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

The presence of water near the drain field is a common indication that a septic system may be failing because it signals that the system is not properly processing and dispersing wastewater. A functioning septic system should have the capability to absorb and treat wastewater effectively, preventing accumulation on the surface. When water is visibly pooling in the area surrounding the drain field, it suggests that the soil is saturated, the drainage is inadequate, or there is a blockage in the pipes. This situation can lead to groundwater contamination and unpleasant odors, making it a clear sign of a potential failure within the system.

Regular evaporation from the tank is not typically an indicator of failure; instead, it describes a normal process that occurs in a healthy system. Healthy plant growth above the system can occur even if the system is functioning properly, as roots may thrive on nutrients from the wastewater, rather than indicating a problem. Reduced water usage in the household would not suggest a failing septic system; in fact, it may suggest the opposite, as decreased water input can alleviate stress on the system.
