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.

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.

Adjustable filter basket for a storm water drain system

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.
