Types And Sizes Of Septic Tank

Modern plumbing contributes significantly to the improvement of our quality of life and the prevention of the spread of disease. Systemic delivery of safe drinking water, as well as the removal of sewage and wastewater, are provided by plumbing. 

When it comes to draining wastewater from residential and commercial buildings, there are two options. Structures will be connected to municipal sewer lines or will be equipped with a septic system. The most significant distinction between the two is that a septic system serves a single property, whereas sewer lines connect numerous properties together into a network of pipes that transport waste to a municipal wastewater treatment plant for treatment. Compared to rural homes, sewer lines are more widespread in urban areas, and septic tanks are more common outside of city borders on rural properties.

Septic tanks constructed from a variety of materials have different degrees of strength and longevity. Here is a breakdown of the advantages and disadvantages of the most prevalent types of septic tanks.

These long-lasting tanks are capable of lasting for several decades. If the concrete breaks, however, this type of tank may allow waste to leak out while also allowing groundwater to seep into the tank itself. The blockage that can form in a concrete septic tank when a backup occurs can have an impact on the outflow of water.


Despite the fact that steel is a naturally durable material, septic tanks made of steel typically only last 25 years before they begin to corrode and leak. In order to mitigate this risk, steel septic tanks are less commonly used in residential settings. When corrosion begins to form on the roof of a steel tank, the tank’s structural integrity may be compromised, making it incapable of supporting the weight of the earth above it. It is possible that an animal or a person will fall into the tank if this occurs. If the rest of the tank is physically sound, it may be possible to change the cover of a steel tank in order to save money. Property owners should keep an eye out for rust formation on the baffles at the entrance and exit points.


Fiberglass septic tanks will not crack or rust like concrete or steel septic tanks, for example. They are also substantially lighter than tanks made of other materials, making them quicker to install but also making them more susceptible to shifting as the surrounding soil becomes saturated.


Plastic tanks are long-lasting, lightweight, and economical compared to other materials. When opposed to concrete septic tanks, plastic septic tanks will not rust and will be less prone to cracking. These tanks are extremely lightweight, which makes them simple to set up. However, because they are so light, they are susceptible to damage during the installation process. Furthermore, if plastic tanks are not fitted correctly, they may float to the surface of the water.

Septic tanks are aerobic in nature. These tanks are powered by electricity and are frequently used in situations where other tanks on a property have failed to function properly. Compared to other types of septic tanks, aerobic tanks are up to three times more expensive; however, they are more effective and require smaller drain fields, which can be a significant benefit for smaller properties. Maintenance on these tanks must be performed on a more frequent basis, although they can last for many years.
