A trench drain includes an open-faced channel that is polymeric with one or more integral metal frames molded into the sidewall(s) of the open-faced channel.

A storm water catch basin hazardous liquid valve that is automatically responsive to the presence of hazardous liquids in storm water run-off, the valve utilizing a hydrophobic barrier member to separate hazardous liquids from water. Collection of a sufficient amount of hazardous liquids across the hydrophobic barrier member initiates a float release member to seal off the catch basin. In the neutral or non-activated status, the storm water run-off enters the catch basin, passes through the valve assembly and out through the storm water conduit system in normal manner. When a hazardous liquid, such as oil, gasoline, chemicals, etc., is present in the storm water run-off above a threshold amount, the valve activates to close off the catch basin such that the storm water run-off is precluded from entering the storm water conduit system.

A catch basin system includes a first tube, a second tube, a basin, and an access port. The first tube is aligned along a first axis. The second tube is aligned along a second axis. The basin is disposed between opposing ends of the first and second tubes. The basin intersects the first and second tubes. The basin extends downward from the first and second tubes. The access port is aligned along a third axis. The access port is disposed above the basin. The access port is disposed between opposing ends of the first and second tubes. The access port intersects the first and second tubes. The access port extends upward from the first and second tubes. The access port is configured to provide access to the basin.

Embodiments of the present disclosure provide a stormwater drainage system including a multi-fit adapter for connecting at least one fluid pipe to a fluid basin. The multi-fit adapter may include a plate configured to be mounted on an outer surface of the fluid basin; and a plurality of concentric rings protruding from the plate. In disclosed embodiments, a curvature of the plate may correspond to a curvature of the outer surface of the fluid basin. In disclosed embodiments, each of the plurality of concentric rings may be configured to accommodate a fluid pipe.

A catch basin system includes a first conduit, a second conduit, a basin, and an access port. The first and second conduits are spaced-apart and are aligned along a first axis. The basin is disposed between the first and second conduits. The basin extends downward from the first and second conduits. The access port is aligned along a second axis, is disposed above the basin, is disposed between the first and second conduits, and extends upward from the first and second conduits. The access port is configured to provide access to the basin.

A stormwater treatment system and method for removing sediment, chemical pollutants, and debris from stormwater runoff by utilizing bioretention practices including physical, chemical and biological processes. Stormwater is directed into a primarily open-bottomed, multi-dimensional container whereby entrained sediment and other transportable materials are filtered and treated through a media filter layer consisting of inorganic and/or organic materials. A live plant (preferably a tree) situated within the container with roots resident in the media filter layer with the ability for expansion beyond the perimeter of the container through openings in one or more sidewalls. The treated water may be further conveyed beyond the perimeter of the container by additional openings and/or piping. A vertically positioned overflow/bypass/clean out piping apparatus may be included within the stormwater treatment system to provide additional water conveyance. Additional ancillary conveyance, filtration and storage facilities may be connected to the described stormwater treatment system as conditions warrant.

A catch basin system includes an upper housing and a lower housing. The upper housing defines an upper region of a first conduit and an upper region of a second conduit. The first and second conduits are aligned along a first axis. The lower housing is removably secured to the upper housing. The lower housing defines a lower region of the of the first conduit, a lower region of the second conduit, a third conduit disposed below the first conduit, a fourth conduit disposed below the second conduit, and a sump disposed between the third and fourth conduits and below the third and fourth conduits. The third and fourth conduits are aligned along a second axis. The first, second, third, and fourth conduits are each in fluid communication with sump.

A drainage apparatus for fluid runoff comprising one or more grates and a frame having a top portion configured to accommodate the one or more grates. The frame includes a first plurality of plates located within the frame and positioned below the one or more grates. One or more cross members are connected to plates of the first plurality of plates, each of the one or more cross members extends between at least two plates of the first plurality of plates. Each of the one or more grates is secured to a cross member of the one or more cross members.
