Nearly 65,000 gallons of sewage spilled into a tributary of Walnut Creek on Monday after paper products clogged a sewer line, according to the Raleigh Public Utilities Department.
City officials estimate the sewage had been spilling for about 3 days off Diggs Drive, near the Lake Wheeler interchange with Interstate 40, before it was reported at noon Monday. City staff had the spill stopped by 1 p.m.
Cleanup work, including clearing the 8-inch pipe, was done by 4:30 p.m., city officials say. They say the spill did not result in a fish kill.
Raleigh officials say paper products other than toilet paper are a common source of clogged sewer lines, because they don’t disintegrate. The city’s policy is that only water, human waste and toilet tissue are permitted in the sewer system.
