Our Mission

The karez system, an irrigation system connected by underground channels, is considered as one of the three great ancient projects in China. The other two being the Great Wall and the Grand Canal . There are nearly one thousand karez totaling five thousand kilometers in length in Turpan.

The structure of the karez basically consists of wells, underground channels, ground canal and small reservoirs. In spring and summer, a great amount of melting snow and rainfall flow down from the Bogda and Karawuquntag mountains north and west of the Turpan depression into the valleys and then seep into the Gobi desert. Taking advantage of the mountain slopes, the working people ingeniously created the karez to draw the underground water to irrigate the farmland. The water in the karez will not evaporate in large quantities even under the scorching heat and fierce wind, hence ensuring a stable water flow and gravity irrigation.

坎儿井 - karez 是与横亘东西的万里长城、纵贯南北的大运河齐名的中国古代三大工程之一,是伟大的地下水利灌溉工程。它早在2000年前的汉代就已经出现雏形,以后,随着丝绸之路的发展,逐渐向西传到中亚和波斯。 
坎儿井利用地面坡度引取地下水自流灌溉。据统计,吐鲁番盆地有水坎儿井1237条,实际使用的853条,总长度超过5000公里,总出水量每秒约10立方米。坎儿井由坚井、地下暗渠、地面明渠、涝坝四个部分组成。竖井最深的在90米以上。一般长3-8公里,最长的达10公里以上,年灌溉300亩,最好的年灌溉可达500亩。
