Hanoi Turns into a “Sea of Water” Overnight: THE MOBILE FLOATING DAM SOLUTION FROM SWITZERLAND

Hanoi Turns into a “Sea of Water” Overnight:
THE MOBILE FLOATING DAM SOLUTION FROM SWITZERLAND

The extreme rainfall brought by Storm No. 5 caused rare and severe flooding in Hanoi. Overnight, major streets such as Pham Hung, To Huu, and Duong Dinh Nghe turned into unexpected “rivers.” Rainfall in some areas exceeded 460 mm, highlighting the growing severity of extreme weather events.

This situation once again raises the urgent need for proactive and flexible flood prevention solutions in large cities like Hanoi. While traditional measures such as upgrading drainage systems or building retention lakes require huge budgets and long timelines, mobile floating dam technology has already proven effective in many countries.

One of the most recognized solutions is the Beaver® floating dam system from Switzerland – a flood control technology applied worldwide for over 23 years. Beaver® stands out for its quick deployment, flexibility across all terrains, and multiple reuses, making it a cost-saving long-term option. It has been trusted by rescue teams, militaries, and international humanitarian organizations in thousands of emergency situations.

The principle is simple but effective: the tubes are inflated with air, then filled with water from rivers, lakes, or hydrants. Once in place, the connected modules form a strong “soft levee” to block floodwater. Compared to traditional sandbags, Beaver® is lighter, easier to transport, can be installed many times faster, and after use can be dismantled, folded, and stored compactly. Its special material ensures durability, high resistance, and safety for both operators and the environment.

This solution is not only suitable for protecting residential areas and urban infrastructure, but also highly effective in safeguarding factories, warehouses, and industrial facilities – places that often suffer heavy losses during flooding.

Amid worsening climate change, Beaver® is considered a “soft shield” for cities: lightweight, mobile, cost-effective, and reliable. It could be a practical path for Hanoi and other major cities to minimize damage and strengthen resilience against future extreme rainfall.

Key Technical Features of Beaver®

• Height: 0.5 m to 1.2 m, can be stacked 2–3 layers to block up to 2 m of water.
• Module length: 5–10 m, easily connected into hundreds of meters.
• Deployment time: only 15–30 minutes for 100 m of dam, with minimal manpower.
• Material: premium technical fabric with synthetic UV-resistant coating, durable and long-lasting.
• Pressure resistance: stable even under strong currents and high water levels.
• Reusability: lifespan up to 20 years, foldable and easy to store.

Compared with traditional methods such as sandbags or temporary levees, Beaver® excels in mobility and economic efficiency. Without heavy machinery, just a few people can quickly protect critical areas such as pumping stations, factories, riverside neighborhoods, or flooded streets.

In the face of increasingly frequent extreme rainfall in Hanoi, Beaver® is not just an immediate “firefighting” solution, but also a strategic tool for proactive flood response, infrastructure protection, and public safety.
