Abstract: A stormwater filter includes a receptacle having an open top into which stormwater is permitted to enter the receptacle and flow downwardly therein. A hydroponic garden section having a media bed is supported within the receptacle and in an elevated condition above the bottom of the receptacle so that a water sump compartment is disposed between the hydroponic garden section and the bottom of the receptacle. In addition, a discharge opening is defined within a sidewall of the receptacle in the water sump compartment and adjacent the hydroponic garden section, and a post-filtration flow control orifice is associated with the discharge opening for controlling the filtration flow through the media bed. In addition, a wick is associated with the media bed for drawing water upwardly from the water sump compartment for use by plants growing within the media bed.

Abstract: A gravitational separator for a drainage system includes a collection cavity within which drainwater is collected. The collection cavity includes an exit; and a baffle is strategically arranged within the collection cavity for isolating a boundary region of the cavity interior from the central region thereof and for directing the flow of drainwater which moves through the boundary region along a desired flow path. In addition, an outlet control structure is disposed over the mouth of the exit and includes a sidewall having an opening through which drainwater which enters the mouth of the exit must enter so that as the drainwater enters the sidewall opening and moves into the mouth of the exit opening, the direction of flow of the drainwater is altered through at least 90 degrees.
