The canal uses a bend in the Yongding River to draw water. Its sloped design ensures natural sedimentation, turning silt-laden river water into clean irrigation water.

Nineteen other projects from eight countries were also added to the list, taking the total number of global heritage irrigation sites to 200.

The commission instituted the designation in 2014 to protect and promote irrigation works of historical significance and scientific value.
