Water is used by us for various purposes. Water is used for drinking. The human body depends on water for survival. Water is used for cooking food too. The water that we need for consuming must be clean, potable water. If humans use dirty or contaminated water for these purposes they can fall sick and die from the diseases. Therefore, for good health we need clean drinking water to be available for our use. Water is also needed for farming. We also use water to maintain personal hygiene. We also need water to wash our clothes, as also to keep our homes and surroundings clean.
