Qanat
A qanat is an underground tunnel that brings groundwater to the surface without a pump. It starts at a deep mother well at the foot of the mountains, where there is plenty of groundwater, and runs with a gentle downward slope to a village, where the water comes out. A line of wells from the surface to the tunnel let the diggers lift out the earth and let air in. People in Iran have dug qanats for thousands of years.
