A stormwater capture housing system designed to reduce greenhouse gas emissions by filtering solid waste from stormwater flow in roadways, transportation facilities, and pavement, while maintaining an optimal flow rate and enabling safe accessibility. The system comprises a housing unit with top grates that enable stormwater and solid waste to drain from the roadway into a sub-grade capture area formed by a screen weir and a screen box. The screen box ensures that the solid waste is collected while the water filters into a clean water area. The screen weir also filters solid waste and is further configured to allow for an overflow of stormwater and solid waste. Another section of the top wall has a filled grating configuration that allows for stormwater to drain without passing any solid waste to prevent flooding, also enabling access to the internal components of the housing system.

A skimmer for use in a manhole includes a frame and cladding. The frame includes an adjustable arc having an adjustable overall length and including an arced member, a first side member and a second side member. The arced member has a first end and a second end opposite the first end and defining a curve therebetween. The first side member is slidably adjustable relative to a first end of the arced member and selectively coupled thereto in one of a plurality of predefined first side member positions. The second side member is slidably adjustable relative to a second end of the arced member and selectively couplable thereto in one of a plurality of predefined second side member positions. The cladding covers a substantially entirety of one side of the frame.

Disclosed in the present application is a system for a storm water and traffic collector box culvert. The system may comprise a plurality of reinforced slabs with an upper slab that may be configured as a reinforced surface to collect storm water runoff. The plurality of slabs may be connected by a plurality of attachment mechanisms. Accordingly, the present system is directed to an environmentally friendly culvert design that can minimize the magnitude of earthworks required by traditional drainage systems while also providing increased drainage capabilities.

A drain system for water quality. The drain system may include one or more baffles. The one or more baffles may be arcuate in shape. The one or more baffles may include one or more openings therethrough. The one or more baffles may be offset in elevation. The one or more baffles may include one or more flanges projecting therefrom. The one or more baffles may be implemented in a flow-through manhole application.

A liquid treatment system is provided having a vault that contains a treatment chamber and an outflow chamber. The treatment chamber may have a filtration media layer containing media that treats liquid as it descends through the filtration media layer, where it will accumulate in a porous layer or open space. The liquid will then be directed through the plurality of pipes to the outflow chamber, where the treated liquid is further directed to outside the system. Accumulated debris settled at the bottom of the treatment chamber may be flushed out by a spray bar.

Disclosed is a trash collector for drainage channels. The trash collector includes a main frame provided with engaged parts engaged with engaging protrusions of an inlet of a drainage channel and a penetration part having one side vertically penetrated, an opening and closing plate mounted in the penetration part so as to selectively open and close the penetration part depending on a load of water introduced through the inlet of the drainage channel, and a hinge shaft interposed between the main frame and the opening and closing plate so as to axially rotate the opening and closing plate. A base plate of the main frame and the opening and closing plate have a designated height so that fallen leaves and road trash accumulated and gathered on the base plate and the opening and closing plate may be sufficiently suctioned by suction force of a street cleaning vehicle.
