Abstract
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.
