How it Works
Stormwater enters the chamber via an inlet pipe or inlet grate and is directed
between the filter modules to the sump of the chamber (brown arrow).
Gross debris and sediment settle out in the sump, while oil and floatables rise to
the surface of the water.
As water fills the chamber, the flow is directed up through the angled screen
(yellow arrow) preventing larger material from reaching the filter media.
Flow distributing media spreads the flow evenly across the filter media as the
water level increases within the chamber (green arrows).
Treated water enters a conveyance channel at the top of the filter module, where
it is directed to the outlet module and passes forward to the outlet pipe (blue
arrows).
Excess flows associated with extreme storm events are discharged directly to
the outlet module via a siphonic bypass, which incorporates a floatables baffle to
prevent the discharge of oils and floatable material.
Following the storm event, water drains out of the chamber through the patented
drain down port. This backwashes the filter media and leaves it dry between
storm events, preventing pollutant leaching and media degradation.
