PITTSBORO — Chatham County Public Utilities reported untreated wastewater discharge in Harlands Creek last week, but minimal damage is expected, officials say.
The discharge was reported last Thursday morning (June 23).
"County staff discovered the discharge at a manhole located along NC 64 Highway," Chatham County Utilities said in a statement. "Approximately 800 feet east of Renaissance Drive in Pittsboro."
Utilities officials said the discharge was about 2,000 gallons, but the damage was minimized later that morning. Officials told the News + Record the pipe has since been completely repaired.
"The cause of the discharge was due to a pipe failure inside the manhole that overflowed," Utilities officials said. "Utilities crews immediately worked to repair the pipe and remediate the spill. The untreated wastewater from this pipe failure discharged into an unnamed tributary of Harlands Creek."
Harlands Creek is a more than 10 mile long tributary outside of Pittsboro that flows south to the Rocky River.
Previously, Chatham County has had one other sanitary sewer overflow into a tributary of Harlands Creek on September 11, 2020. That discharge was about 3,000 gallons and was also caused by pipe failure inside a manhole.
"The potential impact of this sewage discharge of 2,160 gallons to Harlands Creek is very minimal considering the low volume," Chatham County Utilities Director Blake Mills told the News + Record. "The discharge was not directly into Harlands Creek it was through the top of the manhole which entered a dry ditch that has to travel at least 1,200 feet to get to a tributary of Harlands Creek."
Mills said the impact is measured using the number of gallons of sewage that could potentially reach Harlands Creek as a result of the sanitary sewer overflow.
He said when utilities services found the overflow, it was immediately blocked with dirt.
"[We] used a vacuum pump to remove the standing water, removed from the site dirt that was exposed to the sewage and spread lime on the impacted areas which will act to neutralize the sewage," Mills said.
The NC Department of Environmental Quality’s Division of Water Quality Raleigh Regional Office was notified of the event within the 24-hour requirement. For more information, please contact Chatham County Utilities Director Blake Mills at 919-542-8238.
