The dual chambered PIT BULL will attack your stormwater issues by providing multiple filtration options in one unit.
As water enters the first chamber, sediment settles and is retained there. The second chamber is then set up with a filtering media that filters the water. Simply choose the right filtering media for your specific needs:

Filter Media Options
Oil/Hydrocarbon Filter Media- Used to remove oil, grease and other hydrocarbons
Phosphorous Filter Media- Excellent for removal of phosphorous where fertilizer and animal waste runoff is a concern
Activated Carbon Filter Media- Excellent "polishing media" that helps to remove certain chemicals, hydrocarbons and odors
Heavy Metal Filter Media- Custom filter media blend helps remove zinc, lead, copper and other harmful, heavy metals
