The most obvious indicator is to look out for the pools of water surrounding the system’s drain field. The problem is there are multiple definitions of a “full” septic tank, and only one way — opening the tank lids — to confirm it.
This can then be determined by exposing the lid (s) of the septic tank and checking to see if the liquid level is normal or overfull.
