What it means if your drinking water supplier is exempt from some of the requirements in the Water Services Act 2021.

Drinking water suppliers are able to apply for exemptions from some requirements of the Water Services Act 2021 (the Act).

Types of exemptions

The types of exemptions drinking water suppliers can apply for are:

  • General exemptions

Allow drinking water suppliers to be exempt from complying with a range of legislative requirements. In some situations, it may be unreasonable or impractical to comply with legislative requirements. An exemption can only be granted if it is consistent with the main purpose of the Water Services Act 2021, which is to ensure that drinking water suppliers provide safe drinking water to consumers.

  • Residual disinfection exemptions

Allow drinking water suppliers with piped supply networks to supply drinking water without using residual disinfectants like chlorine. Chlorine is the most common form of residual disinfection for drinking water. An exemption may apply to all or a part of a supply. An exemption can only be granted if it is consistent with the main purpose of the Water Services Act 2021 and if all other legislative requirements will be complied with, including the duty to provide safe drinking water.

  • Class exemptions

General or residual disinfection exemptions that apply to a class of drinking water supplier, rather than a specific drinking water supplier.  Any supplier who comes within the description of the class can choose to rely on the published exemption, without having to make a fresh exemption application.

Exemptions can be issued for a maximum of five years and may have conditions that suppliers must comply with.

Before a class exemption is granted, we must consult with the public. Information about consultation will be provided on our website.

Exemption applications are subject to fees and charges set through regulations.

Current exemptions

If your drinking water supplier has been granted an exemption this will be recorded on the public register of drinking water supplies.
