2 unusual facts about Qanat


Jasb Rural District

The valley itself is fed by the solitary Azna river which receives most of its water from the runoff of surrounding Qanats; the valley is surrounded by mountains which form a U-Shaped range, the highest peak is the Kuh-e-Velijeya rising to 3233 metres (10604 feet).

The first structures were built close to the Qanats so that there would be a constant water supply to the fields and for household use, as the villages grew in size the construction of buildings occurred on stone built terraces, which sloped sharply towards the river, since the river could flood quickly during heavy rains much time and labour was devoted to the maintenance of damaged terraces.
