 Collectable water from rainfall.  The water that falls on roofs and hard surfaces usually flowing into rivers and the sea and recharging the ground water.  In nature the global average proportion of total rainfall that is blue water is about 40%. 1.1 Blue water

 About 4,000 to 5,000 km3 are annually withdrawn from blue water sources  On average, the rate of withdrawal of blue water has been about two and a half times faster than the rate of population increase during this century.  About 70 % of the total is supplied for irrigation purposes Facts about Blue water

1.2 Grey water  Water from our bathroom, showers, washing machine, etc.  It`s not from the toilet  It is a safe and even benefical source of irrigation water in a yard

 Water transferred back to the atmosphere from soils, natural foliage and rain-fed agriculture.  The United Nations Water Program  Climate change is significantly affecting the availability of freshwater in many regions around the world. 1.3 Green Water

 Pollution that affects our rivers, lochs and wetlands is often characterised in two different forms.  Point source pollution  Diffuse source pollution  Point source pollution can come from sewage treatment works, factories and input from fish farms.  The impacts of pollution can be a loss of biodiversity, as well as adverse effects to our own health. 2.1 Water pollution in Scotland

 Quality of water: 57 th place in the world - measured lakes and rivers - polluted due to farming and industry  Germany’s freshwater is one of the best in the world - drinking water is one of the cleanest all over the world. 2.2 Water pollution in Germany

 All Chinese rivers are polluted to some degree:  Household water  Industrial water  Agricultural Water 2.3 Water pollution in China

 Condition of water bodies  In the last decade the population has decreased 8% and in connection with that the load of domestic wastewater discharged into water has decreased.  Major water pollutants:  Phosphorus  Nitrogen 2.4 In Estonia

 Every day 4500 children die, because they don`t have clean water  One in six human have dirty or polluted drinking water 3.1 Developing Countries

 Diseases:  Cholera  Typhus  Diarrhoea  Hepatitis A and E 3.2 Diseases caused by water Pollution
