What are the symptoms of a failing septic system?

The major symptom of a failing septic system is slow drains in all the bathrooms. Wastewater will sometimes come up in the lowest fixtures such as the shower or tub. Another common symptom is a foul odor in the yard near the septic system or standing sewage on top of the ground. This is not normal, drains should flow freely, no odors or sewage should be noticed.
