Potable water, also known as drinking water, is safe for drinking and food preparation use. Potable comes to the English language from the Latin word potabilis which means drinkable. In order for potable water to be consumed or used, it must travel from its originating source via a transmission main to a treatment plant where it is treated and then sent through distribution lines including valves, hydrants, fittings and finally through other appurtenances delivering water to the end user.
