Different Types Of Septic Tanks In Alabama

The 4 Types of Septic Tanks – Advantages & Disadvantages

Over 21 million American homes use a septic tank, a solution that is becoming a valid alternative to public sewer lines thanks to its affordability, accessibility, and sustainability. Switching to a septic system can be a great option for those homeowners who wish to live off-grid and increase their property’s efficiency. 

Nonetheless, not all septic tanks are created in the same way. And, when looking at the different septic systems you can install in your home, you will realize that you can choose from a wide range of alternatives. 

In fact, septic tanks come in a variety of forms, sizes, and materials. An expert Economy Septic Tank Service installer will help you make the best choice for your home. In the meanwhile, here is an overview of the different types of septic tank systems, their uses, and benefits to help you get started. 

Concrete Septic Tanks

The material used in the construction of your septic system can define its design and functionalities. 

That is why many homeowners opt for concrete septic tanks. These tanks are much bigger than their plastic or steel counterparts and are made to last for longer. Concrete septic tanks can be all-in-one systems or single-structure tanks. 

In any case, they are usually pre-casted for installation and boast a specific gravity of 2.40, which makes them far more efficient than other septic tank systems. 


  • Immune to floating thanks to their weight
  • Much longer-lasting than other types of septic tanks
  • They withstand heavy weights
  • Can withstand most weather conditions
  • They can be installed legally in all US states


  • Costlier
  • Heavier to transport
  • More difficult to repair
  • They can be susceptible to corrosion

Steel Septic Tanks

Steel is extremely lightweight – a property that makes it an appealing choice for septic tank construction. However, the high cost and reduced durability of steel septic tanks have made them a choice for few homeowners. One of the main downsides of steel septic tanks is that they don’t withstand corrosion too well and require constant maintenance. 



  • Steel is prone to corrosion
  • Steel septic tanks aren’t durable and don’t benefit from a long lifespan.
  • Costly
  • Hard to remove from the grounds

Fiberglass Septic Tanks

Fiberglass is one of the best materials for a long-lasting, efficient tank system. Fiberglass tanks, which are made of fiber-reinforced plastics (FRP), boast a high chemical resistance and great thermal properties. While stronger than plastic tank systems, fiberglass septic tanks are lighter in weight, more durable, and easier to install and handle. 


  • Highly durable
  • Withstand rust, water infiltration, and chemicals
  • Stronger than plastic tanks
  • Easier to handle


  • They are prone to float

Plastic Septic Tanks

Plastic septic tanks are the most popular models in use in homes around the US. Plastic tanks are often made of polyethylene plastic. This characteristic makes them highly durable, resistant to corrosion, and extremely light in weight. Due to their lightweight and specific gravity of 0.97, they are prone to float. That is why their installation involves installing anchoring systems to prevent the tank from moving or shifting.


  • Very economical
  • Long-lasting, durable, and resistant to corrosion
  • Lightweight and easy to handle
  • Rustproof and resistant to chemicals
  • Hard to crack


  • It may float
  • Heavy weight can damage the tank’s structure
  • Installation may require the installation of an anchoring system
