Vortex drop structures are popular in sewer and hydropower systems where they are used to convey water from a higher to a lower elevation and dissipate its energy safely.

The Hydro Vortex DropTM Shaft, is a self activating energy dissipation system with no moving parts, designed to safely drop water or sewage from virtually any height in order to protect the …

Mar 1, 2025 · Vortex drop shafts are special structures through which a nearly horizontal free-surface flow is forced to rotate and turn into a swirling flow across the vertical shaft.

The Hydro Vortex Drop™ Shaft provides a smooth transition from the vortex mode to the pipe full mode, avoiding glugging noises and destructive vibrations caused by the system taking in …

The Vortex Drop Shaft is the vertical pipe in which the sewage spirals down. The shaft may come in more than one piece and will have a slip coupling or flange as a means of assembling the …
