DURHAM, N.C. (WNCN) — Durham city officials say more than 575,000 gallons of raw sewage have flowed into the Eno River during an overflow and leak that has not been repaired.

The incident was reported around 2:30 p.m. Saturday within West Point Park, according to a news release from the city of Durham.

Officials said that “all the manholes in the area” overflowed because of several days of rain.

The news release said recent rains caused the Eno River to flow at six times its average for this time of year.

Pressure from the overflowing manholes created a leak in a sewer line and 576,000 gallons of sewage flowed into the river, the news release said.

“Due to the conditions of (the) surrounding area, the repairs cannot begin until the water levels drop,” authorities said in the news release.

The North Carolina Department of Environmental Quality Division of Water Resources was notified of the incident Sunday.

Durham officials said there are no “immediately visible” adverse environmental impacts or hazards.
