Georgia requires septic system installers and pumpers to be certified and listed with the Department of Public Health. County environmental health offices issue permits for new systems, repairs, and replacements — pulling a permit protects you at resale and keeps the county's records straight. If you're buying a home with a septic system in Cobb County, ask for the permit history and get an inspection before closing.
