An ornamental water feature is a decorative structure that uses water to create an aesthetically pleasing effect. The most common type of ornamental water feature is a FOUNTAIN, which is a structure that pumps water into the air in a controlled manner. Fountains can be made from a variety of materials, including stone, metal, and ceramic, and can range in size from small tabletop fountains to large outdoor fountains. Fountains are often used as a focal point in gardens and parks, and can add a calming atmosphere to any outdoor space.
