![Page 2: Water management in the UK. Learning objectives All of you will be able to describe what water stress, surplus and deficit are Most of you will be able.](https://reader034.fdocuments.net/reader034/viewer/2022051819/5517b3ec55034645368b6052/html5/thumbnails/2.jpg)
Learning objectives
• All of you will be able to describe what water stress, surplus and deficit are
• Most of you will be able to describe and explain water stress, surplus and deficit and to name an example
• Some of you will be able describe and explain the above terms in greater detail, using a case study to support your answer in talking about how to manage water sustainably

What do we use water for?
• You have 1 minute in pairs to come up with as many different ways we use water as you can.

KEY TERMSWater stress: this occurs when the amount of water available does not
meet that required. This may be due to an inadequate supply at a particular time or it may relate to water quality.
Areas of deficit: locations where rain that falls does not provide enough water on a permanent basis. Shortages may occur under
certain conditions. e.g. long periods without rain
Areas of surplus: areas that have more water than is needed – often such areas receive a high rainfall total, but have a relatively small
population.

Household water use in England and Wales
![Page 8: Water management in the UK. Learning objectives All of you will be able to describe what water stress, surplus and deficit are Most of you will be able.](https://reader034.fdocuments.net/reader034/viewer/2022051819/5517b3ec55034645368b6052/html5/thumbnails/8.jpg)
Why will the demand for water increase over time?
• Increase in population• Increase in number of households• Increase in use of time-saving goods e.g.
washing machines, dishwashers• Buying more foodstuffs out of season

Trends in total water demand - 2008 to 2050 (England & Wales)
![Page 12: Water management in the UK. Learning objectives All of you will be able to describe what water stress, surplus and deficit are Most of you will be able.](https://reader034.fdocuments.net/reader034/viewer/2022051819/5517b3ec55034645368b6052/html5/thumbnails/12.jpg)
How can demand be met in a more sustainable way?
• Increased awareness e.g. houses with a water meter use on average 19l less per person per day
• More efficient house designs• More efficient toilet systems• Water butts• Recycling water within the house (e.g. bath water for
flushing toilets)• More showers than baths• Leakage is a big problem (water authorities)

Location of Kielder Water Reservoir, Northumberland. A water storage and transfer scheme
![Page 14: Water management in the UK. Learning objectives All of you will be able to describe what water stress, surplus and deficit are Most of you will be able.](https://reader034.fdocuments.net/reader034/viewer/2022051819/5517b3ec55034645368b6052/html5/thumbnails/14.jpg)
Kielder Water – reservoir and water transfer case study
• READ through case study• Create your own case study containing the following:• Location (map showing location including key rivers,
towns, reservoir and transfer – see map on case study hand out)
• Why was it located there? (at least 5 points on the reasons for locating it where it is)
• Timeline and icon sketches• Impacts/effects – sort facts into groups and again
into order of importance.
