A trapway is a channel or passage designed to facilitate the movement of water, often found in drainage systems. It helps to direct excess water away from areas where it could cause flooding or erosion. Trapways are commonly used in agricultural fields, urban landscapes, and natural environments to manage water flow effectively. In the context of sewage systems, trapways can also refer to the pathways that allow waste to flow through pipes. These systems are crucial for maintaining sanitation and preventing blockages. Properly designed trapways ensure that both water and waste are efficiently transported to treatment facilities.
