An artesian well is a natural underground water source that flows to the surface due to pressure from a confined aquifer. Synonyms for artesian well include artesian spring, artesian borehole, and artesian fountain. These terms refer to the same type of water source that is accessed through a drilled hole in the ground. In some regions, artesian wells are also referred to as flowing wells or bore wells. Regardless of their name, artesian wells provide valuable water resources to communities and farmers in many parts of the world. They are often considered a sustainable source of water because they are replenished naturally.
