The average septic tank can last between 15 and 40 years, depending on care and maintenance. As the system reaches the end of its lifespan, septic repairs won’t be enough to ensure an efficient waste removal process. If your septic tank shows any of the signs below, it may be time to replace it. 

When to Replace a Septic Tank

1. Frequent Backups

Backups can often be resolved by routine pumping, but consistently clogged systems may need to be replaced. Tree root intrusion, natural shifts in the earth, and heavy equipment, such as vehicle traffic, can lead to a variety of issues, including blocked lines or cracks in the tank.

Sewage backups can be dangerous and put your family at risk of contamination. If you experience them frequently, contact a professional for a comprehensive inspection of the system.

2. Unusually Green Grass

While lush, green grass is typically desirable, it can indicate a failing septic tank when it's centralized above the drain field. As the tank ages, it becomes less efficient at breaking down waste. As a result, the freshwater that usually seeps into the soil becomes contaminated with effluent, which acts as a fertilizer for your lawn.

Occasionally, a leaking line can result in lush patches that may be treated with septic repairs. However, if the tank itself has failed, it's time to have it replaced. 

3. Foul Odors

Strong odors coming from the septic system are always causes for concern. In most cases, unpleasant smells inside your home occur when the tank is full and the septic gases travel through the drains and toilets.

Odors outside occur when the tank fails and the drain field becomes contaminated with wastewater. Both instances may indicate the need to replace your septic tank.
