Speed to bring underground works and regulating lakes to completion
According to records, in front of Hang Da market area (Hoan Kiem ward, Hanoi), the construction unit has restored the road surface after more than 3 months of erecting barriers (area of about 800m2) to serve the urgent construction of an underground regulating tank in the Hang Da market area.
The site handed over on schedule not only makes travel more convenient, but also puts one of the city's emergency flood prevention projects in a state of operational readiness before the rainy season.
The Hang Da underground water tank project is on the list of flood prevention projects implemented under an emergency order of the Hanoi City People's Committee with a total investment of more than 30 billion VND. The project has a storage capacity of 2,500m3 of water, a tank bed area of 903m3 and is located at a depth of about 6.5m above the road surface.
After completion and commissioning, the project will perform the task of collecting and storing rainwater, contributing to reducing localized flooding at "black spots" of prolonged flooding in the area in front of Hang Da market and the intersection of Duong Thanh - Bat Dan - Phung Hung - Nha Hoa streets.
In addition to the above project, a series of other flood control projects are also being implemented at the same time. On Vo Chi Cong and Hoang Minh Thao streets, in the past time, the contractor has carried out barricades, excavated deep soil in the roadway, and pressed piles to install underground culverts for drainage.
Up to now, in some sections on Vo Chi Cong street, the construction unit is restoring the road surface after completing the installation of the underground drainage system.
Hanoi also simultaneously implemented many emergency regulating lake projects with a total investment of up to trillions of VND, including: Phu Do Lake, Me Tri, Yen Nghia 1, Yen Nghia 2, Thuy Phuong 2, Chem, Lien Mac...
Prominent is Phu Do regulating lake (Tu Liem ward) with a scale of up to 36ha, total investment of 1,166 billion VND. The project's goal is to solve the prolonged flooding situation in the west of the city, which is an area under strong urbanization pressure.
For this project, Hanoi requests the investor and contractor to mobilize resources, accelerate construction, ensure quality and safety, and strive to complete the entire project by the end of June 2026.
Thai Nguyen: Building dykes, bridges and reservoirs to cut floods
After many historic floods, Thai Nguyen is implementing a series of large-scale flood control projects in the central area. From renovating drainage systems to building bridges, dikes and flood-cutting lakes, the locality expects to gradually solve the problem of "flooding whenever it rains heavily".
In mid-May 2026, at the construction site of the new Gia Bay bridge across the Cau River, dozens of workers and machinery were operating continuously. The sound of drilling piles and excavators echoed throughout the river section. Both ends of the old bridge were carefully fenced to ensure safety for vehicles.
In the past 2 years, Thai Nguyen has continuously experienced heavy rains causing widespread flooding. In particular, the historic flood in early October 2025 left heavy consequences when nearly 70,000 houses were flooded, many residential areas were submerged deep in water, with estimated damage of more than 12,200 billion VND.
Not only the riverside area, many central streets also fall into the scene of "towns becoming rivers" every time prolonged heavy rain appears. People on Minh Cau, Hoang Van Thu, Hoang Gia streets or Thai Nguyen University area are too familiar with the scene of water flooding into houses, traffic paralysis, and business disruption.
Up to now, some renovation items in the central area of Thai Nguyen have shown initial effectiveness. At the Minh Cau - Hoang Van Thu intersection, the flooding situation has decreased significantly compared to before. In the early rains of this year, the water receded faster, and traffic was basically not interrupted.
According to records, many streets that were once "black spots" of flooding no longer have the scene of rising water lasting for many hours as before.
However, local leaders believe that the existing drainage infrastructure system on central streets still has many shortcomings due to being invested from many different stages, not keeping up with the rapid urbanization rate.
The concretization of urban surfaces, population growth and the impact of climate change are increasing the risk of flooding. Therefore, Thai Nguyen is forced to deploy large-scale projects to solve the fundamental problem.
Prominent among the projects being implemented is the new construction of Gia Bay bridge with a total investment of more than 617 billion VND, started in early February 2026.
The project belongs to group B, level I traffic, designed as a cable-stayed bridge with a length of more than 180m and a width of 23.5m. The project includes the synchronous construction of a system of approach roads at both ends of the bridge to increase traffic connectivity and support flood drainage in the Cau River area.
The new Gia Bay bridge is expected to replace the old degraded bridge, contributing to reducing the risk of congestion and ensuring safety for people during the rainy and flood season.
Not only stopping at traffic projects, Thai Nguyen also implements the Huu Cau dyke project section from Cao Ngan to Thac Huong dam with a length of about 15.9km.
The project has a total estimated investment of up to 8,512 billion VND, considered one of the largest-scale flood prevention and control projects in the province to date. The expected construction time is in the period 2026 - 2027.
This is phase 1 of the flood control system in the central area of Thai Nguyen province. According to the province's orientation, phase 2 will continue to deploy the construction of northern flood control reservoirs and Ta Cau dyke to form a synchronous flood prevention and control network for the entire central urban area.
Quang Ninh: Maintaining duty during heavy rain
At the end of 2025, Quang Ninh will deploy more than 500 urban and residential area embellishment projects with a total resource of about 2,300 billion VND. Among them, many flood treatment projects and works are being implemented in areas such as Cam Pha, Mong Cai, Quang Ha, Dam Ha, Tien Yen, Dong Trieu, Hong Gai, Ha Long, Uong Bi... These are areas that often experience localized flooding when it rains heavily.
However, to date, most of the projects are still in the process of implementation, not put into use and actual operation to be able to fully assess the effectiveness of flood control treatment.
While waiting for fundamental solutions to be completed, local authorities are maintaining on-duty plans when there is heavy rain; arranging forces to monitor and handle flooded points, ready to support people when situations arise.
Mr. Dao Tat Thang - Chairman of Hong Gai Ward People's Committee - said that to reduce flooding in the Yet Kieu Lake area, the ward has invested in a system of 3 forced pumps, each with a capacity of about 2,500m3/hour, replacing 2 old pumps with a capacity of about 2,000m3/hour.
The locality also changed the operating plan of the pumping station. Before heavy rain, the pumping system will operate to lower the water level in the regulating lake, creating a water storage capacity. When it rains heavily, the pumping station will continue to operate to increase drainage capacity.
The Ward People's Committee is implementing the Project to renovate, upgrade, and renovate in combination with flood treatment on streets in Yet Kieu 2, Yet Kieu 3, Yet Kieu 4 and Tran Hung Dao 4 areas with a total investment of nearly 57 billion VND. Currently, the project is under construction, in which some sewer lines are expected to be completed in June 2026.
