Incident # 202201252-On Sunday August 7, 2022 at 7:45 AM, the water infrastructure department
became aware of a sanitary sewer overflow on the sewer outfall near 3527 NC Highway 42 W, Wilson,
NC. The cause of the overflow was pipe failure. Crews were dispatched, a temporary bypass was
immediately put into operation and within 45 minutes, the overflow had stopped. Crews then spent
approximately 6 hours cleaning the area by pumping residual sewer back into the system, removing
solids, and spreading lime in the affected area. The cost of repairs and cleanup was approximately
$1,500.
In May of 2022, Phase 1 of the Upper Bloomery Swamp Outfall replacement was completed. The 18-inch
sewer main was upgraded to 24 inch, with an approximate cost of $800,000. Phase 2 has been designed
and funding is secured. Phase 2 is currently out to bid and construction is scheduled to begin at the
beginning of 2023.
An estimated 6,500 gallons was spilled, with none reaching surface waters.
Incident # 202201377- In addition, on August 31, 2022, at approximately 10:00 AM, City crews became
aware of a sanitary sewer overflow at 2115 Lane St. SE, Wilson NC. Upon inspection, crews discovered
that someone had removed the lid from the manhole, threw the lid in the creek and introduced foreign
objects (limbs, rocks, etc.) into the manhole. Within 30 minutes, crews had removed the stoppage using
a flusher truck. Solids and debris where removed from the site, lime spread in affected areas, and the
creek flushed with potable water for the next 6 hours. Absorbent mats were placed downstream of the
incident to prevent further contamination. Fecal coliform samples were collected until acceptable levels
were achieved per the City's SSO response plan. A locking ring and cover was placed on the manhole to
prevent further vandalism. Total cost of cleanup and repair was approximately $2,500.
The City distributes FOG materials to residents' bi annually to educate the public on what should not be
introduced into the sewer system. Crews periodically monitor this area for other issues and perform
maintenance as needed.

An estimated 900 gallons overflowed with 900 gallons also reaching surface waters.
