Regional C:
This letter is in response to the Notice of Violation and Recommendation for Enforcement Letter
dated July 11, 2022 received by the City of Greensboro. The address where the violation
occurred and the amount spilled is shown below:
1. 1809 Dellwood Avenue 2100 Gallons
The sanitary sewer release at 1809 Dellwood Avenue on May 4, 2022, was due to debris
accumulation in the sanitary sewer at this address. A combination jet truck was dispatched to
unstop the blockage and clean the line. Once the sanitary sewer overflow was stopped, we
thoroughly cleaned all lines in the area to ensure we could perform a CCTV inspection of the
line to see if further action would need to be taken to prevent future debris accumulation. Upon
our CCTV inspection, we found a heavy presence of "flushable wipes" that the residents are
using. To combat this current trend, we produced and distributed public notices via social media
and television on the effects that wipes have on the collections system to help prevent future
accumulation. We also found bricks and rocks that lead to the long duration time of the event due
to them being difficult to remove. The line is currently on a biannual PM schedule, and we will
monitor the line to see if that cycle needs to be increased in the future.
Remediation efforts include opening fire hydrants to flush the affected area.
It is our duty to comply with the requirements of Collection System Permit Number WQCS00006
and G.S. 143-215.1(a)(1), and we will continue to address unforeseen circumstances as quickly
as they occur. If any additional information is required, please do contact me. We appreciate
your review and welcome your feedback.
Sincerely yours, -�
Robert Martin, Construction and Maintenance Supervisor
