How do septic systems fail?
Septic systems are simple in nature but are very complex and robust treatment mechanisms. A properly designed, installed and maintained system can yield decades of service life. However like any system it has a finite life and will eventually need to be replaced just like your car or roof of your home. Septic systems are not immune to abuse or neglect, so the system can prematurely fail if abused. There are several causes for failure (as described below) but in a majority of these cases the system can be overloaded and an overly restrictive biomat formation can occur in the leachfield. When this occurs water enters the system at a greater rate than it can be absorbed causing the system to back up.
