Abstract: Stormwater inlets and stormwater inlet seals are disclosed. The stormwater inlet seal can include a first section and a second section. The first section and/or second section at least partially defines an opening in the stormwater inlet seal. The first section can be pivotally connected to the second section about an edge of the first section. The first section can be moveable between a first position in which the first section is biased towards a closed position to direct fluid towards the opening and a second position which allows access to the inlet. A stormwater inlet with a first section that is pivotally connected to a sidewall is also disclosed.

Abstract: A method of removing sediment from fluid flow within a storm water drain pit by deflecting flow entering the pit towards the side walls of the pit by one or more deflectors. This reduces the energy of the fluid flow and promotes settling of sediment within the catch pit. Each deflector is preferably of a concave form and may be located in a storm water drain pit bag or suspended. A removable catch basin receptacle for a storm water drain pit includes a container has a low flow outlet defining a fluid path for fluid at a first level within the container to a second level, higher than the first level, outside the container. An overflow path provides a fluid flow path out of the container at a level higher than the first or second level.

Abstract: A storm water drain filter including a collapsible frame supporting a filter bag. The filter may be installed in a stormwater drain pit to capture contaminants and particulate matter before it enters a stormwater drain. The collapsible frame is light weight, compact, simple and inexpensive. The filter bag is secured to the frame so as to maintain its shape and avoid deformation. There is also disclosed a method of installing a stormwater drain filter in a stormwater drain pit to provide an effective seal between the stormwater drain filter and the pit.
