20090134081 | Adjustable filter basket for a storm water drain system - A nutrient separating filter basket apparatus for a storm water drain system has an adjustable filter basket installed in a storm water drain pipe system to receive storm water runoff therethrough. The filter basket collects organic materials, such as grass clippings, leaves and tree stems therein and is adjustable for different ground water levels. | 05-28-2009 |
20090152181 | Backwashing filter basket - The present invention is for a self-cleaning filter basket for an overflow structure for a retention pond or storm water system. The filter basket is attached to the overflow structure over the outlet weir so that floating debris, such as trash, leaves, glass clippings, tree stems, and the like, is captured by the filter basket while sand, gravel and non-floating materials pass through the filter screen. The self-cleaning filter basket screens are cleaned by water, such as rain water, being directed through openings in the top of the filter basket to impinge against the angled screen sides in the filter basket to flush accumulated debris therefrom. | 06-18-2009 |
20090166279 | Storm water filter system having a floating skimmer apparatus - A storm water filter box has a floatable skimmer apparatus for preventing floatable debris from entering the filter box outlet. The filter box has an inlet and an outlet and an inlet filter located in the filter box housing. A portable skimmer is positioned in the box between the inlet and outlet and will rise and fall with the water level in the filter box to keep the top of the skimmer above the water level and force the storm water passing through the filter box under the floatable skimmer thereby blocking floatable debris from entering the filter box outlet. | 07-02-2009 |

The filter box has an inlet and an outlet and an inlet filter located in the filter box housing. A portable skimmer is positioned in the box between the inlet and outlet and will rise and fall with the water level in the filter box to keep the top of the skimmer above the water level and force the storm water passing through the filter box under the floatable skimmer thereby blocking floatable debris from entering the filter box outlet. | 07-02-2009 |
20100032363 | Floating skimmer apparatus with up-flow filter - The present invention is a storm water filter system for filtering floatable debris and non-floating pollutants from storm water passing through a storm water drain system. The storm water filtering system has a floatable skimmer therein for capturing floatable debris and trash from the storm water and a separate filtration system to filter non-floatable pollutants from water passing therethrough. | 02-11-2010 |
20100078370 | Floating baffle panel and filter apparatus - The present invention is a storm water filter system for filtering floatable debris and non-floating pollutants from storm water passing through a storm water drain system vault. The storm water filtering system has a vault having chamber having a wall between the inlet thereto and the outlet therefrom. The wall has a filter passageway therethrough for filtering the storm water and a floatable baffle panel covering a second passageway therethrough for capturing floatable debris and trash from the storm water. Storm water entering the vault inlet passes through a filter element and out the outlet and also can pass under the floating baffle panel when the floatable baffle panel is floated to a raised position to thereby prevent storm water from accumulating on the inlet side of the wall. | 04-01-2010 |
20100230338 | Floating skimmer and filter apparatus - The present invention is a storm water filter system for filtering floatable debris and non-floating pollutants from storm, water passing through a storm water drain system vault. The storm water filtering system has a vault having chamber having a floating skimmer panel between the inlet thereto and the outlet therefrom. The skimmer panel has a filter passageway therethrough for filtering the storm water while the floatable skimmer panel captures floatable debris and trash from the storm water. Storm water entering the vault inlet passes through a filter element in the skimmer panel and out the vault outlet and also can pass under the floating skimmer panel when the floatable skimmer panel is floated to a raised position to thereby prevent storm water from accumulating on the inlet side of the wall. | 09-16-2010 |
20110168612 | Storm water filter basket with floating bypass panels - The present invention is a nutrient separating baffle box having a screened filter basket therein for a storm water drain system and especially to a screened filter basket having floating bypass panels to allow the capture of floating debris in the filter basket and when the basket cannot pass enough water flow therethrough to thereby allow bypass of storm water while retaining floating debris in the filter basket. | 07-14-2011 |
20120043266 | Grate cover apparatus - The present invention relates to a temporary grate cover apparatus for placement over a storm water grate to filter sediment and trash from entering the storm drain during a construction project. | 02-23-2012 |
20140158598 | STORM WATER VAULT HAVING AN ARTICULATED FLOATING SCREEN FILTER SYSTEM - A storm water nutrient separating vault has a floatable filter basket therein for collecting debris entering the storm water filter vault which basket rises and falls with the water level in the vault. The floatable filter basket has a pair of swiveling trucks attached thereto. Each truck is supported on a generally vertical track mounted to a wall of the vault on one side of the vault's inlet and has a plurality of rollers riding in the track. The floatable filter basket can therefore swivel or tilt while rising or falling with the water level in the vault to maintain an opening in the nutrient collecting basket in front of the vault's inlet for capturing floating debris in the storm water entering the vault. | 06-12-2014 |
20140352729 | STORMWATER VAULT APPARATUS AND SERVICING PROCESS - A stormwater vault and a process for servicing the stormwater vault speeds the process of cleaning a stormwater vault. The stormwater vault has a built in liquefaction system for liquefying settled debris in the vault which works together with a sloped or angled floor in the vault. The settled debris is flushed toward the inlet to a vacuum removal line inserted into the vault through an access opening for removing the settled debris from the vault. | 12-04-2014 |
