drainage system
Channels for runoff
A drainage system is a network of channels, pipes, or natural watercourses that carries away excess water or waste.
Cities have storm drainage systems to prevent flooding; buildings have drainage systems to remove wastewater.
The term applies equally to engineered infrastructure and natural watersheds: The Amazon basin is the world's largest drainage system.
