One of them is the investment project to build an emergency project for Phu Do regulating lake. This is also a project belonging to 10 emergency flood control projects with a total investment of nearly 5,500 billion VND, showing the urgency and necessity in solving current flooding.
The flooding situation in major cities of Vietnam, especially Hanoi and Ho Chi Minh City, has become a serious problem, significantly affecting people's lives, traffic and the environment. Although functional agencies have implemented many measures to solve this situation, the level of effectiveness has not yet met requirements. Therefore, more drastic solutions are needed, especially in the context of climate change and increasingly severe heavy rain.
These two localities have implemented a number of flood control projects such as building regulating lakes, upgrading pumping stations and renovating sewer systems. However, these solutions still face many difficulties in thoroughly resolving flooding. One of the biggest problems is the lack of synchronization in planning and deploying infrastructure projects, especially drainage systems.
Hanoi has just planned to add 2 underground tanks at flood hotspots. However, the scale of these projects is still too small compared to actual needs.
The solution of underground water tanks regulating water with large-capacity underground tanks is one of the effective solutions to solve flooding. Underground tanks not only help store rainwater temporarily but also take advantage of underground space for transportation and commerce, helping to save urban land area. However, Hanoi needs hundreds of such underground tanks and requires large capital mobilization.
In addition, renovating and upgrading the existing drainage system needs to accelerate progress and ensure the quality of the project to avoid prolonged flooding after rain.
In particular, urban areas in Vietnam need to invest in technology and digital transformation: New technologies, such as rainwater monitoring and regulation systems through digital platforms, need to be widely applied. This technology not only helps enhance the ability to monitor and coordinate rainwater but also helps accurately forecast areas at risk of flooding, thereby having timely response plans.
Flooding, traffic congestion and air pollution are the 3 biggest problems of Hanoi. The fact that the Hanoi People's Committee activated the "Urgent Construction Order" mechanism for ongoing flood control projects and the ambition to build underground tanks is assessed by experts and people as a courageous and very timely policy response.
