HOW IT WORKS

As stormwater enters the inlet through the grate it passes through an absorption Storm Boom located around the top perimeter.
|
Throughout the entire storm event, stormwater continues to come in contact with the Storm Boom and then flow into the lower filtration chamber, adjacent to the fine sieve size screens. |
As the storm event increases in intensity the water level in the Grate Inlet Skimmer BoxTM rises to a level adjacent to the medium sieve size screens and the turbulence deflector. |

|
As the storm event increases in intensity to that of high flow storm event, the water level in the Grate Inlet Skimmer BoxTM rises to a level adjacent to the coarse sieve size screens above turbulence deflector.
|
If the storm event creates an extremely high flow rate into the inlet which exceeds the flow through all the screens, the water flow can bypass the filtration screens through skimmer protected bypass openings near the top of the Grate Inlet Skimmer BoxTM.
|
After The Storm Event: The stormwater drains completely out of the Grate Inlet Skimmer BoxTM after the storm event. The debris collected in the unit is stored in a dry state.
