In Marrakech and the Haouz plain, the qanats have been abandoned since the early 1970s, having dried up. This space was needed to remove excavated material and to provide ventilation and access for future repairs. Beneath Iran's Dusty Desert Lie Ancient Water Tunnels Still in Use. One of the longest known qanats in the world that is 70 km long is located in Iran. [11] Alternative terms for qanats in Asia and North Africa are kakuriz, chin-avulz and mayun. There is evidence that as early as the second half of the 5th century BCE water brought in qanats was being used. The system can be clearly traced up to Ibrahim Roja. For example, Mohammad bin Hasan quotes Aboo-Hanifeh that in case someone constructs a qanat in abandoned land, someone else can dig another qanat in the same land on the condition that the second qanat is 500 zera’ (375 meters) away from the first one.

[69], In an August 21, 1906 letter written from Teheran, Florence Khanum, the American wife of Persian diplomat Ali Kuli Khan, described the use of qanats for the garden at the home of her brother-in-law, General Husayn Kalantar,[70] 7 6 2 5 5267.

The foggara is dug into the foothills of a fairly steep mountain range such as the eastern ranges of the Atlas mountains. There are three types of Falaj: Daudi (Arabic: داوودية‎) with underground aqueducts, Ghaili (Arabic: الغيلية‎) requiring a dam to collect the water, and Aini (Arabic: العينية‎) whose source is a water spring.

The study says that a single karez has the potential to provide enough household water for nearly 9,000 individuals and irrigate over 200 hectares of farmland. The qanat should not be confused with the spring-flow tunnel typical to the mountainous area around Jerusalem. The Persian Qanat — The Underground Water Transport System The civilization of Persia (Iran) was one of the most flourishing that existed for thousands of years and, beyond art, left us a culture and several techniques, to improve the cities, worthy of admiration. Qanat is an ancient Persian technology for moving water over long distances underground. [28], Traditionally qanats are built by a group of skilled laborers, muqannīs, with hand labor.

Then, the secondary wells connected the tunnel with the surface and finally, irrigation channels carried the water to respective areas. Later, the qanats gradually spread, and many of them are continuously in use stretching from China on the east to Morocco on the west, and even to both American continents.
