Fox™ Valves

The Fox™ Valve system is designed to divert washdown and/or first flush stormwater runoff to trade waste to prevent pollution of downstream waterbodies.

A constant monitoring system can also be added to automatically divert spills and runoff with pollutant concentrations that exceed predetermined levels.

We currently stock the following three models;

 Demand Driven Washdown Diversion System (DD600)

Stormwater360’s Fox Demand Driven Washdown Diversion System is a unit that will divert any run-off to trade waste when a wash operation is taking place. When washdown ceases, the system will divert any run-off to fill the chamber and leave through the stormwater outlet. It is most important that the area is left clean as there is no protection for the environment when a wash operation is not taking place. Should the area not be able to be left clean the Fox First Flush System would be recommended (FF600).

First Flush Diversion System (FF600)

Stormwater360’s Fox Valve First Flush Diversion System is an effective control device for any unroofed washdown area automatically diverting wash water as well as the ‘first flush’ (if required) to sewer or treatment, whilst allowing unpolluted rain water to enter the stormwater network.

It is designed for use in areas where there is no guarantee that the wash bay will be left clean at the completion of a wash activity. Pollutants remaining on exposed areas can be dislodged by rain and carried into the stormwater network.

The Fox FF600 is designed to cleanse a site by capturing the initial runoff and diverting it to suitable treatment, as it is most likely that this initial runoff will carry with it any residual pollutants that have been left on the site.

Constant Monitoring Diversion System (CMS600)

When your site has the potential to have stormwater run-off that has been contaminated with water soluble products such as wines, milk or chemicals entering the waterways there is a need for a Stormwater360 Fox Constant Monitoring System.

The system will constantly monitor all site run-off for pollutant concentrations that exceed predetermined levels. If set levels are exceeded the system will divert to a holding chamber for containment, and diversion will continue until pre-set levels return and run-off will then be allowed to leave the site.
