Need to soon invest in upgrading the dike system in Dong Trieu ward

Dong Trieu Ward is one of the localities with a large dike system in the province, including 7 dike lines with a total length of nearly 20km. Recently, due to the impact of storms and rains and long-term use, some dikes have degraded, posing a potential risk of insecurity and flooding when there is prolonged heavy rain. Regarding this content, reporters of the Provincial Newspaper, Radio and Television interviewed Mr. Le Van Hung, Vice Chairman of the People's Committee of Dong Trieu Ward.

Mr. Le Van Hung, Vice Chairman of Dong Trieu Ward People's Committee.

- Could you tell us about the current status of the dike system in Dong Trieu ward?

+ In recent years, with the support capital from the Central Government combined with local resources, Dong Trieu ward has invested in upgrading and renovating a number of key dikes such as Hong Phong - Hung Dao dike. However, in reality, there are still a number of dikes under the Government 's sea and river dike program that have not been upgraded due to difficulties in investment capital. In particular, after the impact of storm No. 3 in 2024, combined with the impact of tides, floods and regulated discharge from hydroelectric reservoirs, many dikes in the ward have a high risk of insecurity.

Some dike sections do not meet technical standards, the dike crest elevation is low, the foundation is weak, the soil composition has a high sand ratio, the dike slope is steep, causing the risk of seepage, overflow, subsidence, and landslide when the river water rises. Typically, the dike routes: Tan Viet - Duc Chinh, An Bien, Binh Duong - Dong Mai... currently have many locations that have not been upgraded or repaired, low elevation, storm resistance capacity is only from level 6 to level 9, so when encountering high tides or big storms, the risk of overflow, seepage, and loss of construction safety is very high.

Notably, some sections do not ensure the width according to design standards, averaging only 2-2.5m, which does not meet waterproofing requirements and causes difficulties for disaster prevention and rescue work. Some sections of the Binh Duong - Dong Mai dike route currently have a dike surface width of only 2-3m, the lowest section is only 1.5m, weak foundation, and steep roof. These are locations that need to be invested in and reinforced early to ensure safety during the rainy and stormy season.

- How does the state of some dikes that are degraded and do not meet technical standards affect people's lives and disaster prevention work in Dong Trieu ward, sir?

+ Dong Trieu Ward was established on the basis of merging 5 wards and communes: Duc Chinh, Hong Phong, Hung Dao, Thuy An, Nguyen Hue. With a natural area of ​​40.41km² and a population of over 43,700 people, Dong Trieu is one of the large-scale wards, holding a strategic trading center position in the West of the province. In the period of 2025-2030, Dong Trieu Ward is oriented to strongly develop trade - services - industry in a modern and sustainable direction; to be a typical locality in developing high-tech agriculture and green agriculture. Therefore, the dyke system in the area plays a particularly important role in preventing natural disasters, storms and floods, responding to climate change and protecting people's lives and property. However, currently, some dykes have degraded, no longer meeting technical standards, posing many risks during the rainy and stormy season.

In fact, the fact that some dikes are degraded and lower than the design elevation has affected the safety of residents, production infrastructure and the lives of people living along the river, posing a high risk of insecurity during the rainy and stormy season. When there is prolonged heavy rain, floods combined with high tides, rising river water increases seepage pressure, overflows and landslides of dike slopes, posing a risk of dike failures and widespread flooding, especially in agricultural and aquaculture areas. In early October 2025, due to the impact of high tides combined with upstream floods and regulated discharge from hydroelectric reservoirs in the Northwest region, the rising water level of Kinh Thay River caused many residential areas outside the Hong Phong dike (Dong Trieu ward) to be flooded, directly affecting people's lives and production activities.

The Nguyen River dike (Dong Trieu ward) is degrading and needs investment and repair.

In addition, the narrow dike surface and weak foundation also make it difficult to patrol, inspect, respond and deploy forces and vehicles in emergency situations, directly affecting the effectiveness of local disaster prevention and search and rescue work. In the long term, the unsafe state of the dike also hinders socio-economic development, because riverside production areas, aquaculture areas and residential areas all depend heavily on the protection capacity of the dike system.

- What recommendations has the Ward People's Committee made regarding investment and upgrading of the dike system in the area?

+ Faced with increasing pressure from natural disasters, storms, floods and high tides, investing in and comprehensively upgrading the dike system is a strategic, urgent and unprocrastinable task.

The ward has prepared a report and proposed to the province to include key dike routes in the Project to improve the safety of the dike system in Quang Ninh province, adapting to climate change in the period 2025-2030, with a vision to 2050, including: Binh Duong - Dong Mai, Van Dong, An Bien, Tan Viet - Duc Chinh, Song Nguyen... with a total length of more than 18km, with a total investment of over 400 billion VND.

For households living in Ben Trieu and Dong Tan areas, located outside the Hong Phong - Hung Dao dike, the locality also recommended that the province consider building an additional dike perimeter road outside the old dike foot, to increase flood prevention capacity and ensure safety for residential areas and production areas along the river.

When the above items are deployed, the capacity to prevent natural disasters, prevent tides and protect residents and production in Dong Trieu ward will be significantly improved, contributing to ensuring safety for downstream areas and promoting sustainable socio-economic development.

Thank you!
