Water conduits are structures used to transport water from one place to another. They include ducts, mains, and pipes. Ducts are typically made of metal or plastic and are used to carry water over long distances. Mains are large pipes that are used to supply water to a building or area. Pipes are smaller than mains and are used to connect fixtures such as sinks, toilets, and showers to the main water supply. All three types of water conduits are essential for providing clean and safe water to homes and businesses.
