Water saving tips

We’ve got some of the best water in the world, so let’s use it wisely. When it's hot, demand rises and we may use water faster than we can fill reservoirs or get it to you. We need your help to prevent this, so we’ve compiled some water-saving tips.


Get the family together!

Talk with your family about ways to save water or challenge each other around what they did today to reduce their waste.

Check for leaky taps.

Check all taps on your property for leaks. Even one drip a second can waste over 5,000 litres per year.

Ensure your garden retains the water it needs.

Water before 6am or after 9pm, and only when it's not windy, otherwise water can evaporate before being used by plants.

Target water to plants that really need it.

Use a trigger gun nozzle on a hand-held hose or watering can.

A rainwater tank is a great investment.

A tank ensures you have fresh water available, and can be a key water source for your family in a natural disaster.

Gardens don't need water every day.

Try watering on alternate days: even street numbers on even days, odd street numbers on odd days. A deep soak is better than frequent light watering.

Keep your shower under 5 minutes.

Install a shower timer (or water-efficient shower head) and save up to 3700 litres of water per month!

Make water conservation a fun game for your family.

Set a challenge for everyone to turn off the tap while brushing their teeth.

Use your dishwasher wisely.

Ensure that your dishwasher is full before running a load.

There are alternatives to using running tap water.

Wash fruit and vegetables in a bowl of water, then pour the water onto pot plants.

Washing machines account for up to 20% of water used in most homes.

Use a more water-efficient front loader and ensure you always have a full load.

Every action to conserve water helps.

Reducing laundry by one load can save up to 50 litres of water per week!

Why saving water is important

Keeping consumption down protects our supply for future generations, reduces infrastructure costs as well as the likelihood of supply issues at peak times.   

When water use is very high, such as on hot summer days, you may be using water faster than we can pump it and fill the reservoirs. This can lead to supply issues in extreme cases and reduced pressure in parts of the city. Maintaining pressure is especially important for fighting fires.

We're also mindful that in the longer term, as the city grows and demand for water increases, we may reach a point where we will be using water at a rate greater than the aquifers recharge. 

A key way you can conserve water is to check all taps on your property for leaks. Even one drip a second can waste over 5,000 litres per year.

  • Water your garden at cooler, less windy times of the day, to ensure your plants retain the water they need.
  • You don’t need to water your plants every day. Watering your garden once every few days is fine, especially if you have chosen drought-tolerant plants. 
  • Instead of sprinklers or irrigation systems, use a trigger gun nozzle on a hand-held hose instead to target water to the plants that really need it.
  • Use mulch to keep your garden cool and moist.
  • Set your lawn mower to leave grass slightly longer. Short grass dries out sooner.
  • On hillside gardens don't apply water faster than it can get into the soil.  


  • Turn off the tap when cleaning your teeth or shaving – you could save 10 litres of water a minute.
  • Reduce your shower time to three minutes or less.
  • Install water-saving shower heads or flow restrictors.
  • Keep baths to a minimum.
  • Check your toilet for leaks. Put a few drops of food colouring in your toilet tank. If it appears in the bowl without flushing, you have a leak that needs repairing.


  • Rinse or peel vegetables in a bowl or sink filled with water instead of running the tap – you could save up to 10 litres for every minute the tap is turned off.
  • Wait until you have a full load before starting your dishwasher. When possible, use the eco-setting.
  • Rinse dishes in a sink filled with water, rather than under a running tap.
  • Keep a jug of drinking water in the refrigerator instead of running the tap water until cold.


  • Wait until you have a full load before starting your washing machine, or use the partial load settings.
  • Turn off all taps when not in use.


  • Use a broom to sweep your driveway rather than hosing it clean.
  • Wash your car with a bucket of water on the lawn and you'll water your lawn at the same time.
  • Report broken pipes, open hydrants and errant sprinklers to the property owner or the Council.
