HOW TO DESIGN AN EFFECTIVE VORTEX DROP SHAFT
Drop structures are applied in sewer and drainage systems to manage risks associated with erosion, hydraulic shocks,
cavitation and vibration, which have the potential to damage the drainage infrastructure. These hazards arise due to
the increase in kinetic energy when flow is transported from a high to low level. Effective drop structures safely
dissipate excess flow energy and eliminate the potential for damage to the surrounding structures.
The Hydro-Brake Drop® is a proprietary drop structure technology developed and provided by Hydro International Ltd with over 80 installations worldwide. As Singapore continues development of Phase 2 of the Deep Tunnel Sewerage System, which incorporates a conveyance system made up of 60km of link sewers and 40km of deep tunnels, an understanding of how a Vortex Drop Shaft works is crucial in designing an effective system.
We are happy to share with you two case studies highlighting how the Hydro-Brake Drop® is used to achieve engineering excellence.
