Water conservation

One of the purposes of the Building Act 2004 is to promote sustainable development. This includes the efficient use of water in buildings. The Building Code already allows for the use of non-potable water in certain circumstances.

Non-potable water, including collected rainwater, may be used for laundry, bathing and toilet flushing. Potable water, usually sourced from the reticulated supply, must be used for drinking, teeth cleaning, cooking and utensil washing, and must be supplied to the kitchen sink and the bathroom vanity. Pipes and outlets supplying non-potable water, such as bath, shower, toilet or laundry tub, must be clearly identified.

Rainwater may be made potable by treatment. This could include filters and/or sterilisers (for example, UV or ozone). Only potable water should be consumed because of the dangers of biological or chemical contamination.

Other ways to save water in the home include reduced-flush toilets, water-efficient showerheads and aerator taps for kitchen and bathroom sinks.
