Drinking water (also known as "potable water") is water that is safe to drink. Many countries impose strict standards governing the quality and purity of drinking water. A great deal of effort goes into processing, transporting and storing water so as to ensure that people have access to a sufficient quantity of high-quality drinking water. This not only costs money, but also consumes a great deal of energy and untreated water.
