What Is a Water Well?

Water well, an engineering structure mainly used for mining groundwater. It can be vertical, oblique and a combination of different directions, but generally it is mainly vertical, which can be used for daily water intake, irrigation, and also used to avoid hiding or storing things.

Water wells are of great significance to the development of human civilization. Before the emergence of water wells, humans lived by water and could only live in places with surface water or springs. The invention of water wells expanded the scope of human activities. China is one of the earliest countries in the world to develop and use groundwater. The earliest wells discovered in China are Yuyao, Zhejiang

Kaner Well

China's Kan'er well, cleverly adapted to the natural conditions of the piedmont zone in arid regions, can not only reduce water evaporation, but also facilitate water intake and transportation. It includes underground corridors and a series of shafts. The part of the bottom of the underground corridor that is lower than the groundwater level is used to intercept the underground subsurface flow, and the part that is higher than the diving level is used for water transportation. The vertical shaft is used for excavation and ventilation when the underground corridor is excavated, and it is used as a channel for water intake and maintenance. At the exit of the underground corridor, a reservoir is often built. The length of a single Kaner well can reach dozens of kilometers. There are still 2,000 Kaner wells in use in Xinjiang, China.
