What are some signs of potential septic system failure?

Unpleasant odors and wet spots in the yard are clear indicators of potential septic system failure. When a septic system is functioning correctly, waste is processed and absorbed into the soil. However, if there are odors or pooling of water in certain areas, it suggests that the system is not properly diverting wastewater, possibly due to a clogged or damaged drain field. This can lead to backups and may require urgent attention to prevent further damage to the system and the surrounding environment.

In contrast, strong sunlight and dry soil typically indicate favorable drainage conditions, which would not signal a malfunction. Overflowing rain gutters relate to surface water management rather than septic system health and do not indicate issues with the septic system itself. Crisp and green grass could be attributed to healthy soil conditions, rather than being a sign of septic system failure. In this context, these other choices do not represent the critical signs that would suggest a failing septic system.
