Products

Customise the capture and retention of sediment, oils and floatables from storm water runoff over a wide range of flows in a small footprint.

The Downstream Defender® Select is the new generation of advanced hydrodynamic vortex separator for treatment of urban surface water runoff. Its customisable performance and extended range of chamber sizes allows engineers to tailor their drainage designs to meet specific pollutant removal standards.

The Downstream Defender® Select also offers easier installation with much more flexibility of pipe sizes and connections and can accept up to three inlets.

Benefits:

  • Engineers can meet storm water quality objectives with customisable performance and the ability to work alongside other treatment solutions
    such as ponds, swales and constructed wetlands
  • The Downstream Defender® Select is offered in an extended range of chamber sizes helping engineers match flow rates and removal rates more
    cost-effectively
  • The Downstream Defender® Select can accept up to three inlets and a wider range of connecting pipe sizes, helping to make design and installation on-site easier and cheaper
  • Maintenance is easily and safely undertaken from the surface. An additional option to add Hydro-Logic® Smart Maintenance for automated
    alerts is available as standard making it more cost-effective
  • An option for improved retention of captured hydrocarbons (oils) can also be added

 

Application Information:
Treats runoff from any impermeable surfaces including highways, car parks and industrial areas. Also widely used to control siltation upstream of wetlands, ponds and basins, for example, as an alternative to a sediment forebay.

 

Material: Plastic internals in either a concrete or plastic chamber.
