 4L water to produce one bottle of beer.
 500L water to produce 1 orange.
 1,340,000 million L to produce on tonne of steel,[object Object]
What is water Efficiency? The United States Environmental Protection Agency describes water efficiency as: “the long-term ethic of saving water resources through the employment of water-saving technologies and activities.” Who is responsible for it? Each and every individual From top down
Why be Water Efficient? Worldwide water consumption up ten fold since 1900 By 2040 population up by 45% At present, 1 third of the worlds population facing water shortages and poor drinking water quality
