1. A biofilter chamber comprising:
one or more outer side walls defining a first chamber;
a first media filtration bed disposed within the first chamber and enclosed by one or more permeable inner side walls, the inner side walls being separated from the outer side walls by a void area for receiving an influent; whereas
a permeable collection tube is disposed within the first media filtration bed configured to collect the influent from the first media filtration bed as filtered influent; the permeable collection tube, containing within it, a flow control riser,
said flow control riser contains one or more orifices, arranged vertically along the flow control riser, and a bottom seal flange, such that filtered influent entering the permeable collection tube must pass through the one or more orifices in the flow control riser at a rate less than a flow rate capacity of the permeable collection tube, and
said permeable collection tube and flow control riser are connected to a horizontal chamber outlet tube, said horizontal chamber outlet tube protruding through a chamber wall opening to an outside of the first chamber, the chamber wall opening configured to receive the filtered influent from the permeable collection tube via the chamber outlet tube.
