The CaiLon - CaiBe irrigation system includes three sluices: one on the CaiLon River, one on the CaiBe River, and the Xeo Ro sluice in Chau Thanh and An Bien districts, Kien Giang province, Vietnam. This is currently the largest irrigation project in Vietnam in terms of scale and water flow capacity, responsible for controlling saline, freshwater, and brackish water to facilitate production models based on the ecosystem for an area of 384,120 hectares in Kien Giang, Hau Giang, Soc Trang, Bac Lieu, and Ca Mau provinces. Establishing norms and cost items as a basis for completing the organizational structure of the unit that will be assigned to manage and exploit the project is essential for allocating labor and material costs.
