Which is a common sign of a failing septic system?

A common sign of a failing septic system includes slow drains and sewage odor. This indication arises because when a septic system is not functioning properly, effluent does not flow as it should through the pipes or into the soil. Slow drainage often suggests that there is a clog within the system, such as in the pipes or the drain field, which can lead to sewage backing up into the home or surfacing in the yard. Additionally, the presence of sewage odor indicates that waste is not being adequately treated or contained, often pointing to saturated soil, failed septic tanks, or problems in the drainage field.

In contrast, increased wildlife activity could be noticed in various situations and does not directly correlate with septic system performance. Bright green grass in the yard may suggest nutrient-rich effluent is rising to the surface, possibly due to a failing system. While it may appear healthy, it signals an issue rather than an effective system. Frequent tank pumping generally indicates that a homeowner is maintaining their system to prevent failure rather than being a direct sign of a failing septic system.
