What is potable water in NZ?

The new water service regulator Taumata Arowai enforces the Water Services Act (2021) to ensure everyone in Aotearoa can access safe water. It defines “drinking water” and specifies “safe” and “potable” regarding drinking water.

Therefore, potable water is drinking water that is fit for human consumption. This means it is safe to drink, doesn’t contain any health-threatening substances and consequently complies with the Water Services (Drinking Water Standards for New Zealand) Regulations 2022.

Potable Water – Let’s get clear about what it is… and not is

Why is it called potable water?

What is non-potable water

It is called potable water because...

Potable water is freshwater with such a high degree of purity that – according to the defined quality requirements – it is classified as suitable for human consumption, especially for drinking and food preparation.

The term “potable” comes from the Latin – Potare: to drink.

Therefore, potable water is defined as any water used for drinking, cooking, and preparing food and beverages. Furthermore, it is used for domestic purposes, like personal hygiene, cleaning objects intended to come into contact with food (glasses, crockery, cutlery), or the human body (clothing, laundry).

However, potable water may only contain substances or organisms in specific quantities for which either no limits have been set, or the limits are not exceeded or undercut. For example, it must not contain pathogenic microorganisms.

Non-potable water is ...

Non-potable water contains unwanted impurities that make it unfit for human consumption. Surface water from rivers, lakes or reservoirs can contain minerals like nitrates, heavy metals or pesticides from farming. Drinking water sourced from rainwater harvesting often contains contaminants, bacteria like E.Coli, viruses, parasites, animal faeces, and chemicals. If the water source is a bore or spring, chemicals and heavy metals like iron or manganese are often present.

Only by professional water treatment, non-potable water receives a water quality that meets the drinking water standards of NZ. A water test will clarify which contaminants are present in the water supply and which technology is most suitable. UV filtration and ozone water treatment purify non-potable water into safe drinking water. This way, you comply with the legal obligations.

How is potable drinking water produced?

Drinking water is a natural product. In New Zealand, it is obtained from various water sources: stormwater, surface water, spring water and groundwater (underground aquifers). Potable drinking water is produced by the professional treatment and purification of the natural water source like rainwater, river water or bore water. However, drinking water must not contain any pathogenic microorganisms, bacteria or viruses, toxic chemicals or faecal matter.

Professional water treatment is essential, especially for health reasons. Non treated water can cause serious gastroinestinal problems like diarrhoea and vomiting. Safe water must be tasteless, odourless and colourless. Above all, it must be free of any pathogens. Therefore, strict and conscientious controls are necessary to guarantee safe and healthy drinking water.

Potable Water & Drinking Water Standards NZ

NZ Drinking Water Standards
Safe drinking water for NZ ...

Drinking water standards in New Zealand are guidelines established by Taumata Arowai to ensure that the water supplied is safe for human consumption. These standards set out the maximum levels of contaminants allowed and, therefore, determine whether or not water is potable.

If the contaminants in a water source are below the maximum levels established by the drinking water standards, and the water has been properly treated to remove any harmful substances, then it is considered potable and safe for human consumption.
