What causes a septic system to fail?
There are many ways a system can “fail”. It can be as simple as a clogged pipe or burnt-out pump, or as major as a plugged filter or clogged drainfield which needs to be replaced. As you can imagine, the water in your system is full of organic matter. Over time, this organic matter can plug the pores in the soil (or pre-treatment filter) causing it to no longer absorb water. A residence which generates a larger than normal volume of waste or a waste which is stronger than typical for a residence will likely have a pre-mature system failure. There are many other factors which can play a role in system failure.
