Reported to DeKalb Watershed Management, 770-270-6243, previously. After report, a sign saying "Private Sewer Spill" appeared, I suppose posted by DeKalb. May need to report to the property owner or management company.

Don't know if it's the city's or the county's responsibility to enforce, but it is a public health hazard and the leak is draining into the city stormwater system and eventually polluting the Peavine Creek tributary on West Ponce.
