The human body is more than three-quarters water. Water is essential to existence, not only for people but for plants and animals as well.

Water, when evaporated from the world's oceans by the heat of the sun, leaves its salt behind. Winds blow moisture inland where clouds are formed and some of the water falls to earth as rain or snow. Then, by one route or another, it returns to the ocean.

In the Denver area, approximately 500 gallons per day per household are used, and an average of 150 gallons per house hold are used before breakfast. The average daily use in Canada is 1,090 gallons per person, in Australia it is 876, in Great Britain 185 gallons and in Switzerland they only use 77 gallons per person per day.
