Australian Standards for Poly Water Tanks

What are Australian Standards?

Australian Standards are carefully developed guidelines that set out specifications, procedures, and best practices to ensure products, services, and systems are safe, consistent, and reliable. They are created and maintained by Standards Australia, with input from industry experts, regulators, and consumer groups.

Standards apply across many areas, including:

  • Consumer products and services

  • Environmental management

  • Construction and building

  • Energy and water utilities

  • Health and safety

Because technology and materials evolve, Standards are regularly reviewed and updated to ensure they reflect current best practice.

For customers, buying a product that complies with Australian Standards provides confidence that it has been independently tested, verified, and proven to meet strict safety and performance requirements.


AS/NZS 4766 – Polyethylene Storage Tanks for Water and Chemicals

When it comes to water tanks, the key benchmark is:

AS/NZS 4766:2006 – Polyethylene Storage Tanks for Water & Chemicals

This Standard sets out the design and manufacturing requirements for polyethylene tanks used to store water and certain chemical solutions under normal atmospheric conditions.

The Standard covers:

  • Material quality – ensuring the polyethylene is suitable, UV-stabilised, and safe for use in Australia’s tough climate.

  • Wall thickness & strength – tanks must be manufactured with the correct thickness to withstand long-term water storage pressures.

  • Structural integrity – tanks must perform without deformation, cracking, or failure when installed correctly.

  • Manufacturing consistency – strict guidelines for moulding processes, testing, and quality control.

  • Longevity – tanks are designed and tested to last for many years in harsh outdoor environments.

In simple terms: tanks that meet AS/NZS 4766 are built to perform safely, reliably, and consistently.


Why Australian Standard Certification Matters

Not all water tanks on the market are created equal. Some may claim to be "made to standard" without being independently tested or certified.

Choosing a tank that is independently certified gives you peace of mind:

  • Proven compliance – the tank has passed rigorous third-party testing.

  • Trusted quality – materials, design, and manufacturing are regularly audited.

  • Safe for drinking water – tanks must use virgin food-grade polyethylene (not recycled plastic).

  • Built to last – designed for Australian conditions, including UV exposure.

This means your investment is protected and your water supply remains safe.

Tankworld Tasmania – Certified Quality You Can Trust

At Tankworld Tasmania, every poly water tank we manufacture is independently certified by BSI (British Standards Institution) to meet:

AS/NZS 4766:2006 Polyethylene Storage Tanks for Water & Chemicals

  • Certification Licence: BSI BMP 713704

This certification proves that our tanks are not just “designed to standard” but are audited, tested, and guaranteed to meet the Australian Standard every time.

When you choose a Tankworld Tasmania water tank, you’re choosing:

  • A locally made product, purpose-built for Tasmanian conditions.

  • A tank backed by independent third-party certification.

  • The confidence that comes from over 30 years of local manufacturing experience.

In summary: Not all tanks are certified. Tankworld Tasmania tanks are. That’s why Tasmanians trust us to protect their most precious resource – water.
