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.

A system and method for an underground stormwater storage system which may comprise a pit, a structure, and a liner. The structure may be disposed within the center of the pit and surround by the porous backfill and wherein outlets are disposed on the crown of the structure. A liner may form the outer layer of the pit. A method for releasing stormwater may comprise capturing stormwater from a surface, containing the stormwater within a structure, releasing a volume of the stormwater from the structure and draining an additional volume of the stormwater from the crown of the structure from an outlet when the structure is capturing more stormwater than it is releasing.

Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system. A flow spreader having a triangular shape with straight sides, or concave sides or convex sides can split incoming water to pass into dual screen filtration systems. Additionally, an upwardly angled debris ramp above a downwardly angled screened defector can be located on both sides of the flow spreader to help direct debris and trash into dual screened boxes. The system can also include components selected from a shelf beneath the spreader, at least one baffle, skimmer, deflectors, media filtration and hydroslide water pressure lines with spray heads for cleaning debris on a sloped floor.

A solid waste interceptor for a drain includes a tank for collecting waste water therein, the tank having a waste water inlet and a waste water outlet, a tray housing a strainer basket being slidably mounted within the tank, in the manner of a drawer, to be moved between a closed position in which the strainer basket receives waste water from the waste water inlet, and an open position in which the tray extends from the tank to provide access to the strainer basket to facilitate emptying of collected solid waste therefrom. The tray is provided with a drain outlet for delivering waste water passing through the strainer basket into a sump of the tank, and the drain outlet spigot is adapted to abut a front wall of the tank when the tray is in its open position to delimit the open position of the tray.
