It is to be remembered that it was water that determined the location of human settlements and without the Nile the Egyptian Civilization would not have developed The Nile provided the Egyptians facilities for irrigation and transport.

The urban man rarely thinks of the importance of water. When he needs water, all he has to do is to turn on the tap. The only time the urban folk become aware of the importance of water is when there is a drought and their water supply is regulated. If water rationing becomes too drastic. they may find themselves in a worse position than the rural man who may have a steady supply of water from his well.
Imagine a day when the taps ran dry: Mr. Townsman would have found life intolerable. He could not brush his teeth, have his shave or could he have his bath in the morning. After lunch, he would have had a very difficult time trying to wash up. He might have used cloth to wipe his crockery. He could not wash his car. At the end of the day, however, our Mr. Townsman would have realized that water is precious and he should not be a water-waster.
Scientists find water the most fascinating fluid in the world because of its versatility and usefulness. Electricity is generated by the force of running water. Unlike other substances, water expands when freezing takes place. In ancient Rome snow was used to pack prawns and meat. Ice is used for refrigeration.
