Removable Fish Weir

Removable fish weir for steel culverts, adapted to the forest environment, that allows the crossing of a watercourse without disturbing the fauna and flora of an ecosystem

Removable control structure in galvanized steel, comprising a half-moon-shaped base and a slowing plate, with an opening for passage of the fish.
Because it’s removable, our weir preserves the nesting of the pipes during transportation and optimizes the loading space for added savings.
Easy to install on site,this structure fits into a steel culvert installed in a watercourse to reduce water flow and reproduce the natural aspect of a stream.
The weir’s wide base allows adequate interlocking with the steel pipe, ensuring the stability of the installation.
Made of hot galvanized steel, the weir is resistant to corrosion.
The sealant joint applied during installation ensures that the system is watertight and perfectly retained.
Riveted or bolted to the steel pipe, the weir is strong and vibration resistant.
With added buttresses, the weir provides optimal resistance to the pressures exerted by the flow of water, and to impacts caused by natural debris.
Available for steel pipe diameters from 1200 mm to 3600 mm (48 in to 144 in).

Manufactured in accordance with the requirements of section 106 and Annex 10 of the RADF

Advantages and Benefits

Soleno’s patent-pending removable fish weir meets the objectives of the new Regulations respecting the Sustainable Development of Forests in the state domain (RRSDF), by allowing for the free flow of water and the free movement of aquatic wildlife.
By reducing the water flow, the Soleno fish weir facilitates the passage and the countercurrent movement by the fish, while serving as a refuge for the fauna and the fry.
The flow speed reduction in the culvert reduces the erosion at the outlet, which is beneficial to the conservation and stability of the slopes.
