What is a common sign that a septic tank is taking on water?

A high water level in a septic tank can indicate that the tank is taking on water, which may be a result of groundwater infiltration or heavy rainfall. When the soil surrounding the septic system becomes saturated, it can lead to an excess of water entering the tank, causing the water level to rise.

Monitoring the water level in a septic tank is crucial for proper maintenance. A consistently high water level often suggests that the system is not functioning as intended, potentially leading to sewage overflow or backflow issues. In contrast, a low water level might indicate normal operation, while foul odors typically relate to a breakdown in the system rather than excess water. Soaking wet ground is a symptom of a failing system, but does not directly reflect the water level within the tank itself.
