Septic systems offer an eco-friendly, economical means of wastewater treatment for homeowners and businesses, particularly those in rural areas without municipal sewer lines. If you’ve recently moved onto a property with a septic system or are considering installing one, there are a few things you need to know. Northern Lights Septic Systems & Excavating in Fairbanks, AK, is the area’s go-to for septic installation and repair. Here, they explain how long you can expect system components to last and what you can do to extend their lifespan. 

What Factors Affect Septic System Lifespan? 

Of the many factors that affect septic system longevity, maintenance is one of the most significant. Tanks that are regularly inspected and pumped last much longer than those that are not. Usage is another significant factor. Conserving water and flushing only biodegradable materials into the tank are two ways to prevent failure or premature replacement. Soil and water conditions can also affect the lifespan of all components, as can the material the system is made of. 

What’s the Average Life Expectancy for System Components? 

The septic system is comprised of several components, some of which tend to last longer than others. The tank is the central unit in the wastewater treatment system and can be made of concrete or steel. Steel tanks rust over time, depending on factors such as soil acidity and the quality of the material and its coating. Typically, these last about 15 years before the rust is significant enough to cause issues. Concrete tanks, on the other hand, can last 40 years to a lifetime, depending on the quality of the material and water acidity. 
 
A well-maintained drain field can last for 50 years or more, although a poorly-installed one may fail within a few days. Other factors that can affect its lifespan include size, usage level, and soil percolation rate. Ask your neighbors how long their drain fields have lasted to get a better idea of when you’ll need to replace it.
