We live on a water planet. About 71% of Earths surface is covered by water. It has many unique properties and a most vital natural resource for all life forms on Earth. Water, the life blood of the ecosphere has played an important part in determining where people can live happily. Without water there is no survival and water is used for various purposes. Water is constantly available by the hydrological cycle where the water evaporates as vapor from oceans, lakes and rivers and then condenses as rain. This cycle has helped in the availability of water throughout the year.
Different Uses of Water Explained
The two common measures of human use are withdrawal and consumption. The main source of water is the ground water and the surface water. About 60% of the water withdrawn is consumed for various purposes worldwide. The most important usages of water are the following.
Average, globally about 69% of the water withdrawn every year is used for irrigation. Nearly, 70-80% of water evaporates or seeps into the ground before it reaches the crops. The percentage of water used by various countries for irrigation is Asia-82%, Africa-69%, United States- 41% and Europe-30%
Water is the life source of all living beings. It is used for domestic purpose which includes the everyday chores of a home, such as drinking, cooking, bathing, washing clothes and dishes, toilets, watering garden, etc.
Water is used in the production of electric power. Electricity is produced by turning a turbine using the steam power. Then the steam is condensed back to water by cooling it, where the cycle begins again.
Water is used for commercial purpose which includes fresh water for hotels, restaurants, office buildings, etc. Industrial water is used for processing, cleaning, transportation, dilution, cooling in manufacturing industries. Industries like steel, chemical, paper and petroleum are the major usage of water. The saline water taken from the surface water is used for cooling generators in thermoelectric power plants. It is also used in industries and mines to cool machinery and to wash transport products.
The livestock water which is a source of fresh water is used for animals, diaries, fish farms, etc.

Different Uses of Water-conclusion
Water the life-blood of all living beings is a wonderful gift of the almighty. It is our duty to preserve this precious natural resource. Without water there is no survival. Growth in the population rate and industries has led to water shortage. As a result of global warming, changes have occurred in the rainfall pattern and have disrupted the water supplies. If this situation continues, it would be difficult for survival, measures should be taken to prevent water pollution and preserve water.
