The lifespan of a concrete septic tank is about to 40 plus years. Many factors affect the lifespan. When constructed, operated, and maintained properly, a septic system will provide treatment of household waste for decades. Septic tanks are constructed of durable material, yet they can deteriorate or have structural issues. When septic systems fail, it’s usually because of improper maintenance.

Septic Tank Maintenance

It’s ideal to have a visual inspection of your septic tank when you pump it. If you are on an effluent pump, have the basket/screen & pump serviced at the same time as the pumping. A septic system can give you problems because of a blocked pipe or tree roots growing in the drain field. The septic system can have a backup if the system is not working properly. Serious problems can result from a clogged main line or a clogged drain field.

The inspection will also indicate if the septic tank needs to be pumped. Tanks are usually pumped and cleaned of scum every three to five years. That frequency depends on the number of people in the household or facility and the amount and types of solids going into the septic system and using a garbage disposal frequently. For example, it may result in more frequent pumping. Antibacterial cleaning products and bath and body oils can also offset the bacterial balance in the system. It’s best not to assume that everything is working properly for years without an inspection.

Types of Septic Tanks

Depending on the age of your septic system, the tank may be steel, fiberglass, concrete, or plastic. A steel tank can rust and fail in as few as 15 years. Your professional will notice signs of failure during the inspection. Concrete tanks made of high-quality materials have lasted 50-plus years without issue.
