About 17,000 gallons of raw sewage spilled into DeKalb County waterways Tuesday.

County water reports show a 12,000 gallons spilled into the North Fork of Peachtree Creek from the 2300 block of Chamblee-Tucker Road in Chamblee. A 4,980-gallon spill was also reported in Snapfinger Creek from the 4500 block of Birch Ridge Trail in Stone Mountain.

In December, the federal Environmental Protection Agency mandated the county upgrade its sewage system after more than 800 spills were reported in five years.
