👉 Drippage is a phenomenon in which water flows from an open surface into a closed container, often a pipe or tank. This occurs when the surface that receives the water is not sealed properly, allowing air and other contaminants to enter the container. In terms of hydrology, drippage can refer to the flow of rainwater through a closed system such as a roof or drain line. It's also common in industrial processes where waste water from machinery or equipment flows into pipes or tanks for treatment
