An estimated 38,400 gallons of sewage spilled from a clogged pipe near a subdivision off West Garner Road on Monday, according to the Raleigh Public Utilities Department.
The clog was caused by paper products that had built up in the 8-inch diameter pipe near Cranston Road in the Cloverdale subdivision, according to the city. It estimates that the overflow had been going on for about 24 hours before it was reported at 3:50 p.m.
About 10,000 gallons of the spilled sewage reached an unnamed tributary of Big Branch South, according to the city. The spill was controlled by 5:30 p.m., and the city said it would have the area cleaned up by 3 p.m. Tuesday.
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.
Raleigh provides water and sewage services to several Wake County towns, including Garner.
