BRUNSWICK COUNTY — Brunswick Regional Water and Sewer (H2GO) reported a host of system overflow events that affected Brunswick County on Friday, May 19.
According to H2GO, “Collections personnel discovered the overflow while responding to a lift station high-level alarm.”
Roughly 13,500 gallons of untreated wastewater flowed from a manhole on Lanvale Road in Leland to a drainage feature at a tributary of Surgeon Creek. The manhole was roughly 180 feet south of King Road.
Friday’s significant rainfall contributed, as there are numerous manholes in the collection system tributary to the North Lanvale lift station and the Belville WWTP submerged in water, H2GO reports.
Belville WWTP, located at 9911 Chappell Loop Rd., had 108,000 gallons of partially treated wastewater discharged into the Brunswick River; a bypass of 10,000 gallons of partially treated effluent was contained to the treatment plant site.
The effluent pumps at Belville WWTP became air-locked. Failing air release valves installed on the line had become waterlogged.
The bypass of partially treated wastewater at the Belville WWTP occurred from excess inflow of stormwater into the collections system. H2GO determined construction of development sites nearby contributed to the temporary sewer plugs failing.
The overflow has been reported to the NCDEQ office.
