Vortechs™ is a below-ground, engineered stormwater treatment device that combines swirl concentration and flow controls into a single treatment unit.

Hydrodynamic Separator for Shallow Applications
The design also allows for easy inspection and unobstructed maintenance access. With comprehensive lab and field testing, the system delivers proven results and site-specific solutions.
Pre-cast models can treat peak design flows up to 700 L/s; cast-in-place models handle even greater flows. A typical system is sized to provide an 80% load reduction based on field and laboratory-verified removal efficiencies for varying particle size distributions such as 50-micron sediment particles.
The Vortechs™ system’s swirl concentrator and flow controls work together to create a low energy environment, ideal for capturing and storing fine particles and other pollutants of concern.
