👉 A drainway is a type of canal or channel that is designed to transport water and other substances from one location to another. It typically has a narrow, straight shape and is built over land or on top of ground level. Drainways can be man-made or natural, depending on the purpose for which they are constructed. Drainways are essential for maintaining water quality in urban areas, as they help prevent pollution by filtering out pollutants like sewage, chemicals, and nutrients from runoff into bodies of water
