The Fish-Friendly Pump
Challenge
In Belgium, water pumping stations are essential for flood control and water management. However, these installations pose a severe threat to aquatic life—especially eels, one of the most endangered fish species in Europe. Since the 1960s, eel populations have declined by 90%, largely due to migration barriers like traditional pumps.
Eels migrate from inland waters to the Sargasso Sea to reproduce, but many never make it. Studies show that in some pumps, up to 97% of eels are killed due to the sharp blades and high-speed flow of traditional pumping systems. To counter this alarming decline, the Belgian government sought innovative solutions to create a fish-friendly alternative for water management infrastructure.
Our Solution
Van Hooste, a leader in mechanized water solutions, took on the challenge. With over six decades of expertise, the company developed Belgium’s first fully fish-friendly water pumping system, ensuring safe fish migration while maintaining water flow efficiency.
Results & Impact
To validate the design, the pump underwent extensive testing in partnership with the Institute for Nature and Forest Research (INBO). The results exceeded expectations:
Almost 100% survival rate for eels and other fish species
Successful adaptation to large-scale water management systems
Compliance with EU Nature Restoration Laws and upcoming regulations
