2 How much water do you use?

You have just examined the relationship between rainfall and population. Global water use has increased over the centuries not only because the world population has increased but also because water is now used in a huge range of additional ways.

In a rain-soaked country such as the United Kingdom, we often take water for granted. In this section, however, you will look at water consumption and how it can be reduced through the use of technology. You will also look at how tables can be used to communicate information and you’ll use some basic mathematics with fractions and percentages to calculate how much water it is possible to save.

Activity 2 Where is water used?

Timing: Allow approximately 5 minutes

In your notebook, write a list of some of the ways water is used today. Do not limit yourself to household use but think of as many environments as possible where water is used.


Water is used the most for washing and cleaning (baths and showers, washing machines and dishwashers, flushing toilets). In addition, water is used in manufacturing industries, in electricity generation and for recreational activities (e.g. swimming pools).
