Iran has 36,300 active Qanats with a total length of 274,000 km (according to the book, the Persian Qanats by H.A Volf). If you want to understand the magnitude of this number, compare it with the length of the wall of China or the diameter of the planet earth: the length of the Persian Qanats is 43 times more than the length of the China wall, and equals to 18 times the Earth's diameter (14,663 km), symbolizing sustainable development and management and fair dividing of water resources. The number of qanats in Iran alone is more than the total number of qanats available in other countries. The wonders of the technology of the Qanats and their usefulness in protecting the environment led to the registration of 11 qanats from the most unique Persian Qanats in the UNESCO World Heritage List, one of them is Qanat of Baladeh in Ferdows, which probably dates back to the Sassanid period, and even Nasser Khosro attributed it to KeyKhosrow. The Qanats of Baladeh has 16 active qanats (totaling 27 fields) and has two springs, and its water flows into a big stream. This big stream that is divided into two smaller stream, runs 35 kilometers and, along its path, irrigates agricultural land and numerous gardens in the Ferdows plain. One of the most interesting innovations used in the Qanat of Baladeh in Ferdows was to Puddle the water along the paths to prevent the water from penetrating into the ground and the loss of water (the person who was responsible for puddling the water, was known as Tirehgar). Because the volume of water of this qanat was very high, they drove it into two different parts, and chose someone as Kial (water dividers), taking full pay and expenses, as a full-time employee, to do that. Over half of the income money of the Qanat of Baladeh water has been endowed, and this shows the generosity of the desert people in spite of the difficulties of life.
