( Quang Ngai Newspaper) - To ensure irrigation water for the 2024-2025 winter-spring crop, specialized sectors and local authorities mobilized people to participate in dredging eroded, buried, and silted canals. At the same time, resources were focused on repairing, overcoming, and constructing irrigation works (CTTL) damaged in recent floods.
Proactively overcome
At the end of November 2024, officers and employees at the Branch of Irrigation Management Station No. 3 - Tu Nghia (Quang Ngai CTTL Exploitation One Member Co., Ltd.) started dredging and clearing canal banks; removing trash and duckweed, water spinach at dams and drainage culverts to clear the flow. Head of the Branch of Irrigation Management Station No. 3 - Tu Nghia Phan Sau said that the unit is managing 1 reservoir, 3 dams, 18 canals with a length of over 70km and 623 works on the canal, ensuring irrigation water for nearly 9,000 hectares of rice and crops in Tu Nghia district each year. For the 2024 - 2025 winter-spring crop alone, the unit has signed contracts with 22 agricultural service cooperatives in localities, providing irrigation water for more than 4,300 hectares of agricultural land.
Since the beginning of October, the unit has inspected the current status and reinforced and repaired some minor damages at the CTTL and canals. However, the most worrying thing is that the drainage culvert of the N-VC16 canal section through Nghia Ky commune (Tu Nghia) has been eroded and cracked, affecting the water supply to serve nearly 200 hectares of rice fields in Nghia Ky commune and Quang Phu ward (Quang Ngai city). In addition, the culvert across the road of the N-VC16-2 canal, through An Hoi Nam 1 village, Nghia Ky commune, has been eroded and damaged, affecting the water supply to serve more than 45 hectares of rice fields of the people.

Meanwhile, local authorities in the province are also mobilizing forces to dredge and clean canals, and repair fields that have been damaged by flooding. Especially in Minh Long and Nghia Hanh districts, 18 temporary dams and weirs were damaged, washed away, and 4 pumping stations were deeply flooded due to the impact of heavy rain from November 22 to 24. In addition, local authorities are also urging units to speed up the progress of repairing and building new irrigation works and canals. For example, at the N10-2-2 canal, through Phuc Minh village, Hanh Thuan commune (Nghia Hanh), units are making efforts to construct a drainage culvert to clear the route (more than 650m long), ensuring irrigation water for nearly 30 hectares of agricultural land in the winter-spring crop of 2024 - 2025. Along with that, the Department of Agriculture and Rural Development of Nghia Hanh district also organized inspections, organized repairs and proposed repairs of 6 CTTL and 7 canal routes, with a length of more than 5.2km.
According to Phan Cong Huan, Head of the Department of Agriculture and Rural Development of Nghia Hanh district, to ensure irrigation water for the 2024-2025 winter-spring crop, the Department of Agriculture and Rural Development proactively coordinates with local authorities to mobilize people to dredge and clean canals and organize reinforcement and temporary repair of damage. For dams and canals buried by rocks and soil, mobilize local people to clean up mud, rocks, and clear the flow. For broken or collapsed canal sections, temporarily install water pipes. Areas without proactive water supply will switch to growing short-term crops, ensuring compliance with the crop time frame.
Need support
Quang Ngai CTTL Exploitation One Member Co., Ltd. is currently managing and exploiting 24 reservoirs, 33 dams, saltwater prevention dams and pumping stations, 87.6km of main canals and 674km of branch canals, ensuring an irrigation area of over 46,000 hectares/year, of which the winter-spring crop is about 24,000 hectares. Therefore, since the beginning of October, the company has focused on inspecting and assessing the level of damage, in order to proactively handle temporary landslides, reinforce canal banks, and dredge silted canal beds. At the same time, it regularly coordinates with local authorities to mobilize people, forces and means to salvage obstacles, duckweed, and garbage at drainage sluices, saltwater prevention dams, and dams... Thereby, both ensuring the flow of water, leading water to serve the production season, and draining floods to ensure the safety of the works.

However, the heavy rain from November 22 to 24 has caused many CTTLs and canals in the province to be seriously damaged and silted up, affecting the water supply capacity for production, such as: North main canal, South main canal, South main canal of Ve river belonging to Thach Nham irrigation system; Hoc Xoai main canal, Nghia Thang commune (Tu Nghia); B3-2, B4-2 canals and N-VC16 drainage culvert; Nui Ngang main canal, An Tho main canal... In addition, a series of CTTLs and canals managed by Quang Ngai CTTL Exploitation One Member Co., Ltd. were also seriously damaged and degraded, especially Khe Hoa saltwater retention dam (Quang Ngai city) and Hien Luong (Tu Nghia) which had many items broken, washed away by water causing water leakage. This not only causes unsafe construction, but also leads to the risk of saltwater intrusion, not ensuring the goal of storing fresh water for agricultural production and daily life of people in Nghia Ha, Tinh Khe communes (Quang Ngai city) and Nghia Hoa (Tu Nghia).
Director of Quang Ngai CTTL Exploitation One Member Co., Ltd. Ha The Vinh said that currently, 25 CTTLs and large canals managed by the unit are severely damaged, affecting the supply and conduction of water for production sectors. However, because the cost of repair and restoration is large, the company reported to the Department of Agriculture and Rural Development, proposing that the province pay attention to support, initially 3.7 billion VND for regular maintenance and repair of CTTLs and canals in 2025. In particular, early allocation of funds (over 130 billion VND) to implement the Project to repair and solidify the system of canals, dams, contributing to ensuring safety in operation and water regulation, serving irrigation water for production and daily life of the people.
