On June 10, 2026, a sudden water pipe burst in Sundsvall’s town center, triggering an intense flash flood. Fast-flowing surface water advanced towards nearby businesses and properties. Immediate emergency intervention was required to prevent asset damage and business closure before the water utility company could isolate the leak.

The Solution: Rapid NOAQ BOXWALL Deployment
First responders from the Medelpad Rescue Service Association arrived swiftly at the scene equipped with NOAQ Boxwall. The team rapidly deployed the 50 cm high lightweight mobile flood barrier system to hold back and safely divert the floodwater away from a nearby restaurant and other local businesses.
How NOAQ Boxwall Works
NOAQ Boxwall is a modular, freestanding, self-anchoring mobile flood barrier system designed for rapid deployment on relatively even surfaces like asphalt and concrete. It utilizes several key design features to deliver fast, effective, and reliable flood protection:
- The Bookend Principle: Invented by NOAQ in 1995, this technology uses the weight of the incoming floodwater to anchor the barrier. No fixings, weights, or moorings required. As water rises, downward pressure forces the barrier firmly against the ground, ensuring it remains stable even if overtopped.
- Tool-Free Assembly: A simple integrated coupling and locking mechanism allows for quick and easy connection without the need for any tools or advanced technical training. A two-person team can deploy hundreds of meters of flood protection in minutes.
- Built-In Flexibility: The locking mechanism has a degree of built-in flexibility that allows the barrier to form gradual curves and handle slight terrain gradients. The system can still be adjusted and repositioned even after the components are connected.
- Urban Adaptability: The modular system easily navigates the urban environment and avoids obstacles along the flood defense line. The mobile design makes the flood barrier equally effective at holding back rising water and diverting fast-flowing runoff.

The Outcome: Commercial Property and Business Protection
While the initial burst water pipe flooded the restaurant's outdoor seating area, NOAQ Boxwall successfully created a temporary flood defense line, preventing water from entering the building and causing damage.
The entire outdoor seating area filled with water, but thanks to NOAQ Boxwall, we were able to prevent water from entering the restaurant. The barrier was quick and easy to assemble.

Key Benefits NOAQ Boxwall Delivered
- For the Emergency Services: Provided rapid deployment that allowed a small team to secure the area in under 20 minutes, drastically cutting response times and labour needs.
- For the Water Utility Company: Minimized infrastructure and private asset damage and liability costs, and bought critical time for repair crews to isolate the burst pipe.
- For the Restaurant Owner: Prevented any indoor flooding and asset damage, saving the business from any cleanup costs, insurance claims, and operational downtime.
The Cost of Inaction
For municipalities, water utility providers, and business owners a lack of protection against flash floods can lead to measurable financial impacts:
- Municipalities: Unaddressed flood threats compromise public safety and elevate the risk of infrastructure damage and commercial downtime, ultimately depressing local tax revenue and GDP.
- Water Utility Providers: Unmitigated flooding from utility failures elevates the risk of damage to public infrastructure and private property, leading to higher liability costs.
- Business Owners: Unprotected sites frequently face high out-of-pocket repair bills, increased insurance premiums, lost revenue during disruption, and the long-term risk of permanent closure.
