Firstly, water serves the most basic purpose of drinking, without which life is not possible. In the absence of water, one would be unable to clean clothes, utensils, or even take a bath. Farmers depend on water for irrigation. Rainwater is so important for proper agriculture. Water is also used in cooking food. Nowadays water has proved to be a useful source of electricity. Besides human beings, plants require water for their growth. Water is also required for various industrial purposes in factories. In short, no form of life can go on without water.
