How do I know if my septic system is failing?

Wondering if you have septic system problems? Here are some telltale signs that you may require maintenance:

1. Sewage backs up into the house via drains.
2. A smell of sewage outside the house near the septic tank or around the field lines, especially if this smell is more noticeable after a lot of water has been put into the system, like when there are multiple showers taken or several loads of laundry done in a small amount of time (if the laundry water discharges into the septic system).
3. A “spongy” feeling in the lawn above the drain field or near the septic tank. The “spongy” feel may be caused by water and waste being pushed to or near the ground surface.
4. Standing water (called breakthrough) is noticeable in the lawn above the tank or drain field.
5. A patch of bright green grass over the drain field in the winter, or lush green growth in the summer when other grasses are slow-growing.
6. Buildup of aquatic weeds or algae in streams or ponds adjacent to your property.
7. Gurgling sounds in your pipes or drains.
