What is a common sign that a septic system may be failing?

A common sign that a septic system may be failing is the presence of odors near the septic area. When a septic system functions properly, it should effectively treat and contain waste, preventing any unpleasant smells from escaping. However, if odors are noticeable, it may indicate that the system is not processing waste correctly, possibly due to issues like clogs, overloading, or a broken component. This situation can lead to environmental hazards and health risks, highlighting the necessity for immediate attention to prevent further failure.

In contrast, a well-drained lawn would typically indicate good drainage and a functioning system, while frequent visits to the tank might not necessarily signify failure, as some systems require regular maintenance. Clear discharge into a stream could suggest a serious problem with contamination and leakage but does not directly indicate a system failure. Thus, the presence of odors is a clear and actionable sign that the septic system needs to be evaluated.
