The Downstream Defender® is an advanced hydrodynamic vortex separator for the removal of sediment, oil and floatables from stormwater runoff.
The Downstream Defender® is proven to be more efficient than other structural treatment devices: it uses only 50% of the footprint of conventional structures and is the only deviced that has internal components proven to prevent pollutant re-entrainment (or washout).
• Control of sediment, floatables and petroleum products.
• Highway runoff
• SUDS schemes
• Wetland schemes
• Basin and pond protection
• Park & Ride schemes
• Watercourse and pond protection
• Industrial and commercial areas
• Vehicle maintenance washdown yards
• Quarry settlement ponds
The Downstream Defender® can be used to enhance or enable a SUDS solution. It can be used to protect other SUDS elements such as ponds or attenuation tanks.
The Downstream Defender® can be used in conjunction with our Hydro-Brake® Flow Control and Stormbloc® storage/infiltration system, to provide a complete SUDS solution which includes flow control, storage / infiltration and treatment.
The Downstream Defender® is efficient over a wide range of flows. It has no moving parts and requires minimal maintenance. It has been approved by regulatory agencies throughout the world.
