Water usage with minimum impact on the environment
Your SETUR turbine is the most environmentally safe micro-hydro system in the world, the winner of
ECOLOGICAL OSCAR 2014. However, as any other hydropower system it may potentially affect:
➢
Plants and fish in the water
➢
Plants and animals outside the water
➢
River banks and surrounding land
You must check with your local authorities to see if you need to obtain consent either to build any
structures or to take/return water from/into a waterway. The impact of your system on stream/river
ecology will usually be considered during this process.
Unlike most other micro-hydro systems SETUR does not divert any water flow from the water source.
SETUR turbine is designed to work directly within the available water source e.g. river, stream, canal. A
good intake screen will minimize the chance of fish, leaves, debris etc entering the turbine.
Your local wildlife protection authorities might have specific requirements as to the size of the mesh
screen. Please refer to any rules and regulations your locality might have in place.
We recommend a two stage protection of the turbine.
➢
Outer 50 mm mesh screen to prevent larger debris from damaging the system
➢
Inner 25 mm mesh screen to prevent from leaves and smaller pieces
It is highly advisable to make the screen protuberant towards the water flow in order to deflect the debris,
plants, fish etc.
Taking less than 50% of the minimum seasonal flow rate in your water source means there is no
impediment to fish moving up or down stream and hence gives aquatic life a better chance to survive.
In case you choose to route the water to your turbine via a pipe or an aqueduct, you should take care to
ensure that the exhaust water from the turbine returns to the water source e.g. river, stream, canal.
