The Persian Qanats

Qanat is a ditch or canal dug underground to let water reach the surface. It is consist of vertical access shafts, cut cones and canals in the depth of the earth. In fact it connects a series of well originating from the aquifer. Aquifers are usually water tables and the use of Qanats is guiding and maintaining water for agriculture and other uses.

The technology of Qanat

The technology of Qanat was developed in the early first millennium BC in the arid mountainous regions of Iran. This technology enabled the farmers in these regions to farm in long periods of drought where they couldn’t find surface water. Gradually, these Qanats began to become popular in other parts of the world. And now there are many Qanats in China, Morocco, and even on the America continent.

In fact, ancient people of the Persia had come up with this innovation several thousand years ago. And after a while, they named it Kariz or Kahriz. The first and the longest Qanat in the world exist in Iran. By employing this invention, which has been unique in the world, it is possible to collect a considerable amount of groundwater and transmit it to the surface. As a result, it works like a natural spring; water flows out of the ground all year without any help. Besides, this innovation brought about making “water clock” and “watermill” with itself. Although it’s been invented for thousands of years, it’s still a conventional method for obtaining water in some villages of Iran. It is even the main pillar of agriculture in arid areas across the country.The Persian Qanats
