Soc Trang - The operation of Rach mop boat lock contributes to responding to drought and salinity in 2025, ensuring fresh water for production and daily life.
After 2 years of urgent construction, the Rach mop boat lock under the Hau River South Bank Water Control Project has officially met the conditions to prevent salinity for the 2025 dry season.According to information from the Irrigation Investment and Construction Management Board 10 (Ministry of Agriculture and Rural Development), the project has completed 92.16% of the volume and is in the testing phase. It is expected that the entire project will be completed and handed over for use before April 30, 1 month ahead of schedule.Mr. Kieu Van Cong - Deputy Director of the Irrigation Investment and Construction Management Board 10 - said that the main items such as culverts and boat lock gates have been completed, ensuring effective salinity control in the coming time. The construction unit has arranged teams and teams to directly supervise the project, especially focusing on the mechanical construction team of the gate to ensure the highest technical quality.For waterway traffic, when the culvert is put into operation (closed), ships will travel through the 15 m wide boat dock. The closed boat dock is made of hydraulic cranes, ensuring safety and convenience for vehicles to pass.Rach mop boat lock has an investment capital of more than 500 billion VND. This irrigation project is located on the Rach mop River (about 500 m from the Hau River) bordering Nhon My Commune (Ke Sach District) and Song Phung Commune (Long Phu District, Soc Trang Province).The culvert has a drainage width of 85m. Including 2 sewer compartments, each compartment is 35m wide, 1 boat dock compartment is 15m wide.The gate of the Rach mop boat lock valve is made of steel, sealed and opened with a hydraulic silk clutch, the culvert has an automatic monitoring and supervision system.When the salinity in front of the sewers is >2g/liter, the valve gate will be closed to prevent salinity from penetrating deep into the field.Mr. Tran Van Lau - Chairman of Soc Trang Provincial People's Committee (2nd from left) said that the situation of saline intrusion in the dry season of 2024-2025 in the province has appeared since mid-January 2025. On the Hau River, the salinity level of 4g/liter was recorded during high tides moving deep into the inland area from 35-40km. Therefore, the operation of the Rach mop boat lock valve is of great significance in responding to saline intrusion, creating stable production and living conditions for people in the area.Along with the Rach mop boat lock, the Southern Hau River Water Control Project also has other small culverts (Muong Khai 2, Tra much, Cai Trung, Cau Truong, Tra Quyt) being implemented, with a total cost of 900 billion VND.The goal of the project is to control salinity, high tides, keep sweeteners, respond to saline intrusion, protect 19,220 hectares of production areas in Soc Trang province and minimize damage caused by drought and salinity for more than 36,710 hectares on the southern bank of the Hau River of the two provinces of Soc Trang and Hau Giang.
