New  Regulatory Framework for Drinking Water in WA - 

Presented by Alison Barrett-Lennard Department of Health WA 


With the introduction of the Public Health Act 2016 in WA, the Department of Health is proposing the creation of Drinking Water Regulations. 

These will replace the provisions in the Health (Miscellaneous Provisions) Act 1911 relating to the safety of drinking water.


The five (5) key features of the proposed regulations are:


1. Set out the registration and licensing framework for drinking water suppliers.

2. Clearly defined health-related standards for the quality of drinking water.

3. General risk management obligations placed on drinking water suppliers that are based on public health risk analysis, due diligence, hazard management and auditing.

4. Transparency and public disclosure of water quality information.

5. Provide flexibility to ensure that the framework is not overly onerous for smaller drinking water suppliers.
