Different Types of Septic Tanks You Must Know About!

Septic Tank

Imagine life without septic tanks.

All we would have are greased containers and dirty water.

Quite unappealing, isn’t it?

Therefore, it wouldn’t be wrong to say that septic tanks are indeed a blessing.

But there is no one type of septic tank. In fact, tanks differ in their material composition, each having distinct features.

Read along as we uncover the four basic types of septic tanks.

1. Concrete Septic Tanks

Concrete tanks have been around for decades.

These are massive and heavy tanks that are pre-casted before installation. Their heavy weight makes them durable and apt for long-term usage.

In addition, their strong foundation provides a specific gravity of 2.4, preventing them from moving and resisting the strong forces underground.

However, concrete is susceptible to crack, causing underground seepage and disturbed outflow, making it difficult to repair.

2. Steel Septic Tanks

Septic tanks are also available in formidable steel structures. However, they are not a popular choice.

While they can withstand the forces underground, steel septic tanks become rusty and have a limited life, i.e., 25 years.

The corrosion can affect the top cover of the steel tanks, which is quite hazardous since it cannot support the ground above it. Hence, even people or animals walking on a specific surface can fall.

3. Plastic Septic Tanks

Plastic is yet another popular material to create septic tanks.

The features that make it an excellent option are as follows:

  • It’s lightweight
  • It will last for a long time
  • Will not rust or crack
  • Cheap

However, low specific gravity of 0.97 is one of its shortcomings, making it float underground. Hence, engineers need to inspect the surface to prevent floating.

Another viable and similar option is fiberglass tanks. The fiberglass reinforcement makes them much stronger than plastic, making them withstand any heavy weights.

But still, they have low gravity, making them float underground.

4. Aerobic Septic Tanks

These are the new, emerging tanks in the market.

Compared to their predecessors, they are much more effective and require less land for draining.

These tanks use oxygen in their processors, allowing bacteria to consume the waste. There are disinfectant processes that treat the wastewater before discharging them on loads.

However, they can be a lot more expensive and require frequent maintenance due to their electricity use.

Provided that you maintain these tanks well, they are bound to last for a long time.
