Down the Drain
This exhibit compares the amount of water that is used in the home for different activities.
Activity.... Do – Think - Learn
Water is vital to life. Although it is a renewable resource, there are only finite supplies. We can reduce demand by using water more carefully. Here are four ways we use water at home:
- Shower or bath
- Garden hose or watering can
- Rinse with tap or rinse with cup
- Normal toilet flush or water saver flush
Your challenge is to use as little water as possible.
How much water have you used in total?
Do you think you could have used less water?
The Science Bit
The following is water usage from around the world:
- USA 650 litres per person per day
- Sub-Saharan Africa 49 litres per person per day
- Developed countries 130 litres per person per day
- Western Australia 338 litres per person per day
- Developing countries 74 litres per person per day
- UK and Wales 149 litres per person per day
- World Average 82 litres per person per day
- Southern Water region 161 litres per person per day
