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 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.

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 drain filter (1) that is easily installable and removable from a curb style water inlet (20) of a storm drain (23) and that is effective in preventing debris and unwanted substances from entering storm drains by collecting the debris while allowing water to pass through into the storm drain.

A filtration apparatus for installation in a catch basin vault is described. A perforate support plate includes a retractable basket that lies below an opening in the support plate and is positioned below a manhole. Water flowing into the system flows onto the support plate and into the basket, which traps debris. The basket is slidable from an in-use position where the basket is positioned to screen debris flowing into the vault, and a cleanout-position in which the interior of the vault is accessible so that the vault may be cleaned. When the vault needs to be cleaned, the manhole cover is removed to allow workers to have access to the interior of the vault. The workers may clean out the basket, and then slide it out of the way so that they have access to the vault interior.
