Proactively review and evaluate the current status of irrigation works to develop timely treatment plans with the motto of "being one step ahead". These are solutions that the Department of Agriculture and localities in the province focus on implementing, in order to ensure production and safety for people in the face of complicated weather developments.
Tien Yen district currently has 16 dams; 57 bridges/spillways distributed in 7 communes; more than 42.4 km of level IV and level V dykes. According to district statistics, storm No. 3 affected 68 irrigation infrastructure works in the district. Immediately after the storm, the district reviewed the entire system of dykes, reservoirs, and spillways in the area; promptly proposed repair plans and arranged funding sources to ensure safety for people, crops, production facilities, etc.
Ms. Do Thi Duyen, Head of the District Department of Agriculture and Rural Development, said: The cost of overcoming the consequences of the storm on the district's irrigation system is more than 54 billion VND. Up to this point, many items have been completed, and the repair work is still being urgently accelerated for damaged dike works. The district's dam system has not been much affected. However, the district leaders always emphasize the spirit of not being subjective because extreme weather events are becoming increasingly unpredictable.
In addition to reviewing, reinforcing, and protecting existing irrigation works, the district is also proactive in completing irrigation infrastructure in the following years. The District People's Committee has proposed a list of projects for the Agriculture and Rural Development sector to include in the medium-term public investment plan, requesting the provincial budget to support the 2024-2025 period with the Cai Gia reservoir dam construction project (Hai Lang commune); the 2026-2030 period with the Binh Son Reservoir Project (Dong Ngu commune); and the Ha Trang Tay village dike upgrade project (Dong Hai commune).
According to the leaders of Tien Yen district, currently, the water source for production and livestock activities in Dong Ngu and Dong Hai communes is mainly from Ha Thanh river and some small streams. Some small irrigation works have been invested by the district, but they have not yet met the people's needs for agricultural production, aquaculture and domestic water supply; there are no reservoirs to store water during the rainy or dry season, causing many difficulties for socio-economic development in the area. Therefore, these are important and urgent works for people's lives, production and socio-economic activities; ensuring clean water for people's daily life, limiting natural disasters and floods in the commune; meeting the water source for future industrial production activities in industrial parks and export processing zones planned for construction in Dong Ngu and Dong Hai communes.
The province currently has 188 dams and reservoirs with a total designed capacity of 359 million m3. After storm No. 3, the agricultural sector and localities have been quickly implementing plans and solutions to maintain and upgrade the works. In particular, Yen Lap Lake located in Quang Yen town is the irrigation project with the largest storage capacity in the province with 127.5 million m3 of water.
Mr. Bui Duc Viet, Head of Construction Supervision Department, Yen Lap Irrigation Company Limited, said: Although not affected by storm No. 3, the infrastructure of Yen Lap Lake still needs to be upgraded to cope with extreme natural disasters. The company has proposed installing some additional rain gauges in the circulation basin to combine with the radar system, thereby warning the most accurate amount of water flowing into the lake, and having a more reasonable flood spillway regulation plan. In addition, research is being done to adjust and repair 1 dam into a free spillway to support the flood spillway of Yen Lap Lake in case of increased flood levels.
Meanwhile, many dikes in the province, after being upgraded, have now increased their ability to withstand storms to level 9, the rest can withstand storms from level 6-8. Ha Nam dike (Quang Yen town) is the only dike in the province that meets the standards of level III, capable of withstanding storms of level 10. According to Mr. Doan Manh Phuong, Head of the Irrigation Sub-Department, in the face of increasingly severe natural disasters, the provincial leaders have agreed to the policy of developing a Project to Improve the Safety of the Provincial Dike System, to proactively respond to super typhoons like Yagi in the future. The Provincial People's Council has also issued a resolution on dike maintenance and urgent handling of dike incidents every year. This is the basis for localities to develop plans and solutions suitable to their own characteristics, allocate resources, upgrade and complete the infrastructure system, natural disaster prevention works, protect property and ensure the safety of people's lives.
