Septic Tanks buried under groundWith the growth in world population, there is a significant increase in wastewater. The number one choice for communities worldwide for wastewater treatment is natural treatment. The key features of this system are simplicity, cost-efficiency and reliability.

The primary natural wastewater systems include lagoons, phytodepuration and storage in septic tanks. Though the containers are durable, you will need to check if there is any need for septic vessel replacement. Here are the options available:


Concrete septic tanks are durable for several decades. However, they are prone to separation and cracking, leading to pollution of groundwater. This is dangerous and is only discovered through a dye test on your groundwater. Periodic inspection of concrete septic tanks is vital to detect any issue early.


This material is not a popular option since it is not very durable. Steel is highly susceptible to rust, and the cover of the tank can give way when stepped on by unsuspecting individuals. If your property has a steel septic tank, pay attention to the exit and entry points of wastewater because these tend to rust first.


Plastic septic tanks are impervious to rusting and cracking like steel and concrete tanks. Though durable, the containers are prone to blockages that slow down the flow of liquids from the reservoir. Since plastic is a lightweight material, the tanks are also at risk of structural damage. Hence, careful installation is vital.

The given types of septic tanks are the ideal choice in areas that need a significant amount of water within a short period. Natural wastewater treatment using storage tanks is common in regions that practice irrigation. The output of these tanks is regulated to ensure a constant water supply.
