catchment area
Water collection zone
A catchment area is the region from which something draws its population or resources.
A hospital's catchment area is the surrounding territory whose residents it serves; a school's catchment area determines which children may enroll.
The term comes from water management, where it means the land area draining into a river or reservoir.
The clinic serves a catchment area of about fifty thousand people.
