How would you describe water quality and distribution in a few words?
Water is essential for life – it is used for drinking, cooking, cleaning, and more. Water quality is the measure of how safe and clean it is. It is monitored by experts in many places. Water distribution is the process of getting the water to the places it is needed and used.
Water Quality and Distribution
Water Quality: The degree to which water meets standards for drinking, irrigation, and other uses. Water Distribution: The delivery of water from its source to a point of use. Water Cycle: The continuous movement of water from the land to the atmosphere and back to the land in the form of precipitation.
Approximately 78% of the Earth's surface is covered in water, but only 2.5% is fresh water and only 0.3% is accessible for human use. In most of the world, water is distributed through a network of pipes that are made up of concrete, steel, plastic, and copper. The Netherlands have the most advanced water distribution system in the world, with a network of over 150,000 kilometers of pipes!
