National Water Labelling System
The Water Conservation and Labelling Scheme was launched nationally in October of 1994 and it provides consumers with a simple way of choosing the most water efficient appliances and fittings.
The rating scheme indicates the water efficiency of various products using a three level ratings system:
A- An acceptable level of water efficiency
AA - A high rating
AAA - An excellent rating
Product manufacturers and distributors have their appliances tested for water efficiency by an independent approved laboratory in accordance with the requirements of the related Australian Standard.
For example, a shower rose that uses a maximum of 15 litres per minute will be issued an A label, for 12 litres of water per minute an AA label and for 7 litres per minute an AAA label.
Initially, the scheme covers shower roses, dishwashers, toilet suites, urinals, taps and washing machines. Other water using appliances will progressively be covered by the scheme.
Shower Heads
Low flow shower heads use much less than a standard shower. Although some low flow shower heads once had a reputation for not providing a very good shower, times have changed and most people are extremely happy with the models now available.
It is worth noting however, that some low flow types are not well suited to low pressure hot water systems, so you should ask a reputable supplier about them and read the available product information before you purchase one. Some low flow showerheads use less water than others, so you should also check the product information and choose one of the more efficient models that suits your situation.
An alternative to low flow showerheads is a shower flow control device. These restrict the flow of water to the shower. They are not suitable for every situation, for example if your shower water is delivered at low pressure, so if you are considering this option you should check the product information and supplier to ensure it is appropriate for your home.
Shower flow control devices can be a handy alternative to low flow showerheads if your preference is to purchase a water inefficient showerhead, for example, because you prefer a particular model’s appearance over the available water efficient models. Flow restrictors are also available for household taps.
Dual Flush Toilet
All new homes must now be fitted with a dual flush toilet. A dual flush system gives you the option to flush either half or all of the cistern water. Hence, installing a dual flush toilet can save between 22,000 and 35,000 litres of water per year.
Washing Machine
A number of washing machines models have been rated under the National Water Conservation Labelling Scheme as AAA (a high rating), or better. In general, front loading washing machines are much more water efficient than top-loading machines, however there are a few models of top-loading machines that are rated AAA.
If you use hot water when washing clothes, then a water efficient machine, will also save energy by using less hot water. However, if you normally use only cold water for clothes washing, you should be aware that front loaders, although water efficient, usually come with a built-in water heating unit - so it might be less energy efficient for you than an efficient top-loading machine.
Although water efficient washing machines may cost more than less efficient machines, if they are regularly used, they can pay for their additional cost in just a few years by reduced water and energy bills.
TAP Aerators
Install aerators on taps. Flow controlled aerator adaptors are easy to install and can reduce the water flow from between 15 litres per minute to either 6, 9 or 12 litres per minute.Hot Water Systems
Insulate hot water pipes. This avoids wasting water and power while waiting for hot water to flow through. Make sure your hot water thermostat is not set too high, adding cold water to cool the temperature of water is wasteful.
