This is a funnel that captures and directs water towards the power plant.
There are two types of water intakes:
Front intakes
Intakes from below.
The water intake can be located in different places:
Upstream of the dam,
Alongside the watercourse,
In the bed of the watercourse, etc.
It all depends on the nature of the watercourse or body of water, for example:
In a river, it is rare for the water intake to be located at the bottom because of the large amount of debris carried by the current (water intake from below or Tyrolean intake),
In a lake, a water intake through an underground gallery can be an excellent option
Different functions
The water intake is a receptacle that must be protected by screens to facilitate waste removal and prevent fish from passing through.
The spacing between the bars of the water intake screens is therefore important.
The technical choices made when designing the water intake structure depend on the water quality. The water intake must be sized according to the water velocity and its cleanliness.
It also has a desilting function and includes a settling basin and a gate that allows the deposits and the bottom of the water intake to be emptied.
HYDROSTADIUM has all the expertise and know-how required to design and develop water intakes and thereby improve the power plant’s efficiency.
Thanks to its engineers and highly advanced calculation techniques, every effort is made to meet clients’ expectations.
