Managing quickly rising water levels

In early January 2025, the town of Redon, located in the Brittany region of western France, experienced its worst flooding in 40 years. Weeks of continuous rainfall caused the Vilaine River to overflow, a situation worsened by the passage of Storm Éowyn and Storm Herminia, which brought heavy wind and additional rainfall to already saturated ground. More than 15,000 people were affected, with homes, businesses, and infrastructure disrupted across the region.

High volume pumping power with new HydroSub 250 units
To respond to the rapidly rising water levels, authorities deployed two Hytrans mobile pump systems. The newly delivered HydroSub 250 with FloodModule (containing FloodPumps and FloodHoses), operated by the Directorate-General for Civil Protection and Crisis Management, was put into action for the first time.

It was supported by a HydroSub 150 unit with FloodModule (containing FloodPumps and FloodHoses) from the Seine-Maritime fire and rescue department (SDIS 76). Together, these systems provided continuous high-volume pumping to redirect floodwater away from critical urban areas

Need for flexibel, mobile systems
The response showcased how advanced mobile water transport can be rapidly deployed and integrated into regional civil protection strategies. Operating in challenging, waterlogged terrain, the systems helped lower water levels and prevent further damage to residential zones and public infrastructure.  

This case underlines the growing need for flexible, high-capacity flood response solutions as Europe experiences more frequent and severe weather events.
