EVERYTHING YOU NEED TO KNOW ABOUT SEPTIC TANKS IN AUSTRALIA
WHAT IS A SEPTIC TANK? A septic tank is an underground chamber, typically made of concrete, fiberglass, or plastic. It collects household wastewater, including blackwater and greywater, for basic biological treatment. Solids settle to form sludge, fats rise to create scum, and the clarified effluent is sent to a soak-away or drain field for natural soil-based treatment.
TYPES OF SEPTIC SYSTEMS USED IN AUSTRALIA Conventional Septic Tank System Relies on anaerobic bacteria in a sealed tank to break down waste. It is suitable for properties with good soil absorption and is usually the most affordable option. Effluent flows to absorption trenches in the drain field. Aerated Wastewater Treatment Systems (AWTS) Incorporate an aeration chamber to use oxygen-loving bacteria for better treatment. These systems create effluent that is clean enough for reuse in garden irrigation. They are perfect for environmentally sensitive areas or locations with limited space. Sand Filter and Constructed Wetland Systems Use extra filtration through a sand bed or planted reed beds to improve effluent quality. These systems are often used when soil conditions are poor or for better environmental performance.
KEY ADVANTAGES: Lightweight and durable, these tanks are easy to install with manual or light machinery. They resist cracking from soil movement. Certified performance meets Australian standards, which ensures structural integrity and protects against seepage. Cost-effective, these tanks are cheaper to make, ship, and install than concrete options. No leaks and no corrosion: Unlike concrete, poly tanks are not porous and will not degrade over time. A medium-sized household, with 4 to 5 people, typically uses the 3,000 L model, which weighs around 200 kg. For larger needs, the 5,000 L version, weighing about 300 kg, is also available.
FINAL THOUGHTS Poly septic tanks, like those from The Tank Factory, offer strength, flexibility, and cost efficiency. This makes them a popular option for many Australian homes that are not connected to the main sewer. They meet AS/NZS standards and are easy to install and maintain, especially for standard homes. However, choosing the right system should consider soil type, household size, council rules, and the desired quality of effluent. Whether you choose a regular poly septic system or a more advanced AWTS or sand filter solution, proper installation, regular servicing, and responsible use are essential for long-lasting performance and environmental safety.
