In early November, two fish-friendly Archimedes’ enclosed screw pumps from FishFlow Innovations were loaded onto a ship to New Zealand. The screws have a diameter of ø 3 meters and a total length of almost 18 meters. The screw pumps will replace a pumping station that is located between Auckland and Hamilton. If the journey goes according to schedule, the screw pumps will arrive in Auckland by Christmas.
The new fish-friendly pump from FishFlow Innovations is helping native fish to safely passage downstream on Ngāti Te Ata Waiohua land in Waikato.
Tuna live in streams and drains for many decades but breed once in their lifetime out at sea.
Water pumped through the new Mangawhero Pump Station enters a lake on the iwi-owned, 10-hectare property before joining the Waikato River. It’s part of Waikato Regional Council’s upgrade of five pumps in Waikato catchments.
Some 160 tuna were tagged during their migration season, which occurred during the recent downpour and flooding. But Roimata Minhinnick (Ngāti Te Ata) says despite the earlier-than-usual migration, the results meant that the pump is correctly doing what it’s meant to do: enable fish safe passage through the pump, as the old, current pumps are lethal to 100% of the Tuna.
Gerard Manshanden knows a lot about fish behaviour, applying his knowledge to provide safe fish passage at pump stations, worldwide – and soon, in Southland.
Two of FishFlow Innovations pumps are being installed in the new Stead Street pump station, replacing the old pumps, which are more than 70 years old and, unlike the new pumps, do not provide safe passage for our native fish.

New Zealand’s first ever Fish Flow Innovations screw pump will be tested during the next fish migration to see how New Zealand’s native fish species successfully migrate through our system.

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?
