The Me Tri Lake project (Dong Bong 2) on To Huu street, Dai Mo ward, has a total investment of approximately 370 billion VND. The 12-hectare facility features an embankment over 1.9 km long, a regulating culvert connecting to the Dong Bong canal, and control gates to manage the lake's water level.

The main lake has been filled with water, while the auxiliary lake remains in the completion phase. After finishing the sub-lake components and shoreline embankments, the contractor is focusing on constructing landscaping, walkways, and the railing system before the project becomes operational.

In An Khanh commune, the Yen Nghia one and Yen Nghia two regulating lake projects are taking shape. Yen Nghia two Lake, spanning approximately 5 hectares with a total investment of 250 billion VND, has been largely completed and began retaining water after rainfall in May.

Paving of walkways and installation of the lighting system around Yen Nghia two Lake have been completed. Since early June, machinery has been withdrawn from the site to focus on constructing Yen Nghia one Lake. Two dam gates are ready for operation to regulate water for flood control.

Yen Nghia one regulating lake spans 20 hectares with a total investment of 858 billion VND. The project aims to complete Hanoi's regulating lake system according to the drainage master plan, while enhancing the operational efficiency of the Yen Nghia pumping station.

According to the design, the lake will have a water depth of 4 meters, a surrounding embankment 2.5 km long, and connect to the La Khe canal via a 3x3 meter regulating culvert and water level control gates. Currently, the contractor continues to excavate and fill the lake bed, while installing the electrical system in preparation for lighting and landscaping components.

The project to renovate the lower Kim Nguu river, connecting the To Lich river with the Yen So pumping station, has a total investment of approximately 700 billion VND. It aims to increase water storage, conveyance, and drainage capacity for southern Hanoi. The project includes pre-stressed concrete embankments along both river banks spanning 5.3 km, dredging the riverbed to a depth of 3.6 meters, and constructing a culvert connecting to Linh Dam Lake. Currently, the contractor is simultaneously dredging the riverbed and driving piles in the Nguyen Bo street area, Thanh Tri commune.

In Dong Ngac ward, the Thuy Phuong two regulating lake project has largely taken shape and is entering the final phase of completing components such as lake embankments, the drainage system, and surrounding landscape improvements.

The project aims to progressively complete Hanoi's regulating lake system according to the drainage master plan, contributing to flow regulation, increased water storage capacity, improved landscaping, and reduced flooding in the area. The lake has a total capacity of approximately 500,000 cubic meters, with a regulating capacity of about 400,000 cubic meters. Near Pho Vien street, the contractor is constructing a collection culvert system to channel water towards Thuy Phuong two regulating lake. This is a critical component for connecting the lake to the area's drainage system upon completion. According to the design, water from the lake will be directed through an underground culvert system along Pho Vien street and the Tay Thang Long axis before discharging into the Nhue river. Currently, the collection culvert system and the pumping station along the Nhue river have been largely completed, ready for synchronization with the entire project.

Phu Do regulating lake in Tu Liem ward, spanning approximately 36 hectares with a total investment of nearly 800 billion VND, has largely taken shape. Major components such as lakebed excavation, surrounding pre-stressed concrete embankments, and the culvert system connecting to the local drainage network have been completed, preparing for the operational phase.

Once operational, the regulating lake will connect to the Mai Dich - Phu Do and My Dinh - Tan My canals via an underground culvert system, enhancing water storage, rainwater regulation, and flood reduction for the area.

Water from the lake will naturally flow into the Nhue river when water levels permit. Should river water levels rise, drainage will be managed through the Dong Bong one-two pumping station, ensuring the entire system's operational capacity.

The Thuy Phuong headworks pumping station has completed the installation of four pump units, along with mechanical, electrical systems, and a transformer station, ready to enter the trial run phase. When operational, the facility will draw water from the Hong river through a canal system to replenish the To Lich river at a flow rate of approximately 5 cubic meters per second. Along the canal route via alley 104 Thuy Phuong, the contractor is simultaneously deploying multiple construction teams to accelerate progress. Concurrently with completing major components, site restoration along the route is also being carried out to quickly restore the area's infrastructure and landscape.

The box culvert system from Hoang Minh Thao street is largely complete, with nearly 1.9 km of culverts installed, creating a water conduit connecting to the replenishment system for the To Lich river.

Meanwhile, the culvert system along Vo Chi Cong street has completed all components, including box culverts, underground jacking, and discharge gates. The contractor has also restored the road surface and completed the lighting system, greenery, and related technical infrastructure.
