A system that is used conservatively and maintained regularly by pumping the septic tank can last a very long time if it was originally installed correctly. The best systems are shallow systems which allow air to enter the soil and penetrate to the vicinity of wastewater absorption.
Studies that just look at averages without regard to quality of construction or how the system is utilized show that the average life of a septic system is 20 years or more. This is the time period until the system becomes sufficiently clogged with organic material that it either results in effluent coming to the soil surface or backing up in the plumbing and reducing the efficiency of flow from the home.
Well constructed, well maintained systems will last longer.
