New Regulatory Framework for Drinking Water in WA - 

Presented by Alison Barret-Lennard Department of Health WA 

Western Australia only 

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.

​Alison will discuss the results on the consultation for the above (which closed on 30 August 2019), the expected implementation process and provide information on how this may impact Health2ageducate members.


Alison is the drinking water and wastewater policy expert at the Department of Health. She is an environmental engineer with over 10 years’ experience in the water industry and water quality assurance.  She was the lead officer for the drinking water regulatory review project and going forward will be responsible for the implementation of the proposed regulations in line with State Government regulation review process.
