The waterwheels have become an iconic image which is commonly seen in villages of the Thai ethnic group in the mountainous areas.
They work as an automatic pump with a giant wheel that works day and night to take water from the lower rivers or streams to the higher fields.
Thai ethnic people in Nom Village join hands to construct a new waterwheel before the beginning of a new rice planting season.
The nearly 80 waterwheels spinning along the two banks of Nam Hua Stream have not only contributed to bringing a bumper rice season to Nom villagers but also created a beautiful and poetic image for visitors to admire and explore.
