Good waste management is vitally important in every home, as well as at commercial sites. Part of this is making sure that wastewater is collected and drained effectively, and having the right septic tank installed is essential for this. Without the right septic tank in place, things can quickly become very unhygienic. You might be uncertain of the right size of septic tank for your property, so in this blog post, we look at what size septic tank you need for homes in Australia.
A septic tank is a watertight container that’s buried underground and is used for collecting and storing wastewater from your home or business. It holds water for long enough to allow solids to separate from the water and then allows the water to drain out into a drain field.
Septic tanks can be constructed from fibreglass, plastic, or concrete. At Graham’s Precast Concrete Products, we specialise in high quality concrete septic tanks that are both safe and durable.
Septic tanks allow waste to separate into three layers: sludge, wastewater and scum as it is shown in this below diagram. The solids settle to the bottom, where microorganisms decompose them. The middle layer travels through the septic pipes and eventually leave the septic system and empty into the drainage field.
The bigger or busier your property is, the larger the septic tank you’ll need.
The answer will vary from person to person – every property is different and has different waste management demands. However, Standards Australia has issued guidelines on septic tank sizes. In line with this guidance, a house with between four and six bedrooms must have a tank that is at least 4,500L in capacity. This applies if you are producing “regular” quantities of wastewater. If your property produces more for any reason it’s possible that you’ll need a larger septic tank.
There isn’t a one size fits all approach when it comes to septic tanks, and problems are likely to arise if you get things wrong. To make sure you get the right sized tank to meet your needs and keep waste management running smoothly, it’s advisable to speak to professionals to work out what the right choice is for you.
