Screw Pumps at Churchill East Road installed

Today, 2 fish friendly Archimedes’ screw pumps of 3.0 m diameter have been installed in Hampton Downs, New Zealand. The pumps have been designed to displace a total of 4.5 m³ of water per second to the Waikato river.

ø 3m screw pumps en route to Auckland

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.

Fish-friendly pump keeping eel (tuna) numbers up and free of harm.

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.

Interview Gerard Manshanden: From fisher to fish passage innovator

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.
