Micro hydro is a type of hydroelectric power that typically produces ... An intake structure such as a catch box is required to screen out floating debris and fish ...
In 2010, TrustPower (now Manawa Energy) installed a river intake, fish screening, and pumping facilities to deliver the water from the Rakaia River to the RDR using some of the existing Highbank Power Station facilities. The Highbank Power Station site has been equipped with an array of six 1.5 MW pumps that allow it to take water from the ...
Low-head hydro power refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. [1] Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge.

Larger projects have more environmental concerns. For fish-bearing rivers, a ladder may be required, and dissolved gases downstream may affect fish. In British Columbia, the mountainous terrain and wealth of big rivers have made it a global testing ground for 10–50 MW run-of-river technology. As of March 2010, there were 628 applications ...

We’ve seen in previous studies that regular fish intake is associated with a reduced risk of gastrointestinal cancers, as well as being a potential benefit for cancer survivors who have diets ...
A schematic presentation of a gravitation water vortex power plant, showing the turbine in yellow. The gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in).
