Rural Property Sales & Rentals

Requirements for residential buildings to supply potable water.

The ongoing reform of New Zealand’s drinking water regulations is having an impact on various industries. As a property owner, property manager or landlord, you must ensure that your water is fit for human consumption and comply with the Drinking Water Standards for New Zealand 2005 (revised 2018). However, this means it is not lawful to rent, sublet or sell a house without an adequate supply of potable water. There are several things to consider when you have rural properties for sale/rent?

 

What are the main health issues?

Water can be a carrier for E. coli and giardia, amongst many other bacteria, viruses and protozoa. E.Coli can cause health issues requiring hospitalisation, especially for infants, children, and people with weak immune systems. Giardia, a notifiable disease, is increasingly being found in rainwater tanks in New Zealand. Coliforms include bacteria in water from surface water and human or animal waste. We have worked with many families who have suffered severe health problems due to e. coli in their drinking water. Aqua Works has over 20 years of experience in helping property owners comply with New Zealand Water Standards. Consequently, what are the implications if you have rural properties for sale/ rent?

Are you renting a house on tank water?

Landlords in New Zealand must legally provide safe and potable drinking water to their tenants. Potable water means it is safe to drink and complies with the Drinking Water Standards for New Zealand 2005 (revised 2018). These standards cover all water sources, including rainwater, bore water, surface water supply (e.g. creeks or springs) and mains water supply.

What do you need to do to comply with these legal requirements?

Are you selling a house without potable water?

Are you selling a house and have a rural water supply? Is your property for sale and connected to a rainwater harvesting tank? Did you know that it is illegal in New Zealand to sell a house without a potable water supply?

Basically, if your property does not have a UV filtration system or better, you cannot guarantee that it will have safe and potable water. What do you need to know to meet the legal requirements?

Legal basis for providing potable water

Currently, most rentals do not comply with the Drinking Water Standards for New Zealand 2005 (revised 2018), which is why tenancy tribunals are now forcing landlords to ensure they do. Also, buildings for sale do not comply with the legal requirements in many cases. What are the legal requirements for potable water when renting, subletting or selling a house?

Legal basis for potable water

If you have rural properties for sale/rent, you need to comply with the following legal requirements.

Health Act 1956

The legal basis for this particular requirement to have potable water when renting, subletting or selling a house in New Zealand is enshrined in the Health Act 1956 No 65 (as of 09 April 2021). It states in section 39:

(1) It shall not be lawful for any person to erect or rebuild any building intended for use as a dwelling house, or for any person to sell, or let, or sublet, or permit to be occupied as a dwelling house, any building or part of a building, unless in every such case sufficient provision is made in accordance with the building code and the Building Act 2004 for the following matters, that is to say:

(a) an adequate and convenient supply of water that is potable (as defined in section 69G), available for the inmates of the dwelling:

Building Regulations 1992

The Building Code, Section G12.3.1 following states:

G12.3.1 Water intended for human consumption, food preparation, utensil washing, or oral hygiene must be potable.

G12.3.2  A potable water supply system must be—

(a) protected from contamination; and

(b) installed in a manner that avoids the likelihood of contamination within the system and the water main; and

(c) installed using components that will not contaminate the water.

G12.3.3 A non-potable water supply system used for personal hygiene must be installed in a manner that avoids the likelihood of illness or injury being caused by the system.

G12.3.4 Water pipes and outlets provided with non-potable water must be clearly identified.

 

Taumata Arowai and the Water Services Bill (2020)

Taumata Arowai is the new water service regulator of New Zealand. As part of the review of New Zealand’s drinking water regulations, the new Water Service Bill 2020 is before Parliament. This bill will clarify the definitions of ‘safe’ and ‘potable’ water:

drinking water standards means the standards issued or adopted under section 46 of the Water Services Act 2020 potable water means water that—

(a) is safe to drink; and

(b) complies with the drinking water standards

Renting a house on tank water

What are a landlord’s responsibilities?

Under New Zealand law, landlords are obliged to provide potable water free from contaminants such as E. coli, Giardia or campylobacter bacteria. These bacteria, germs and viruses pose a serious health risk, especially to people with weak immune systems, young children, pregnant women and the elderly. This means your tank/rainwater must meet NZ Drinking Water Standards on an ongoing basis.

At the same time, drinking-water suppliers are obliged to monitor total coliforms. This is the primary indicator that the drinking-water supply may be contaminated with pathogens. Currently, most rentals do not comply with NZ Drinking Water Standards, which is why tenancy tribunals are now forcing landlords to ensure they do.

Non-compliance costs

In the case where water supplied is not deemed potable due to having failed an E. coli test, the tenancy tribunal had ruled that tenants’ rent maybe be backdated to when they moved in. For many New Zealand rural homes, a rain harvesting system is their primary water source. For years, the Kiwi attitude was that rainwater was safe, blaming any illness on food. However, our water tests show that an alarming number of rainwater tanks do not comply with the Drinking Water Standards for New Zealand 2005 (revised 2018).

Landlords need to know and understand their obligations, while tenants need to be clear on their rights relating to their water supply.

Aqua Works offers permanent solutions for the supply of potable water

Implications for Landlords

Landlords have to provide a permanent solution to ensure drinking water is potable. As defined in the Water Services Bill, 2020, drinking water is used for “oral hygiene or preparing food and drink, washing utensils that are used for eating and drinking, or for preparing, serving, or storing food or drink for human consumption.” Thus, landlords need to install a treatment method on the water supply line to eliminate the risks of E. coli and Giardia, amongst other bacteria, viruses and protozoa. Aqua Works offers various water treatment applications to ensure potable water permanently.

 

Aqua Works – your expert for professional water treatment

Several technologies guarantee safe potable water:

The most cost-effective guarantee of safe potable water is an ultraviolet system that includes sediment filters. A UV water filter kills 99.99% of all microorganisms, such as algae, protozoa, bacteria and viruses. As we only install quality UV systems, we source our filtration systems from Canada and Italy. All come with a 3-year warranty, the highest in New Zealand.

We will visit your property, determine what is required for compliance of potable water delivery and recommend a system that guarantees safe water, all year round.

Minimum solution for potable water delivery

Technically, this can be met by only sterilising the main kitchen tap. At Aqua Works, we custom design and install under-bench UV systems for the treatment of cold water. If this is the solution you choose, you must, by law, label all other taps in the house as being non-potable.

The most effective solution for potable water

The best solution for both landlords and tenants is to ensure all water, hot and cold, is safe to drink by installing a UV filter for the entire house: the safest, most comprehensive answer.
