Bushmans 4,550L septic tank is an Australian-made durable solution designed for long-term wastewater management. This poly septic tank is engineered to withstand the structural demands of underground installation, and requires minimal maintenance. For larger properties where a municipal sewer system connection is not an option or is limited, our poly septic tanks provide a cost-effective, reliable solution built to go the distance.
Household Suitability
The 4,550L poly septic tank model is specifically designed for larger households/properties between 6–10 people. Its increased volume allows it to manage higher daily waste loads efficiently, providing the necessary buffer for busy residential or rural sites. If you are looking for a smaller system for a cottage or minor dwelling, we also offer a 3,100L poly septic tank which is available for delivery across NSW & QLD.
Certification & Compliance
To ensure total peace of mind, our poly septic tanks, including the 4,550L septic tank, are manufactured to exceed strict AS/NZS 1546 standards (final certification pending). This compliance ensures that our poly septic tanks meet the rigorous health and environmental regulations required for installations throughout NSW & QLD.
