Two septic tanks in the ground.

Your septic tank is, without a doubt, one of the most vital components of your home’s plumbing system. It’s responsible for treating and removing wastewater, which means it’s crucial to keep it functioning properly. But, have you ever paused and asked yourself: “How long does a septic tank last?” There’s no need to wonder any longer. Below, we will walk through everything you need to know about septic tank lifespans.

What Is the Average Septic Tank Lifespan?

The average lifespan of a septic tank is roughly 25 to 30 years. However, with proper care and maintenance, septic tanks can last much longer. Regular maintenance is absolutely key to ensuring that your septic system stays in tip-top shape. One of the most critical aspects of septic tank maintenance is to pump your tank regularly. The frequency of pumping will largely depend on the size of your tank and the number of residents in your home. Generally speaking, your septic tank should be pumped every two years.

So, how long does a septic tank last with maintenance? Although there isn’t really a straightforward answer to this question, it’s important to know that neglecting your septic system can potentially lead to costly repairs or even a complete septic tank replacement. Fortunately, a professional can inspect your tank and leach field and make sure that everything is working as it should.

Soil Types

The type of soil on your property can also have an effect on your septic tank lifespans. If you have sandy soil, for instance, your tank is more likely to last longer than if you have clay soil. Sandy soil is better for drainage and allows the bacteria in your septic tank to break down waste more efficiently.

Tank Types

Steel septic tanks are less durable than other materials, such as concrete or fiberglass. If you have a steel septic tank, you can typically expect it to last around 15 to 20 years with proper care and maintenance. Steel tanks are also more susceptible to rust and corrosion, particularly in areas with high levels of rainfall or near bodies of water.

All-in-all, concrete tanks are the most durable option. So, how long does a septic tank last if they’re made out of concrete? Simply put, they last up to 40 years with proper care and maintenance. Concrete septic tanks are also resistant to rust and corrosion, making them a perfect option for areas with high levels of rainfall or near bodies of water.

Water Table

The water table on your property can also have an impact on your septic tank lifespans. If your water table is high, it can cause problems for your septic tank. High water levels can prevent your system from draining properly, which can lead to backups and other issues. If you happen to live in a place with a high water table, it’s essential to have your septic tank inspected regularly to ensure that it’s working properly.
