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.

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.

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. The frame comprises a thick portion and a narrow portion opposite the thick portion. The thick portion of the frame comprises the feed stream inlet. The filter material is positioned along a bottom surface of the frame and a portion of an upper surface of the frame that is opposite the feed stream inlet in the narrow portion of the frame. 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.

A storm water capture and filtration system may secure in a catch basin or other area subject to flows of water from streets, channels, and the like as a result of run off from storms. A filter system may include a capture portion including attachment mechanisms, a funnel, various supports, and a filter hanger designed and calculated to capture all water entering a storm water inlet and directing it toward a bag filter. A gap is provided between a funnel and filter hanger in order to provide accommodation for overflow, while an anti-backflow skirt on the filter bag resists flushing of captured pollution out of the bag in overflow condition.

A fluid flow control and debris intercepting apparatus for controlling the flow of fluid and the introduction of debris into the entrance of a conventional curbside storm drain of the character having spaced apart side walls that define a fluid flow channel through which fluid flows. Additionally, the apparatus senses the nature and extent of contaminants contained within the fluid.

A storm water runoff and erosion control device includes a rigid frame covered by a layer of mesh material. The frame defines an interior space that is filled with filtration material. The device may be configured as a wattle having an elongated frame with a triangular cross-section. The wattle may be extended along the contour of a hill to reduce erosion, or it may be placed at the entrance to a drainage inlet to slow the velocity of, and filter sediment and contaminants from, water entering the inlet. Alternatively, the device may be a compact filter that is a cube, cylinder, sphere, or other suitable geometry. A plurality of these compact filters may be placed in the basin of a storm water drain, and piled sufficiently high to cover the outlet from the basin. Thus, all the water in the basin must pass through the compact filters before exiting.

Stormwater runoff and erosion control devices include carpets or blankets, wattles, and compact drainage filters. A carpet or blanket is a sheet of mesh material having a border formed of a different material than the mesh material. Wattles and compact drainage filters include mesh material supported by a rigid frame. In preferred embodiments, the mesh material includes biochar or activated carbon. Blankets and carpets may be positioned above or suspended below drainage grates in a storm water runoff system, and held in place by magnets. Wattles may be placed on hillsides, or between concrete barriers and drainage grates. Compact drainage filters may be placed at the outlets of catchment basins.

Preferred embodiments of the invention provide improved catch basin filter system for maintenance and access. Preferred embodiments are composed of a diversion trough, a hinged pivot weir, weir to trough mounting brackets, under mounts, weir stops, a weir trash screen, a hole in the weir bottom section and a filter basket, wherein:

The present invention provides a storm water pretreatment chamber. The storm water pretreatment chamber includes: a base, an inlet sidewall, a first sidewall, a second sidewall, a filter sidewall, a handle, a first locking mechanism, a second locking mechanism, a first lifting cable, and a second lifting cable. Methods of treating storm water are also provided.
