Reducing water consumption in the home is a simple and easy way to decrease water and energy bills and reduce your household's impact on the environment.
Scarce water resources are conserved reducing the need to dam rivers, less waste water is produced and treated at sewage plants and greenhouse gas emissions are reduced.
Low cost water reduction can take place in every household, often with costs recouped through water and energy savings within one year.
- Reduce indoor water use by choosing water efficient showers, toilets, taps and appliances.
- Minimize outdoor water use through reducing grassy areas
and planting native species. Minimize paving of outdoor areas as this
increases heat radiation and water runoff from the site.
[See: Outdoor Water Use] - Wash cars and bikes on the lawn so that the grass is watered at the same time.
- Sweep your paths and drives instead of hosing them down.
- Reuse water where possible.
The shower is one of the easiest and most
cost effective places to decrease your water use.
An inefficient showerhead can use more than 20 litres of water every minute while an efficient AAA rated one will provide a high quality shower using a maximum of 9 litres every minute. Depending on the model you choose it is possible to get additional features such as massage, self-cleaning, and flow cut-off control.
AAA-rated showerheads cost about the same as conventional ones but can save around $100 annually on household energy and water bills. This is because they use less water and less hot water, meaning less energy is used for water heating. Prices for efficient showers range from $17 to $200. The average price is around $45.
Fitting an AAA rated showerhead takes about 10 minutes for a plumber or experienced handy person. Don’t forget to use plumber’s thread tape.
The environmental benefits are:
- Lower water use.
- Decreased wastewater volume.
- Reduced CO2 emissions from reduced hot water
use.
There are many ways to reduce the amount of water used by your toilet:
- Use the half-flush button when appropriate.
- Insert a water displacement device into your tank if you have a single flush toilet. You can purchase these or place a plastic bottle filled with water in the cistern. Make sure it doesn't’t obstruct the mechanism. Don’t use bricks as they can crumble and stop the system working properly.
- Have your plumber adjust the flush volume of your cistern.

Fix leaking toilets immediately. A slow, barely visible leak can waste more than 4,000 litres per year. Visible, constant leaks can waste NEARLY 100,000 litres.
-
Check for leaks by placing a couple of drops of food colouring or dye into the cistern. If colour appears in the bowl within 15 minutes without flushing, then a leak exists. Repair the leak.
-
Replace the toilet with a 6 litre/3 litre dual flush toilet. Dual flush toilets are required in many places in Australia and soon Europe no doubt and most cisterns available in stores are 6 litre/ 3 litre dual flush...whether required or not they still save money....
-
Replace the cistern on an old toilet with a 9 litre/4.5 litre cistern if replacing the entire unit is not an option.

The most water efficient environmentally friendly toilet is a waterless toilet, of which there are a range of models and types available. They work with no odour and little maintenance while providing excellent compost. For more information on waterless toilet systems [See: Waterless Toilets]
There are a number of things you can do to ensure that your taps are not using more water than necessary.
Fix leaks immediately.
A tap leaking at the rate of one drip per second will waste more than 12,000 litres of water a year.
- Don't over tighten taps. This can wear the washer and cause leaks.
- Install a flow regulator on kitchen and bathroom sink taps.
- Ensure that all new taps are water efficient. Look for the AAA rating.
- Install mixer taps in showers. They can reduce the
potential for scalding and save large quantities of water wasted through
running the shower while trying to get a comfortable water temperature.
- Install separate hot and cold taps or mixer taps that
provide cold water only in the middle position over basins and sinks. Mixer
type taps are usually left in the middle position. This means that each time
the tap is run for a glass of water or to rinse a toothbrush, hot water is
drawn off just to cool in the pipe without ever being used.
The laundry is a great place to reduce your water consumption and is a potential source of water for your garden. There are a number of ways to improve the efficiency of your water use in the laundry.
Adjust the water level on the machine so it is appropriate for the size of the load. Try to wash only full loads of laundry and use the 'economy' cycle if you have one.
Use the 'suds saver' function if your machine has one.
Divert the wash water from your laundry to other uses, such
as flushing your toilet or watering your garden. You will need to check with
your council to make sure this is allowed and installed to comply with
regulations.

Purchase a water efficient washer. Most front loaders are efficient, and there are now some efficient top loaders on the market. They will save 50 litres or more per load. Water efficient washers also use less detergent (the big money saver).
A couple of simple ways to use your water more efficiently when washing dishes are:
Avoid rinsing prior to washing. Scrape food remains off dishes and dispose of them in the compost or garbage bin rather than rinsing them away.
Always use a plug in the sink rather than letting the tap run continuously.
Use a sink strainer to remove food scraps from the waste water.
Some newer model dishwashers are very water efficient and can use less water than if you wash dishes by hand (depending on your water use habits). The water use of dishwashers can range from 1.6 litres to 4.8 litres per place setting, with efficient machines using 18 litres of water or less per cycle.
Always try to fully load the dishwasher before using it and use the 'economy' cycle if you have one.
In-sink waste disposal units use water when operating and also mix waste water with food scraps. Rather than using in-sink disposal units, dispose of organic waste material in a compost heap or worm farm.
Storage water heaters release water through a release valve when they are heating water. Have a professional check the release valves on your water heater. The amount of water used may be minimised by setting the release rate to the minimum recommended by the manufacturer. Turn your heater off when going on holidays so that water is not being heated and wasted while you are away.
Evaporative air conditioners have a bleed valve that releases water while the air conditioner is in use. Ensure that the bleed valve is set to the minimum required for the air conditioner to work with your water supply. Make sure the air conditioner is turned off when you go on holidays.
