Common Problems with Concrete Septic Tanks

Common Problems with Concrete Septic Tanks
December 19th, 2018 0 Comments

Concrete septic tanks have been around for a long time. But they are slowly becoming outdated as new technology is paving the way for an influx of new septic tank materials, and new designs.

And there are ample good reasons for this transition to more modern tanks, too. Concrete septic tanks can be prone to a number of issues that may not pop up with these newer tanks made with high-density polyethylene.

Simply put, a traditional concrete septic tank can cause headaches for homeowners from the initial installation, to years down the road when the tank starts to show its age.

So before you purchase a new tank and septic system for your home or property, consider some of the common problems with the traditional concrete septic tank.


Problems That Make Concrete Septic Tanks A Thing of The Past

Expensive Installation

When it comes to concrete septic tanks versus modern poly tanks, homeowners will see an increase in costs right from the start.

Because concrete tanks are heavier than more modern ones, they may require special equipment to transport to the site, and then lower into the ground. Depending on where your concrete septic tank is coming from, these costs can add up too. This is especially true if you live in a more rural location far away from your distributor.

Also, because concrete tanks generally take extra work to construct, the installation time may be longer than a more modern tank. Therefore, this is a definite consideration for homeowners who need to install or replace a new septic system as soon as possible.


Cracking and Corrosion

Cracking and corrosion are two common issues with older concrete septic tanks, which tend to become a growing concern as the tank ages.

These cracks can eventually lead to a world of problems. They might cause noxious waste to leak out into your local environment. Or even inefficient use as your tank struggles to maintain its optimal levels of wastewater and bacteria.



Another major problem that accompanies concrete septic tanks is rust, and this is especially true for older or less expensive models.

Essentially, concrete tanks are outfitted with steel support struts. These can easily rust over time, and can cause a slew of new problems for homeowners. The septic tank could collapse or break. Or that rust could affect your local environment. Hence it’s a concern that homeowners certainly need to consider.



Because of the aforementioned rust, cracks, and corrosion, concrete septic tanks – and especially inexpensive varieties – may need repairs after a few years of use. And when it comes to cost, it can be an expensive venture.

When a concrete septic tank has an issue, it usually corresponds with an extremely foul-smelling odor. This is because the wastewater is no longer being properly stored.

In addition, when it’s time to repair the tank, special equipment might once again be required to access the depths of the tank. You might need to replace any concrete, steel, or other structural elements that have damage.

However, with modern tanks, the tank itself is much easier to access, examine, and replace as needed. Most of all, you won’t have an issue with those cracks and corrosion to begin with.



The lifespan of a concrete septic tank varies, and it varies widely. This is determined by the amount of waste that a home produces, the materials that are flushed down the drain, and the quality of the original concrete septic tank itself.

But regardless of these factors, at some point, homeowners will likely need to replace their septic tank.

And when this occurs, removing and disposing of a concrete septic tank can be a costly endeavor.

Once again, you’ll need to hire special equipment to extract the tank from the ground and remove it from the sit. Plus, the amount of earth that may need to be dug out to do so may affect your landscape, as well as your wallet.

In short, when it comes to adding or removing a concrete tank, it takes a larger effort that the modern varieties of septic tanks don’t require.


What’s A Better Septic Tank?

If you want to minimize your costs of a new septic tank installation or replacement, it’s important to do your research. While concrete tanks have been the norm for decades, technological advancements have led to new options for homeowners who want an easier installation and eventual use.

Check out lightweight tanks, like Rotoplas’ selection of tanks with three layers of high-density polyethylene. This way you’ll minimize your costs – and your potential headaches – right from the get go.
