Most homes in Atlanta are connected to Public Sewers in which case they do not have septic tanks, however, if the home is determined to have a septic tank, and the seller does not provide documentation from a recent septic tank inspection or clean-out, it is advisable to have the septic tank inspected by a certified septic tank inspection company.  Septic tanks and septic tank leaks can be very costly, so its important for a buyer to know the condition of the septic tank and when it will need to be cleaned out which can also be a costly procedure.
