What is an indicator of a potential issue in a septic system?

A strong odor in the vicinity of the drainfield is a clear indicator of a potential issue in a septic system. This unpleasant smell typically suggests that sewage or wastewater is not being adequately contained or treated within the system. It may indicate a failure in the septic tank or drainfield, where effluent is leaking, backing up, or not dispersing properly. Odors can arise from over-saturation in the soil or a breakdown of organic materials, both of which compromise the functionality and hygiene of the septic system.

In contrast, normal grass growth over the drainfield suggests that the system is functioning properly, as grass can access the nutrients in the treated effluent and typically thrives in such conditions. Consistent gray water flow might indicate adequate drainage, but it doesn’t necessarily inform about potential issues. Lastly, the absence of standing water near the tank is generally a positive sign that the system is functioning well, as pooling water can suggest blockage or failure.
