in LEDC countries, what are they doing to help improve water access and why is it sustainable?

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)

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)

Before projects are completed

WaterAid makes use of a wide range of water supply technologies. Choices are made based on:

The needs of the communityAvailable water sourcesLocal financial conditionsLocal geographical conditionsLocal availability of materials for constructionLocal availability of labour for constructionLocal availability of spare parts

These are just a few sustainable ways of providing clean water:

Tube-wells and boreholesHand-dug wellsHand-pumpsSpring protectionGravity schemes

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?

Review

Which is the most sustainable method; Large scale (Dams) or small scale (Rainwater harvesting)?
