Abstract: 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.

Abstract: The present disclosure is generally directed to processes and apparatuses for use in forming one or more flow channels within a prefabricated manhole assembly. More specifically, an exemplary apparatus embodying various aspects of the disclosure may contain a rigid channel form with a closed top portion, a curved bottom portion, a first end, and a second end. The apparatus may also contain a bung(s) removably positioned into an exterior hole through a sidewall of the prefabricated manhole that may receive one end of the channel form, the bung(s) interior end may further have an open-ended U-shaped slot. A sliding wedge may be used to engaged/disengage the flow channel form.

Abstract: A long-bar handling apparatus that delivers a desired size and shape of long-bar quickly and efficiently for shearing, bending, or further processing. The long-bar is loaded in slots in multiple rotating disk plates. A slot opening and closing mechanism, such as a pivot arm, is utilized to prevent loaded long-bar from falling out of slots during portions of rotation. The slot opening and closing mechanism opens on the top portion of rotation for loading and removing the long-bar for processing.
