Abstract: A storm drain sediment filter that can be adapted to cover a catch basin and be held in place by a perforated grate. In one embodiment, the filter includes a frame including four L-shaped rigid members, each of which is provided with at least two spaced apart retaining members. The four L-shaped rigid members are arranged such that a rectangular frame is formed having a total of four overlapping sections. The retaining members engage one of the overlapping portions of the frame but slidably receives the other. No retaining ends are formed at the distal end of the slidably engaged L-shaped members to serve as a sliding boundary. Instead, the dimensions of the filter bag are such that the filter bag serves to define the maximum dimension of the frame and thereby maintain the overlapping L-shaped rigid members in slidable engagement with each other. A circular embodiment is also disclosed.

Abstract: An overpack salvage drum including a drum body and a lid. A bottom wall and side wall of the drum body cooperate to define an interior of the drum body. The lid is configured to close an open top of the drum body. The lid includes at least two independent lid threads to engage with corresponding independent drum threads provided on the drum body. The lid includes a plurality of alternating castellations having a flat inner facing side and castellations having an arcuate inner facing side, which can be interdigitated with castellations on another lid when two lids are stacked together, or can be used to lock with a drum body to rotationally secure a drum body relative to the lid when in a stacked arrangement. The lids include lugs and recesses, or rings that allow for secure stacking of the lids.

Abstract: A containment system includes a rotationally molded polymeric base unit in the form of a tub having an open top. The base unit includes a generally L-shaped rim at the open top comprised of an upwardly extending section that terminates in a cut edge and an inwardly extending section. The containment system also includes at least one perforated grate having a top side, a bottom side and a peripheral edge. The at least one perforated grate is supported, at least in part, by the inwardly extending section of the rim in such a manner that a container can be supported on the top side of the grate above the tub.

Abstract: Linkable workstations are provided that define a reservoir for containing liquid. The linkable workstations can be nested together in a compact vertical space. The workstations include a plurality of high rim portions and a plurality of low rim portions. The high rim portions on a workstation are configured to overlap a low rim portion of another workstation to link workstations side to side to form custom configurations. The workstations include overflow channels that allow for the sharing of the liquid containing capacity between linked workstations, and which can be selectively sealed to prevent fluid from flowing therethrough.

Abstract: An underground water-storage system that includes a sump having a base and sidewalls that cooperate to define an open-topped box that defines a reservoir, a plurality of plastic water matrices each defining a void space for receiving water, and a lid. The sump and lid are formed of a reinforced geomembrane material and include welds and are prefabricated in a location remote from an installation site of the underground water-storage vault more than two days prior to installation.

Abstract: A method of packing a package in an overpack salvage drum that includes a drum body for holding the package to be overpacked, a lid adapted to be rotatably threaded onto the drum body to seal the package held in the drum body therein, and a clip adapted to be operatively associated with the lid before the lid is rotatably threaded onto the drum body. The method includes placing the package into a drum body, operatively associating a clip to a lid that is adapted to be rotatably threaded onto the drum body, and rotatably threading the lid with the clip operatively associated therewith onto the drum body to seal the package therein, wherein the clip is adapted to break in preference to the lid and the drum body when the seal between the lid and the drum body is first compromised.
