Product Detail


Concrete based oil and sediment separator for wastewater and storm water applications.








Typical applications of the Downstream Defender include streets and roadways, car parks, industrial sites, service stations, shopping centres and mine sites.

The separator is based on a hydrodynamic vortex (gravity) process which removes sediments and oils from storm water runoff. It removes fine particles (less than 100 micron) from relatively high treatment flow rates.

The isolated storage zones within the unit prevent remobilization of captured pollutants ensuring that the performance of the unit remains the same regardless of whether the unit is empty or approaching its storage capacity.

The defender has a small footprint and no moving part. It is a precast unit which is easy to install or retrofit and is low maintenance. The product is sold in Australia under licence from Hydro International, a UK and USA based company.
