Bertrand Piccard has published a selection of 1000 solutions through the Solar Impulse Foundation that are intended to address environmental challenges while enabling economic growth.

The FishFlow Innovations Archimedes Screw Turbine has been awarded with the “Solar Impulse Efficient Solution Label”.

The Solar Impulse Efficient Solution Label aims to shed light on existing or new solutions that are both clean and profitable and have a positive impact on the quality of life. The decision to award this label is only made after a thorough assessment based on a verified methodology and on the basis of various criteria, carried out by external independent experts..

In the Wieringermeer, a unique area is being developed to increase the spawning and habitat for fresh-salt migratory fish and to improve the water quality.

FishFlow Innovations has supplied two Syphon fish ladders for this project which are currently functioning to full satisfaction, below you can see an animation which explains the operation of our type of Syphon fish ladders .

Are you dealing with a situation in which a fish-friendly siphon fish ladder would offer a solution?

Located next to the hamlet of Scheve Klap, FishFlow Innovations has installed a fish-friendly pumping station which adjusts to fluctuating water levels on the Weerdijk for the Hunze & Aa’s water board.

The Hunze & Aa’s water board has the vision to map out the additional fish mortality in fish migration bottlenecks, so that these problems can be minimized during new construction and renovation of pumping stations (See also the news item: Hunze & Aa’s wants more fish-friendly pumping stations).

A fish safety test has now been carried out at the Weerdijk pumping station to determine the mortality percentage of fish after passing a FishFlow Innovations fish-friendly, water level folowing, pumping station and have further investigated the following:

• The mortality that occurs immediately after passing the pumping station, and

• The delayed death, 24 hours and 48 hours after passage.

It has been found for all test groups that the mortality percentage is 0% and that forms of damage occur only very little or even not (with large eels).

The conclusion is therefore that the fish-friendly screw pump from FishFlow Innovations as used in the Weerdijk pumping station is very fish-friendly and makes a good contribution to solving fish migration bottlenecks and greatly reducing fish damage and fish mortality from pumping stations.
