Whether you’re building a new home, replacing an old septic system, or upgrading to a modern AWTS, BIOSeptic makes the entire process easy. Every property is different — soil type, land size, council requirements, and household needs all influence which system will work best. Our team guides you step-by-step to ensure you get the right solution for your site.

1. Contact Our Team

Start by calling 1300 658 111 or submitting a quote request. A friendly BIOSeptic consultant will discuss your property, project plans, and any council or builder requirements.

We’ll help you understand your wastewater options, including:

• Aerated Wastewater Treatment Systems (AWTS)

• Traditional Septic Tanks

• Collection wells and pump wells

• Commercial or multi-dwelling solutions

2. Site Assessment & Advice

Once we understand your needs, we’ll organise a site visit or request existing reports. We look at:

• soil type and absorption capabilities

• land slope and property layout

• irrigation/disposal area requirements

• council regulations for your region

Our goal is to recommend the best, most cost-effective system for your site — not the most expensive one.

3. Geotechnical Wastewater Report (If Required)

Some councils require a wastewater design or soil test.
If needed, BIOSeptic coordinates this for you with trusted, long-term partners.

We handle all communication to ensure the design is compliant and economical.

Once your wastewater report is complete, we assist with the entire council submission.
We ensure everything meets current standards, including AS/NZS 1546.3 and local regulatory requirements.
