An inlet filter and method of use are disclosed. In one aspect, the inlet filter comprises a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame is configured so an exterior of the frame is shaped like a wedge. In another aspect, the method comprises inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet. In a third aspect, a system comprises a plurality of inlet filters configured to be coupled together to filter a feed stream to a storm sewer inlet. The system can be configured so that the width of the plurality of filters is adjustable. For example, a first inlet filter and second inlet filter can be slidably engaged with a connecting filter.

A stormwater treatment system and method for removing sediment, chemical pollutants, and debris from stormwater runoff by utilizing bioretention practices including physical, chemical and biological processes. Stormwater is directed into a primarily open-bottomed, multi-dimensional container whereby entrained sediment and other transportable materials are filtered and treated through a media filter layer consisting of inorganic and/or organic materials. A live plant (preferably a tree) situated within the container with roots resident in the media filter layer with the ability for expansion beyond the perimeter of the container through openings in one or more sidewalls. The treated water may be further conveyed beyond the perimeter of the container by additional openings and/or piping. A vertically positioned overflow/bypass/clean out piping apparatus may be included within the stormwater treatment system to provide additional water conveyance. Additional ancillary conveyance, filtration and storage facilities may be connected to the described stormwater treatment system as conditions warrant.
