Extension activities

Teacher background information

Water use at home

Households use over 50% of their total water inside the home. Making simple changes to our habits can save lots of water. Around 40% of all household water is used in the garden.

Each year the average household uses more than three swimming pools worth of water in the laundry, kitchen and bathroom:

  • 1 swimming pool is used for the toilet
  • 1 swimming pool is used in the bathroom
  • ¾ swimming pool is used in the laundry
  • ½ swimming pool is used in the kitchen.

Ways to save water at home

Why conserve water?

  • Plants, animals and humans cannot survive without it.
  • Australia is the world’s driest inhabited continent.
  • We are vulnerable to climate change.
  • Our population is increasing and so is the demand for water.
  • Our use of water sources must be sustainable.
  • If we reduce our water use, we can also reduce our energy consumption.
  • If we reduce our water use, we can delay having to build costly new water supply sources and this helps reduce the impact on the environment.
