Traditional water supply system for agriculture in Turpan.Xinyu He
Karez system, which is quite similar to the Qanat system, is widely constructed in Turpan Basin, Xinjiang province, China. The word Karez means “well” in local Uyghur language. Turpan Karez system could bring aquifer water from the mountain area to oases in lower part through tunnels. Nowadays, this kind of low tech, autonomous run, energy free approach is gradually abandoned after the appearance of mechanical well. Then, only a few Karez system could generate water because others laking of maintenance.
The water collected by the mother wells of Karez system will distribute to the oases through main tunnel, surface ditches and water retention pond.
The Turpan Karez water system includes not only water collection and transportation part but also the distribution part. This water system plan illustrates the water flows from the outlet of tunnels to the agriculture field. Together with stream, it fed citizens, farmers, plants along ditches, agriculture field, animals and also create cooling living environment.
