What started as a simple fence job in Hillsborough turned into a messy weekend problem, after a fence post punctured an 8‑inch sewer main and sent roughly 38,400 gallons of untreated wastewater into a drainage ditch near Odie Street, according to town officials. The spill flowed from a sewer cleanout into a roadside ditch that feeds an intermittent tributary and then Bellevue Branch. Town staff say the Eno River does not appear to have been affected. Utilities crews followed their noses late Saturday, traced the odor to the break, and stopped the leak on Monday morning.
In a news release, the Town of Hillsborough said the trouble started when a fence post became lodged in an 8‑inch sewer main on Daye Street, letting wastewater escape at a cleanout near 219 Odie Street. The town pegged the volume at about 38,400 gallons and said the Raleigh Regional Office of the Division of Water Resources was verbally notified and will receive a written report. Local television coverage echoed the town’s account and reported that crews ultimately located and halted the discharge on Monday morning, according to CBS17.
Hillsborough’s sewer system has been under pressure since Tropical Storm Chantal in July 2025, when floodwaters swamped pump stations and triggered several overflows into the Eno River and nearby creeks, along with emergency actions and boil‑water advisories. WRAL reported on those impacts last year. Even before this latest mishap, local partners were already installing green‑infrastructure projects on Odie Street, including bioswales designed to slow runoff and filter pollutants before they reach streams, work described by Chapelboro.
State reporting rules
N.C. law requires utilities to report and publicly disclose untreated wastewater discharges. A news release is required when 1,000 gallons or more reaches surface waters, and for spills of 15,000 gallons or more, a state‑approved public notice must be published. Those thresholds are laid out in N.C. General Statute 143‑215.1C. In this case, the town says the Raleigh regional office of the Division of Water Resources has been notified and will receive a written follow‑up report.
What residents should watch for
Town officials say the spill is not believed to have reached the Eno River, but residents are urged to steer clear of any discolored or foul‑smelling creeks and to report sewage odors, backups, or other sanitation problems to the utilities department. Local outlets such as CBS17 are expected to carry follow‑up coverage, and residents can also sign up for the town’s emergency alerts for official updates and guidance.
