A connector pipe screen device configured for mounting on a water conduit includes an expandable ring mounting assembly, the expandable ring mounting assembly being configured to be engagable with and securable to the conduit near or at an axial end of the conduit at which a conduit opening is disposed, a back plate mounted on the expandable ring mounting assembly and a front cover mounted on the back plate. The front cover has a perforated portion defining a multiplicity of openings formed therein to allow water to pass through the perforated portion and to prevent debris carried by the water from passing through the perforated portion.

A headrace system 1 improving a scum generation function of the headrace distributing and supplying raw water to a sedimentation basin provided in a sewage treatment plant to contribute to energy savings in the sewage treatment plant as a whole and contribute to solving environmental problems, which is provided with a buoyant imparting means 20 configured with including an ejector 22, in a side in which the raw water of a headrace body 2 to which the raw water is supplied or in the raw water flowed into the headrace 2 to impart buoyant force to solid matters contained in the raw water, and scum removing means 4, 8, 9, 10, 40a, and 40b removing scum S floating on a water surface of the headrace body 2.

Stormwater and fluid management runoff systems, apparatus, and methods for containing and filtering runoff may be provided. In one implementation, a stormwater management box for managing stormwater runoff may be provided. The stormwater management box may include a top plate and a base plate having a plurality of spaced apart columns positioned therebetween. The stormwater management box may include one or more side panels positioned between the top plate and the base plate, each side panel comprising a cover. The stormwater management box may also include a truss, the truss running perpendicular to the vertical plane of the one or more side panels and fitting within a vertical space between an upper surface of the bottom plate and a lower surface of the top plate.

A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

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.
