Claim:
1. A multi-compartment gabion assembly configured to treat stormwater, comprising: a plurality of adjacently positioned and integrally connected gabion cells, including at least one regular gabion cell and at least one corner gabion cell; characterized in that each regular gabion cell comprises: an outer gabion housing made of a rigid and malleable mesh material, the outer gabion housing defining four outer gabion housing walls and an outer gabion housing floor; further characterized in that each regular gabion cell includes: a first filter bag for filtering suspended solids out of the stormwater, wherein the first filter bag is positioned within the four outer gabion housing walls of the outer gabion housing and adjacent to the four outer gabion housing walls, and wherein the first filter bag defines a first filter bag floor made of a nonporous sheet material connected to four surrounding first filter bag walls, wherein the first filter bag walls are made of at least two different water permeable sheet materials; and two or more water permeable partitions vertically positioned within the outer gabion housing, wherein the two or more partitions segment the outer gabion housing into a plurality of different regular gabion cell compartments, with each regular cell gabion compartment containing a selected filter media that is different from the selected filter media of the other regular gabion cell compartments; further characterized in that each corner gabion cell comprises: an outer corner gabion housing made of a rigid and malleable mesh material, the outer corner gabion housing defining four corner gabion housing walls and a corner gabion housing floor; a second filter bag for filtering suspended solids out of the stormwater, wherein the second filter bag is positioned within the four corner gabion housing walls of the outer corner gabion housing and adjacent to the four corner gabion housing walls, and wherein the second filter bag defines a second filter bag floor made of a nonporous sheet material connected to four surrounding second filter bag walls, wherein the second filter bag walls are made of at least two different water permeable sheet materials; and two or more water permeable and generally L-shaped partitions vertically positioned within the outer gabion corner housing, wherein the two or more generally L-shaped partitions segment the outer gabion corner housing into a plurality of different generally L-shaped corner gabion cell compartments, with each generally L-shaped corner gabion cell compartment containing a selected filter media that is different from the selected filter media of the other generally L-shaped corner gabion cell compartments.
