4. Water Saving Methods
 There are many ways of saving water
 Read through the information about different
methods
 Put into 3 categories.
 Domestic
 Industrial
 Agricultural
 Check them and stick them into your
books under the correct headings

6. Stick this in you books and label the different
ways houses in HICs can save water.

7. Case Study: Walkers Crisps
 Walkers Crisps have reduced its usage by
50%
 This is saving over 700,000,000 litres a
year
 They did this by:-
 Installing 30 water meters at their factories,
allowing them to monitor where and when water was
being used
 They recycle the water from one part of the
production, rather than wasting it
 They educated their staff about using water
sensibly
 They assigned ‘water champions’ and ‘leak busters’
to each shift.
 It was VERY successful!

8. Extension
 Can you think of any water saving methods you
could use in your home
 It could be new designs for old products,
 -or-
 New methods of saving water

9. Specification detail
 5.3b The management of water resources (a dispute
between countries, areas or within a country over
water transfer).

10. How can water cause conflict?
 Conflict over water in the Middle East and
the Zambezi basin : here

11. Map work
 Use a map and find two countries that share the
same water source.
 Research this water source and discover if there is
any conflict.
