How Many Types Of Septic Tanks Based On Materials

Septic Tanks are classified into ( Four Main Types ) based on the materials used in their construction. They are,

1. RCC Septic Tanks.

2. Plastic Septic Tanks.

3. Steel Septic Tanks.

4. Fiber-Reinforced Septic Tanks.

1. RCC Septic Tank :

These are the widely used type of septic tanks due to their added advantages. The heavier structure and tension-taking properties of the RCC septic tank make them fit for all types of weather and soil conditions.

They are good at resisting buoyant force acting over them from all sides.


2. Plastic Septic Tank :

Usually, polyethylene plastics are used in manufacturing these types of tanks. The plastic septic tanks are lighter in weight when compared to RCC & steel tanks. These tanks are easier to transport & install as they are nearly 3 times lighter than RCC septic tanks.
Plastic septic tanks are rustproof and have good chemical resistance properties. They cost less when compared to all other types of septic tanks.

The main limitations of these types of tanks are, they cannot bear the high external pressure exerted over them. You have to avoid using them in collapsible type soft soils, especially in the heavy rainfall areas, where there is a continuous flow of water.

3. Steel Septic Tank :

Nowadays, steel septic tanks are rarely used due to their high cost & lower life span. They get rusted and fail by creating punctures at the corroded areas.  Due to their drawbacks, steel septic tanks are getting replaced by the other three types.


4. Fiber-Reinforced Septic Tank :

Fiber-reinforced septic tank

Due to the reinforcement of fiberglass, they are tougher and stronger in withstanding the external pressures when compared to plastic septic tanks. Similar to the plastic tanks, they are rustproof, waterproof, and lighter in their weight.
Fiber-reinforced septic tanks are easier to handle and install. Comparatively, they cost slightly more than plastic tanks.
