Partitioned water treatment systems with vertical filtration units

1. A partitioned water treatment system comprised of a box configured for installation into a flow stream of surface runoff water conveyance infrastructure (SRWC infrastructure), the box possessing a ceiling, a floor, two lateral walls, two endwalls, an inflow opening, an outflow opening, a discharge chamber wall, and one or more collection rail(s), wherein:

the discharge chamber wall is in sealed connection with the floor and the two lateral walls, but not the ceiling and a separation chamber wall is in sealed connection with the floor, one of the endwalls, and the discharge chamber wall, but not the ceiling, such that the discharge chamber wall and the separation chamber wall partitions the box into a separation chamber that abuts the inflow opening, a filtration chamber, and a discharge chamber that abuts the outflow opening,

the inflow opening is: i. positioned in the ceiling, one of the two lateral walls, or one of the two endwalls; and ii. configured for achieving sealed, fluid communication with SRWC infrastructure upstream of the partitioned water treatment system,

the outflow opening: i. positioned in the floor in or in proximity with the floor in one of the two lateral walls or one of the two endwalls; and ii. configured for achieving sealed, fluid communication with the SRWC infrastructure downstream of the partitioned water treatment system,

each of the one or more collection rail(s) comprises: i. a duct that extends from the discharge chamber to the filtration chamber, sealingly through the discharge chamber wall, and ii. one or more filter assemblage(s):

the one or more filter assemblage(s) comprising a vertical filter, a filter opening in the duct, and a coupler that mounts the vertical filter on the duct and places the vertical filter and the filter opening in sealed, fluid communication,

wherein the separation chamber is partitioned into a primary and secondary separation chamber by a partition wall which is configured to allow water entering the inflow opening to flow into the primary separation chamber, over separation chamber partition wall, into secondary separation chamber and in the process settling out sufficiently dense and heavy waterborne sediment and debris,

wherein the vertical filter of at least one of the one or more filter assemblage(s) comprises a sheet of filter material formed into a cylinder closed by a top end that is water impermeable and a bottom end that is water impermeable a part from an opening through which water can flow, and wherein the coupler is adapted to place the opening in the bottom end of the vertical filter in sealed, fluid communication with the filter opening of the at least one of the one or more filter assemblage(s);

wherein the sheet of filter material is selected from the group consisting of a plastic, a paper, a fiberglass, and a combination thereof;

wherein the sheet of filter material comprises back and forth folds that form a series of pleats;

wherein the coupler of at least one of the one or more filter assemblage(s) is adapted to removeably mount the vertical filter on the duct;

the duct comprising an exit opening in the discharge chamber and configured such that: i. each of the one or more filter assemblage(s) are positioned in the filtration chamber, and ii. the duct is water impermeable a part from the exit opening and the filter opening(s) of each of the one or more filter assemblage(s), and

the collection rail is operative to allow water to flow from the filtration chamber to the discharge chamber by passing through at least one of the one or more filter assemblage(s), the duct, and the exit opening,

the top of the discharge chamber wall is positioned in the box such that in conditions of:

i. low to moderate water flow through the system, a flow path of water is from the inflow opening into the separation chamber, over the separation chamber wall into the filtration chamber, through at least one of the one or more collection rail(s) into the discharge chamber, and through the outflow opening, and

ii. high water flow through the system, an additional flow path of water is from the inflow opening into the separation chamber, over the discharge chamber wall into the discharge chamber, and through the outflow opening.

2. The partitioned water treatment system of claim 1 , further comprising a cap or a plug sealingly mounted on the exit opening, wherein the cap or the plug is water impermeable apart from one or more aperture(s) sized, individually or in aggregate, to control a rate of water flow through the duct that is less than a maximum rate of water flow through at least one filter of the one or more filter assemblage(s).
