Assessing drinking water systems for certification and compliance

Drinking water is an essential component to human health so it is important to ensure the safety and reliability of systems used to deliver water for human consumption.

Choosing the right drinking water system is not always easy in today’s complex regulatory landscape.

A “Good. Better. Best.” approach will help you separate products that meet the minimum regulatory requirements from those that deliver industry-leading performance and sustainability.


What is the “Good. Better. Best.” approach? An easy way to evaluate drinking water systems.

  • Good – Products that meet the basic standards for drinking water systems in Australia.
  • Better – Products that exceed the basic standards and meet established non-mandatory requirements in terms of functionality, performance, sustainability or accessibility.
  • Best – Products that go above and beyond to achieve higher certification under recognised sustainability or environmental certification programmes.


At a minimum, drinking water systems should adhere to the basic standards and mandatory regulatory requirements governing the product category.

  • WaterMark certification
  • WELS star rating (the more stars, the greater the water efficiency)
  • AS/NZS 4020:2018 “Testing of products for use in contact with drinking water


Manufacturers may choose to demonstrate compliance with other regulatory schemes and standards to offer even greater peace of mind.

  • Water Regulations Advisory Scheme (WRAS) approval
  • ISO 9001:2015 certification
  • HACCP (Hazard Analysis and Critical Control Points) product certification
  • Certified lead-free components
  • Accessibility and mobility features (AS 1428)


There are a range of schemes that certify products not just for performance, but also in terms of their sustainability, contribution to health and wellness, and environmental impact. Many of these schemes are voluntary, and require an accredited third-party certification body to evaluate the product against very stringent environmental criteria.

  • Product ecolabels: e.g. Global GreenTag
  • Industry ecolabels: e.g. Green Key
  • Sustainable building certification: e.g. The WELL Building Standard
