Did you know that 25% of Americans use septic tanks? 

Most communities use a septic system to handle this excess waste. A septic system is far more efficient and cost-effective than what you’d find in most municipal sewage treatment facilities.

Read on to learn more about how long does a septic system last.

The Average Lifespan of a Septic System

Most septic systems have an average lifespan of 20-30 years. However, this can vary greatly depending on several factors and how long does a septic system last, such as the type of septic system, the maintenance routine, the soil type, the water table, the climate, and the loading on the system.

A well-maintained system in sandy soil with a low water table and light loading will last longer than a system that is not maintained and is subject to a high water table and heavy loading.

Factors That Affect the Septic System

Several factors can affect the lifespan of a septic system and shorten its overall life expectancy. These include the type of soil present, the groundwater level, the amount and type of wastewater produced, the frequency of septic tank pumping, and the septic system maintenance/upkeep of the system.

In general, systems that are adequately maintained and pumped regularly will last longer than those that are not. Systems that are designed and installed correctly will also tend to last longer than those that are not.

Signs That Your Septic System Is End of Its Lifespan

One sign that your septic system may be nearing the end of its lifespan is if you start to notice sewage backup. This can signify that the septic tank is full and needs to be pumped. If you see sewage backup, you must contact a professional to inspect your septic system.

Another sign that may be nearing the end of the septic system lifespan is if you notice an increase in the level of sewage in your leach field. This can signify that the leach field is not draining correctly and needs to be replaced. If you notice an increase in the level of sewage in your leach field, it is essential to contact septic inspections services for homes to have your septic system inspected.

When to Replace Your Septic System

A rule of thumb is that most septic systems last 20 to 30 years, but many variables can affect this timeline. Usage, for instance, takes a toll on septic systems. The more people using the system, the sooner it will need to be replaced.

It’s essential to have your septic system regularly inspected to ensure it’s functioning properly and to catch any problems early on. Doing so will extend the life of your system and help you avoid costly repairs or replacements down the road.

Know How Long Does a Septic System Last

The average septic system has a lifespan of 20 to 30 years. However, with proper maintenance, your septic system could last for decades. Contact your local septic professional to develop a maintenance plan for your system and to know more about how long does a septic system last.
