Accompanying the delegation were representative leaders of the Office of the Provincial People's Committee; the Departments of: Agriculture and Environment, Construction, Finance; the People's Committees of My Thai and Xuan Cam communes; the Drainage and Wastewater Treatment Center; Bac Song Thuong Irrigation Works One Member Limited Liability Company, Nam Song Thuong Irrigation Works One Member Limited Liability Company along with consulting, construction, and equipment installation units.
In Tan Tien ward, Vice Chairman of the Provincial People's Committee Le Xuan Loi and the working delegation inspected the discharge culvert through the dike of Van Son pumping station, checking the culvert body, water chute, stilling basin, river-side dike slope, and the discharge canal area. At the same time, they listened to the management unit and specialized agencies report on the current status, causes of the incident, and implemented solutions.
The discharge culvert of Van Son pumping station was located at K15+930 of the left Thuong dike. After storm No. 3 in 2025, the dike slope area adjacent to the river-side wing wall experienced subsidence and slumping; the contact position between the culvert body and the drainage chute was subsided, cracked, and displaced, threatening the flood control safety of the dike line. The Ministry of Agriculture and Environment once requested to identify this as a critical dike position, build a protection plan, and closely monitor the developments of the incident.

After treatment, the reinforced positions had not shown further subsidence or leakage; the pumping station was allowed to operate again to serve drainage against waterlogging. However, these solutions only ensured immediate safety. In the long term, the project would need an overall survey and evaluation to complete the outer bank of the discharge canal, extend the culvert body, widen the dike cross-section, rebuild the water chute and stilling basin; at the same time, regulate the downstream channel, reinforce the river-side dike slope, and areas directly affected by the flow.
Through practical inspection, Vice Chairman of the Provincial People's Committee Le Xuan Loi requested specialized agencies and the management unit to accurately determine the scope and level of impact of the incident on the dike line and the operation capability of the pumping station; on that basis, propose synchronous technical solutions with long-term stability and sustainability.
He noted that Van Son pumping station was an important drainage hub of the area. Therefore, the treatment plan must both ensure dike safety and maintain drainage capacity in heavy rain situations. The operation of the station must be associated with a strict inspection and monitoring regime, clearly assigning the responsibilities of each agency, unit, and individual.
During the period when long-term solutions had not been implemented, the Drainage and Wastewater Treatment Center must regularly monitor the current status of the project, especially when operating drainage pumps or when the river water level fluctuates; fully prepare forces, materials, and means to handle immediately from the first hour if unusual signs were detected.
The Vice Chairman of the Provincial People's Committee requested to urgently complete the dossier proposing the investment policy for the Project to renovate and upgrade Van Son pumping station, ensuring the safety of dike works, and improving the drainage capacity for the Van Son - Tan Tien area and the main drainage hub of the North Cau river basin.
The working delegation inspects the field of items belonging to the natural disaster prevention and control project.
Next, the working delegation inspected the discharge culvert through the dike, the discharge basin, the stilling basin, and the construction site of the station house belonging to the emergency construction project of Duc Mai pumping station, My Thai commune.
The project had a total investment of 500 billion VND from the provincial budget, built to support drainage and natural disaster prevention for Kep, Lang Giang, Tien Luc, and My Thai areas, with a basin area of about 8,200 hectares. The pumping station had a total design capacity of 45 m³/second, including a station house, a suction basin, a regulating lake, a discharge basin, a discharge culvert through the dike, a discharge canal, and a system of mechanical and electrical equipment for management and operation.
According to the investor's report, as of July 7, the discharge culvert through the dike had completed about 90% of the volume. The dike body had been backfilled to an elevation of +9.3 m, equivalent to the old dike surface elevation; the operating gate had been installed, basically meeting flood control requirements.
The contractor was organizing construction in 3 shifts, mobilizing maximum manpower, machinery, and equipment; at the same time, stockpiling about 1,000 m³ of reserve soil to be ready to handle arising situations. The discharge basin item had piled 72/124 piles, reaching about 58%; the stilling basin had completed piling all 44 piles and was constructing the bottom slab.
The manufacturing of 6 pumps reached about 40%, mechanical equipment reached 50%, and electrical equipment was being ordered. The investor set a goal to complete the discharge culvert through the dike before July 15, complete the stilling basin before August 5, and implement the remaining items immediately after having the site.
The contractor concentrates manpower on constructing reinforced concrete items of the project.
In 2026, the project was allocated 170 billion VND; by the time of inspection, more than 141.3 billion VND had been disbursed, reaching over 83% of the assigned capital plan.
However, the project progress was under great pressure from site clearance. The hub area had about 3.1 ha of land belonging to 105 households to be recovered; so far, payments had been made to 89 households, with an area of about 1.8 ha. The remaining site was still scattered, making synchronous construction organization impossible. In addition, the project also faced difficulties due to a shortage of backfill soil and increasing prices of materials, fuel, and labor.
Through inspection, Vice Chairman of the Provincial People's Committee Le Xuan Loi requested the investor and contractor to review the entire critical path schedule, clearly defining each work milestone and execution responsibility; focus highest on the discharge culvert through the dike, the stilling basin, and items directly related to flood control safety.
He emphasized that the dike cutting position under construction must be specially controlled. Units must maintain a regular inspection and monitoring regime, build project protection plans corresponding to each rain and flood situation; fully prepare forces, reserve soil, machinery, and means for timely handling in case of incidents.
The Vice Chairman of the Provincial People's Committee requested the local authorities and the land fund development unit to focus on verifying land origins, complete compensation plans, resolve dispute cases in accordance with regulations, and hand over the site early to implement the station house and the remaining items.
Regarding difficulties in materials, specialized agencies should urgently clear procedures related to backfill soil sources and update material prices close to market trends. Increasing shifts and construction fronts was necessary but must go hand in hand with controlling material quality, technical processes, and labor safety; not chase after volume at the expense of the durability and long-term operating capability of the project.
Overview of the construction area of the hub items of the project.
At the emergency construction project of Cam Bao pumping station at K20+300 of the left Cau dike, Xuan Cam commune, the working delegation inspected the discharge culvert through the dike, the drainage pumping station house area, the suction basin, the discharge basin, the river-side dike slope, and equipment preparation.
The project had a total investment of 450 billion VND from the provincial budget, aiming to ensure dike safety, serving water drainage for about 1,100 ha and irrigation for about 2,050 ha of agricultural land. The project consisted of a drainage pumping station with a capacity of 16.67 m³/second, an irrigation pumping station with a capacity of 4.17 m³/second; a station house, a suction basin, a discharge basin, a discharge culvert through the dike, a trash removal system, a substation, and irrigation and drainage canal routes.
The project also performed jet grouting to treat piping and boiling phenomena, waterproof the dike body and foundation; construct a pressure relief berm, reinforce the dike slope, widen the dike surface combined with traffic, and permanently block old culverts. This was an overall solution that both improved irrigation and drainage capacity and ensured long-term safety for the left Cau dike line.
By July 7, the overall progress of the project reached about 23%. The item of relocating the medium-voltage power line and jet grouting for dike body waterproofing had been completed. The discharge culvert through the dike had completed piling and the entire reinforced concrete body part; two culvert gates on the river side had been installed, and the backfill soil had reached the current dike surface elevation.
At the drainage pumping station house, the casting, piling, and foundation bottom concrete had been completed; the contractor was erecting reinforcement and formwork for walls up to the machine floor. The volume of casting dike slope lining slabs reached about 60%, the concrete frame beam of the river-side slope reached 62%, and the slab lining part reached about 36%.
Equipment contractors were simultaneously fabricating pumps, pipelines, and mechanical and electrical equipment. The site of the hub area, with an area of about 5.6 ha, basically met construction requirements. However, about 10 ha serving the construction of the irrigation pumping station and the drainage canal system still needed continued compensation and recovery.
In 2026, the project was allocated 340 billion VND; by the reporting time, nearly 91.9 billion VND had been disbursed. The investor set a goal to complete the discharge culvert items, the river-side dike slope, and the field-side pressure relief berm; continue constructing the drainage canal system, irrigation pumping station, and management house, and complete the entire project before June 30, 2027.
Vice Chairman of the Provincial People's Committee Le Xuan Loi requests the investor and contractor to review the construction plan and clearly define priority items.
Through practical inspection, Vice Chairman of the Provincial People's Committee Le Xuan Loi requested the investor to organize construction simultaneously on multiple fronts but must clearly define the order of priority, first of all, items directly related to the safety of the left Cau dike and flood control capability. Foundation work, waterproofing jet grouting, construction of the culvert through the dike, dike body backfilling, and equipment installation must be tightly controlled from the beginning.
The Vice Chairman of the Provincial People's Committee requested investors, contractors, and project management units to enhance their responsibility; maintain standby forces, fully prepare materials, machinery, and means according to the "four on-the-spot" principle; and regularly monitor weather developments, river water levels, and the project's current status.
Departments, sectors, and localities should strengthen coordination, focusing on resolving obstacles in site clearance, material sources, and investment procedures. Issues beyond their authority must be aggregated and reported immediately to the Provincial People's Committee, not allowing them to drag on and affect urgent items.
Completing on schedule, ensuring the quality and safety of Van Son, Duc Mai, and Cam Bao works not only served natural disaster prevention and control requirements during the 2026 rainy and flood season but also contributed to improving drainage capacity, protecting production, residential areas, and socio-economic activities in the province./.
