Tap water
Tap Water
Tap water (pronunciation: /tæp ˈwɔːtər/), also known as municipal water or running water, is water supplied to a tap (also known as a faucet) inside the built environment.
Etymology
The term "tap water" is derived from the simple fact that it is water available on demand by opening a tap. The word "tap" comes from the Old English taeppe, meaning "tap, faucet, or spigot", while "water" comes from the Old English wæter.
Definition
Tap water is typically sourced from water bodies such as rivers, lakes, reservoirs, or underground aquifers. It is then treated and purified at a water treatment plant to meet government standards for safe drinking water. The treated water is then distributed through a network of pipes, known as a water supply network, to homes, businesses, and other buildings.
