The Hydro Vortex Drop™ Shaft is designed to operate safely in both the air entrained 'vortex' and 'pipe full' modes and ensures a smooth transition between the different modes of operation. At low flows the drop pipes operate in the vortex mode, whilst at design flows they operate in pipe full mode.
The Hydro Vortex Energy Dissipation Unit (EDU) is a simple, self-activating energy dissipation device. It is small in comparison to conventional energy dissipation structures.
The Hydro Vortex Drop™ Shaft operates under pipe full conditions at design flows.
There is no requirement to keep an air core within the drop pipes as in conventional designs.
Pipe sizes are therefore significantly reduced from the conventional vortex drop equivalent.
Typically flows of 0 - 2000 l/s can be transferred safely through drop heights of up to 30 m. The use of multiple pipes can accommodate higher flow rates.
