Abstract: A catch basin stormwater filtering apparatus includes a support frame and a filter medium supported by the support frame. The support frame includes a planar upper plate and a planar lower plate disposed below and in close proximity to the upper plate. The upper and lower plates have substantially the same outer dimensions, and the support frame defines a central opening. The filter medium is in the shape of a basket and includes lateral side walls of which adjacent walls are joined together, and a bottom wall, the lateral side walls defining a top opening which is disposed in alignment with the central opening of the support frame. The filter medium also includes a flange that extends outwardly from the lateral side walls at the top opening of the filter medium. The flange is interposed between and adhesively joined to the upper plate and the lower plate of the support frame.

Abstract: An expansion ring mountable in a storm drain for supporting a filtering apparatus includes a ring-shaped expansion member having an adjustable diameter which is cut transversely to define two open end portions thereon which face each other and which are separated from each other by a predetermined distance to define a gap therebetween. A wedge assembly is positioned at the gap between the open end portions of the expansion member and is adjustable to increase the diameter of the expansion member. When the wedge assembly is adjusted to increase the diameter of the expansion member, the expansion member tightly engages a side wall of a portion of the storm drain in which the expansion ring is mounted to secure the expansion ring, and a filtering apparatus supported thereby, in a desired position.

Abstract: A stormwater treatment system includes water treatment media that defines a helical flow path within a conduit. The water treatment media may include a plurality of helical water treatment media components that are constructed and arranged to seal against an inside surface of the conduit. The individual helical water treatment media components may be installed in situ within the conduit when the conduit is positioned within a chamber having an access opening, and periodically removed and replaced by passing the components to the access opening. The components further may have a flexible frame, which allows the water treatment media to dynamically adjust to swelling of the filtration media and other forces that may occur during use. The performance of the system may be adjusted by adjusting the helical pitch of the helical water treatment media components.

Abstract: A system for treating runoff water from a plastic container includes a tray having at least one drainage hole defined in a lower surface thereof. Remediation media is positioned within the tray for absorbing at least one nutrient from the runoff water. A container support member may be connected to the tray for supporting a number of potted plants above the space within the tray that is occupied by the remediation media.

Abstract: A method of mounting a grate adapter unit beneath a stormwater collection grate includes steps of providing a grate adapter unit having a plurality of outwardly extending mounting flanges, each mounting flange being adapted to fit a different size commercially common stormwater collection grate. The grate adapter unit is trimmed, either at the factory, at the contractor's facilities or at the installation site, at the desired location to select a desired one of the mounting flanges that is appropriate for the collection grate to which the grate adapter is being fit. The grate adapter unit is then mounted beneath the stormwater collection grate using the selected mounting flange. A stormwater remediation unit may be pre-mounted to a lower end of the grate adapter unit or mounted to the lower end after installation.

Abstract: A storm sewer insert for use in a storm water drainage system includes a collection basin that has an upper inlet opening, a lower outlet opening and at least one overflow bypass opening defined therein. A filter assembly is preferably positioned in the lower opening of the collection basin for filtering storm water that is held in the collection basin. Advantageously, adjustable mounting structure is provided for mounting the collection basin to an inlet opening of a storm sewer or catch basin. In addition, a mosquito barrier is preferably provided for reducing mosquito passage through the bypass opening.

Abstract: An insert for a storm water treatment system includes an elongated baffle member that is configured to be mounted within a substantially upright storm water drain basin so as to separate the interior space of the drain basin into a first compartment that communicates with an inlet opening of the drain basin and a second compartment that communicates with an outlet opening of the drain basin. A predetermined primary flow path is defined in the baffle number between the first and second compartments near a lower end of the baffle member. Treatment material is positioned, optionally in cartridge form, in a lower end of the second compartment so that storm water in the primary flow path will be directed through the treatment material in order to remediate possible contamination of the storm water. The system is designed in order to facilitate retrofitting of existing storm water drainage infrastructure and for original installation. A method of treating storm water is also disclosed.

Abstract: A system for treating storm water in situ within a storm water drainage system includes a process chamber and treatment material that is contained within the process chamber. Preferably, the treatment material is a material that is effective in removing heavy metals from storm water, such as zeolite. A first passageway is provided for admitting storm water from the storm water drainage system into the process chamber. A second passageway is provided for returning storm water from the process chamber back to the storm water drainage system. Also disclosed is a method of retrofitting conventional storm water drainage systems so as to render them capable of effectively removing heavy metals from storm water passing therethrough.
