How Long Does a Septic Tank Last?
How long does a septic tank last? That is a question that many homeowners ask themselves at some point. The answer, of course, depends on a variety of factors.
In this guide, we will discuss the different factors that can affect how long your septic tank lasts, and what you can do to prolong its life.
The Average Life Expectancy of a Septic Tank
The average septic tank has a life expectancy of 20-30 years. Of course, this number can be affected by a variety of things – some of which are within your control, and some of which are not.
For example, the material your septic tank is made out of can affect its lifespan. Septic tanks can be made out of different materials, including the concrete, plastic, steel, or fiberglass. The lifespan of each type of tank is different – plastic and fiberglass tanks usually don’t last as long as concrete septic tanks, for example.
Factors that Influence the Lifespan of a Septic Tank
There are a few different factors that can influence the lifespan of your septic tank. These include:
1. How it is installed
A poorly installed septic tank will not last as long as a well-installed tank. If you are unsure about how to install your septic tank, or if you need help with maintenance, be sure to consult a professional.
2. The type of material it is made out of
As we mentioned before, the type of material your septic tank is made out of can affect its lifespan. Concrete tanks, as stated earlier, usually last longer than plastic or fiberglass tanks. This is because concrete is a more durable material. The tradeoff is that plastic and fiberglass septic tanks are usually much easier to install.
3. How well it is maintained
A septic tank that is not properly maintained will not last long in general, let alone when compared to tanks that are regularly maintained. Be sure to have your septic tank pumped every few years, and fix any leaks or other issues as soon as possible.
4. The size of the tank
A larger septic tank will usually last longer than a smaller one. This is because a larger tank can hold more waste and will not need to be emptied as often. The size of your tank, however, will mostly depend on the size of your home and how many people live in it.
5. The surrounding environment
The type of soil and climate around your septic tank can also affect its lifespan. Soil that is wet or clay-like will not allow the waste to decompose as well, which can shorten the life of your tank.
6. The amount of use it gets
A septic tank that is used more frequently will not last as long as a septic tank that is used less frequently. This is because more waste will build up in the tank, and it will need to be emptied more often.
7. The contents of the soil it is buried in
The contents of the soil that your septic tank is buried in can also affect its lifespan. Soil that is acidic or has a lot of organic material will not be as good for your septic tank as soil that is neutral or alkaline.
8. The type of water you use
The type of water you use can also affect the lifespan of your septic tank. Hard water can damage the tank and shorten its lifespan. You can get a water softener to help with this issue.
9. The number of people in your household
The more people in your household, the more waste will be produced and the faster your septic tank will fill up. This is why it is important to have a tank that is the correct size for your home.
