Re: Sanitary Sewer Overflow Civil Penalties Incide <Z02002757
Dear Mr. Snider:
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 October 8, 2020 sanitary sewer overflow (SSO), Incident
#2020027S7, located at 644 Arbor Drive in Winston-Salem. The incident was a result of pipe
failure within the collection system.
On October 8 at 11:07am, Utilities Field Operations was notified of an SSO at 644 Arbor Drive.
There was evidence of sewer and stagnant water in the storm drain. Dye tests were conducted
on the sewer lines, but no dye appeared in the storm drain. First responders were unable to
visually locate the leak.
A CCTV crew responded and quickly inspected the sewer main to find the cause of the pipe
failure. During their investigation, a defect in the pipe was found that allowed wastewater to
leak out of the pipe and into the nearby stormwater system once the level rose above three
inches.
To resolve this issue, permanent repairs were made to the pipe and all leaks were fixed. A six-
foot section of six-inch pipe was also replaced. A diffuser with dechlorination tablets was
deployed for more than 12 hours and the spill area was cleaned following protocol.
