The Nam Rom irrigation canal system in northwestern Dien Bien province was recognised as a provincial level historical-cultural relic site on May 7.

Built after the Dien Bien Phu victory in 1954 with the purpose of expanding cultivation across Muong Thanh, the region’s biggest field, the irrigation system was the second largest of its kind nationwide at that time.

Construction began in 1963 during wartime and finished seven years later thanks to significant efforts by more than 2,000 personnel, volunteers and locals, 18 of who were killed in action.

Spanning a total distance of 127 kilometres, the main dike took water from the Nam Rom River. Hundreds of kilometres of small canals were then dug to make a complete system.

The Nam Rom project has helped increase the volume of rice production and irrigated area by three times to reach the current 6,000 kilograms per hectare and 6,000 hectares respectively.-VNA
