. The incident was a result
of pipe failure due to severe natural conditions.
On November 23 at 8:00pm, Utilities Field Operations was notified of an SSO on the sewer
outfall at 114 Cassell Street. Heavy rains earlier in the month had eroded the Park Branch creek
bank which caused the sewer main to collapse and break. First responders used a backhoe to
dig around the pipe and make a temporary repair. The crew created a containment berm that
diverted flow back into the pipe. They also installed a temporary section of sewer main and
used fast -set cement to seal the ends of the pipe.
The spill lasted approximately five hours and was resolved by 1:00am the following morning. A
diffuser was deployed for approximately eight hours and the spill area was cleaned following
protocol.
This site has been added to an existing capital project so a more permanent repair can be
completed and the stream bank stabilized. Easements for the new alignment are currently
being acquired and the permanent repair will soon follow.
