New Standards, Rules, and Aesthetic Values
As the new water services regulator for Aotearoa New Zealand, we are responsible for developing regulatory instruments (such as Rules, Standards and Acceptable Solutions) that assist us to administer the Water Services Act 2021 and ensure safe drinking water.
New Drinking Water Standards
Drinking Water Standards (Standards) set the Maximum Acceptable Values (MAVs) for a range of contaminants which can affect the safety and quality of drinking water. They are based on guideline values set by the World Health Organisation (WHO).
The Standards came into effect on 14 November 2022. We intend to publish guidance on the Standards.
New Drinking Water Quality Assurance Rules
The Rules came into effect on 14 November 2022.
We intend to publish guidance on the Rules. In the meantime, we've clarified some of the Rule interpretations in these tables.
New Drinking Water Aesthetic Values
Drinking water not only needs to be safe, but it also needs to taste and smell acceptable too.
The new Aesthetic Values for drinking water came into effect on 14 November 2022.
We intend to publish guidance on the Aesthetic Values.
We have now published our Acceptable Solutions. These Solutions provide drinking water suppliers with a ready-made option to meet their compliance obligations under the Water Services Act 2021. They apply to particular supply types and situations and must be implemented in their entirety.
These have been developed in collaboration with sector reference groups from various water supply types across Aotearoa. The commencement date for Acceptable Solutions is 14 November 2022.
