Incident # 202300288-On Monday, February 13, at approximately 1 PM, the Water Infrastructure
division became aware of a sanitary sewer overflow at manhole #4238 on the Bloomery outfall. The
previous weekend, heavy rains in the area and west of our county caused the banks of Contentnea
Creek to overflow. As a result, the outfall line flooded, and caused inflow and infiltration on the sewer
line. At approximately 2 PM on Tuesday, February 14, the waters of the creek receded and the SSO
stopped.
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 is now underway,
(which includes the area where this SSO occurred), with an estimated cost of $3,583,752.90.
Construction for this phase should be completed in 1 year.
An estimated 63,000 gallons was spilled and did reach surface waters.
I can be reached at [phone] with further questions.
Sincerely,
L. Aaron Bailey
Division and Maintenance Superintendent
