Water is essential for all life and is the most abundant substance on Earth, yet water scarcity is one of the biggest issues facing us today. Australia is the world’s driest inhabited continent and 2019 was the hottest and driest year on record.
There are many ways to be waterwise.
In the home
- Take shorter showers.
- Use the half flush button on your toilet instead of the full flush button.
- Turn taps off when brushing teeth
- Check for dripping taps
- Only run the dishwasher or washing machine went it is full
- Don’t put rubbish or chemicals down the drain.
- Don’t turn the tap on too hard while washing your hands and turn off it properly.
- Use a broom instead of a hose to clean paths and driveways.
In the garden
- Water the garden early in the morning or in the evening because less water evaporates when it is cooler.
- Plant Australian plants that are native to your area and mulch your garden.
- Find alternatives to fertilisers and pesticides that may contain harmful chemicals.
- Wash the car on the lawn.
- Reuse your bath water for plants
- Check for dripping taps
- Collect rain water to use in the garden
