1. Intermediate solutions

2. Connector
Think of a question you are going to ask someone about large scale water projects.

3. By the end of the lesson:
All pupils will be able to describe the work
of wateraid
All pupils will be understand the different
Projects that exist
All pupils will be able to explain a how an
Intermediate project is sustainable.

4. Homelearning
Complete exam question Using examples , explain how water use could be made more sustainable (4)

5. The vision
Vision
WaterAid's vision is of a world where everyone has access to safe water and sanitation.
Mission
WaterAid transforms lives by improving access to safe water, hygiene and sanitation in the world's poorest communities. We work with partners and influence decision-makers to maximise our impact.

6. Where do they work?

7. Video 2
Watch the video
Take notes on the problems faced by people in LEDC countries, what are they doing to help improve water access and why is it sustainable?

8. Facts
884 million people in the world do not have access to safe water. This is roughly one in eight of the world's population. (WHO/UNICEF)
2.6 billion people in the world do not have access to adequate sanitation, this is almost two fifths of the world's population. (WHO/UNICEF)
1.4 million children die every year from diarrhoea caused by unclean water and poor sanitation - 4,000 child deaths a day or one child every 20 seconds. This equates to 160 infant school classrooms lost every single day to an entirely preventable public health crisis. (WHO/WaterAid)

9. What has water-aid done?
Since 1981, we have reached 15.89 million people with safe water 
Since 2004, we have reached 11.02 million people with sanitation
In 2010/11 we reached 1.45 million people with safe water and 1.62 million people with sanitation.
Just £15 can enable one person to access a lasting supply of safe water, improved hygiene and sanitation. (WaterAid)

10. Before projects are completed
WaterAid makes use of a wide range of water supply technologies. Choices are made based on:
The needs of the community
Available water sources
Local financial conditions
Local geographical conditions
Local availability of materials for construction
Local availability of labour for construction
Local availability of spare parts

11. These are just a few sustainable ways of providing clean water:
Tube-wells and boreholes Hand-dug wells Hand-pumps Spring protection Gravity schemes

12. What is intermediate technology?
Using the ‘water aid’ sheet provided and you’re the text book; annotate how this intermediate technology works. Underneath explain why is sustainable?

13. Rainwater harvesting

14. Review
Which is the most sustainable method; Large scale (Dams) or small scale (Rainwater harvesting)?
Stand at the front of the room if you think Large scale
Stand at back of room if you think small scale
