When it comes to choosing the best septic tank for a septic system, there are a few factors to consider, such as the size of the tank, the material it’s made from, and the overall cost.

Firstly, the size of the septic tank should be determined by the number of people in the household and their water usage. A general rule of thumb is that a family of four will require a septic tank with a capacity of at least 1,000 gallons or roughly 3,785 litres. However, if there are more people in the household, or if there is heavy water usage due to things like frequent laundry or long showers, a larger tank may be necessary.

Secondly, the material of the septic tank is also important to consider. The two most common materials used for septic tanks are concrete and plastic. Concrete tanks are durable and long-lasting, but they can be more expensive to install and are prone to cracking over time. Plastic tanks, on the other hand, are lightweight and easy to install, but they may not be as durable as concrete tanks.

Thirdly, the cost of the septic tank should also be taken into account. While plastic tanks may be less expensive upfront, they may require more frequent maintenance and replacement than concrete tanks, which could end up costing more in the long run.

In general, a high-quality concrete septic tank that is properly installed and maintained can last for several decades and provide reliable and efficient wastewater treatment. However, it’s always a good idea to consult with a professional septic system installer or contractor to determine the best septic tank for your specific needs and budget.

At Septic System NSW we recommend and offer our clients concrete tanks as the long-term cost and durability of the tank outweighs that of plastic tanks. The cost may be less upfront with plastic tanks however, the long-term costs can exceed that of concrete septic tanks by so much more.
