Abstract: A stormwater filter comprising: a vessel having an inlet and an outlet; and a screen disposed within the vessel and arranged to divide at least part of the vessel into an upper section and a lower section. The stormwater filter further comprises: a flow splitter positioned adjacent the inlet of the vessel and/or a substantially vertical screen disposed adjacent the outlet in the upper section of the vessel. The flow splitter comprises an inclined leading edge and first and second deflecting surfaces extending from the leading edge. The first and second deflecting surfaces are angled relative to one another so as to direct incoming flow laterally away from an axis between the inlet and the outlet. The vertical screen comprises first and second screen portions which are angled relative to one another. The first and second screen portions are each hingedly connected to the vessel and are detachably coupled to one another at their distal ends.

Abstract: A drainage system, comprising a collector which is arranged to collect liquid and a drainage pipe having a pipe inlet that opens into the collector such that liquid collected by the collector drains through the pipe inlet. The drainage pipe is provided with a vent spaced away from the pipe inlet. The vent is arranged such that, when liquid collected by the collector occludes the pipe inlet, liquid flowing through the drainage pipe draws air into the drainage pipe through the vent.

Abstract: There is disclosed a water treatment apparatus for treating stormwater, the water treatment apparatus comprising a volume of filter media, a baffle and an inlet conduit. The baffle extends upwards from the volume of filter media and defines a pre-treatment zone on one side of the baffle and a treatment zone on an opposing side of the baffle. The inlet conduit opens into the pre-treatment zone and is separated from the treatment zone by the baffle. The baffle is configured to regulate a flow of stormwater received via the inlet conduit by controlling the passage of stormwater from the pre-treatment zone to the treatment zone.

Abstract: A drainage system, comprising a collector which is arranged to collect liquid and a drainage pipe having a pipe inlet that opens into the collector such that liquid collected by the collector drains through the pipe inlet. The drainage pipe is provided with a vent spaced away from the pipe inlet. The vent is arranged such that, when liquid collected by the collector occludes the pipe inlet, liquid flowing through the drainage pipe draws air into the drainage pipe through the vent.

Abstract: A treatment device for stormwater is provided that comprises a container which in use contains a growing medium and a hydrodynamic separator located within the container. The hydrodynamic separator comprises a separation chamber, an inlet duct extending from the outside of the container to the separation chamber, a solids outlet; and a liquid outlet that opens into the container. In use, liquid flow containing solids enters the separation chamber through the inlet duct and is caused to swirl within the separation chamber, thereby causing solids to exit the separation chamber through the solids outlet and liquid to exit the separation chamber through the liquid outlet and to flow into the growing medium.

Abstract: Embodiments of the invention provide a swing-out wall rack for mounting electrical equipment. The swing-out wall rack can include a frame configured to couple to a wall and a rack. The frame can include a vertical member and a horizontal arm. The rack can extend a width and a height. The rack can include a first side and a second side, the second side being opposite from the first side. The rack can further include a mid-point, the mid-point being approximately equidistant from the first side and the second side. The rack can be rotatably coupled to the horizontal arm of the frame substantially about the mid-point of the rack.

Abstract: Apparatus and associated methods may relate to a Self-Retracting Lifeline Connecting System (SRLCS) that securely attaches to a fall-protection safety harness, and further provides connections to a plurality of safety devices. In an illustrative example, the SRLCS may include a D-pad adapted for rear attachment to a back-pad of a safety harness. In some examples the D-pad may have webbing apertures through which two sections of webbing may be threaded in a criss-crossed manner. In some embodiments, the D-pad may provide an attachment for a first harness ring. In some exemplary embodiments, the D-pad may also provide a tunnel structure for routing a second harness ring therethrough. In an illustrative example, the tunnel may be located immediately adjacent the criss-cross location of the two sections of webbing, thereby permitting a carabiner to make use of the tunnel to capture the two sections of webbing.
