How Long Will Your Septic Tank Last?

Septic tanks remain a major system in every home, but most homeowners don't pay much attention to them until they develop serious issues. The majority of people frequently believe that septic tanks are made to last forever, but the truth is that they typically only last 15 to 40 years on average. This wide range is due to the fact that the average life depends on a variety of factors, many of which will be discussed in this PDF.

1. How Long Will Your Septic Tank Last?
A septic system can last anywhere from 15 to 40 years on average. Since
numerous factors determine its longevity, these numbers may fluctuate.
Those factors encompass construction material, soil type, maintenance
practices, water table, etc. Also, this lifespan estimate implies that your septic
tank was professionally built and installed by a licensed and experienced
plumber under local building codes.
If you're unsure how many years your septic tank might have left, this article
will provide you with in-depth information to help you estimate. Let’s take a
closer look at the factors that influence the septic tank's lifespan and how you
can make it last longer.
Factors affecting the longevity of the septic tank
Construction Material:
The material type used in the septic tank construction is one of the substantial
factors influencing life expectancy. A septic tank is made of several different

2. materials, each with its own lifespan. But steel and concrete are two of the
most frequent materials utilized to create a septic system.
• Steel: Because of steel's vulnerability to rust, septic tanks built of steel have
the shortest lifespan of 20 years. It is imperative to get your septic tank
inspected periodically to avoid rusting. Moreover, if your steel septic tank is
over ten years old and hasn’t been inspected for a prolonged time, wait no
longer and call the professionals of septic pumping in Roseville .
• Concrete: Concrete-based septic tanks have the longest lifespan of 40
years, amongst other construction materials. It's for a reason why they're
more expensive and sometimes difficult to install. Apart from pipe clogging
and rusting, there are no other factors that can decrease the lifespan of a
concrete septic tank. However, just because it's built of concrete doesn't mean
it won't need to be inspected. It requires inspections to verify that no cracks
have formed and that it is in excellent working condition.
Soil Type:
Another factor affecting the longevity of a septic tank is the acidity of the soil
in which it is buried. It will be difficult for your septic tank to infiltrate and
distribute into the soil if it is hard and clay soil, resulting in clogging and
overflowing. Hence, it is advisable to schedule an inspection as quickly as
possible if your septic tank is surrounded by hard or clay-like soil to prevent an
overflow.
Usage:
The number of people using the septic system creates a significant difference
in its lifespan. However, if you pump your septic tank every three to five years,
it lessens the chances of replacement and helps it to last longer.
Wet sites:
A septic tank placed in a flood-prone region or near a high water table will
have a short lifespan, resulting in frequent backups.
Septic pumping maintenance and inspections

3. Apart from the general lifespan of a septic tank, you can extend its longevity
for more years by following periodic inspections and proper maintenance.
Whether you are buying a new home or shifting to an older home, professional
maintenance and inspections give you eternal peace of mind knowing that
your septic tank is working optimally and is in good condition. Furthermore,
pumping it every two to three years will help you avoid costly repairs or
replacements.
