TheTurpan water system or Turfan water system (locally called karez water system)
in Turpan, located in the Turpan Depression, Xinjiang, China, is a system adapted by the Turpan people. The Chinese claim the karez system as one of the three greatest water
projects of China, linking it with the Dujiangyan Irrigation System and the Grand Canal.
The karezes are a Persian invention, the word karez means “well” in the local Uyghur language.Turpan has the Turpan Water Museum ( Protected Area of the People’s Republic of China) dedicated to demonstrating its karez water system, as well as exhibiting other historical artifacts.

Turpan’s well system was crucial in Turpan’s development as an important oasis stopover on the ancient Silk Road skirting the barren and hostile Taklamakan Desert. Turpan owes its prosperity to the water provided by its karez well system.
Turpan’s karez water system ismade up of a horizontal series of vertically dug wells that are linked by underground water canals to collect water from the watershed from the base of the Tian Shan Mountains and the nearby Flaming Mountains. The canals channel the water to the surface, taking advantage of the current pro
vided by the gravity of the downward slope of the Turpan Depression. The canals are mostly underground to reduce water evaporation.
In Xinjiang, the greatest number of karez wells are in the Turpan Depression, where today there remain over 1100 karez wells and channels having a total length of over 5,000
kilometres (3,100 mi). The local geography makes karez wells practical for agricultural irrigation and other uses. Turpan is located in the second deepest geographical depression
in the world, with over 4,000 km2 of land below sea level and with soil that forms a
sturdy basin. Water naturally flows down from the nearby mountains during the rainy season in an underground current to the low depression basin under the desert. The Turpan summer is very hot and dry with periods of wind and blowing sand. The water
from the underground channels provides a stable water source year round, independent of season.
IMPORTANCE
Ample water was crucial to Turpan, so that the oasis city could service the many caravans on the Silk Route resting there near a route skirting the Taklamakan Desert. The caravans included merchant traders and missionaries
with their armed escorts, animals including camels, sometimes numbering into the thousands, along with camel drivers, agents and other personnel, all of whom might stay for a week or more. The caravans needed pastures for their animals, resting facilities, trading bazaars for conducting business, and replenishment of food and water.
