Patent ID: 8715507

Claim:
A system for baffling at least one stormwater flow-path, comprising: a flow-through stormwater sump, the flow-through stormwater sump having a bottom and defining an inlet opening, an outlet opening and a top access opening; an inlet conduit coupled to the flow-through stormwater sump at the inlet opening; an outlet conduit coupled to the flow-through stormwater sump at the outlet opening; and a flow-path baffle disposed in the stormwater sump and raised above a bottom of the stormwater sump, the flow-path baffle being substantially planar and defining at least one opening configured to partially disperse stormwater flowing from the inlet opening between an upstream side of the stormwater sump adjacent the inlet opening and a downstream side of the stormwater sump adjacent the outlet opening to dissipate energy of downward flows of the stormwater, wherein the at least one opening is sized such that between 40% and 50% of a face of the flow-path baffle is open, with, the flow-path baffle oriented such that a centerline of the inlet conduit intersects a major plane of the baffle at a point above a bottom of the baffle, and a centerline of the outlet conduit intersects the major plane at another point that is also above the bottom of the flow-path baffle, the flow-path baffle disposed in the stormwater sump in a direct impingement inlet flow-path of the inlet conduit such that, during the storm flow, the inlet flow-path extends to the flow-path baffle to intersect with the major plane, with a baffle area of the flow-path baffle being larger than a cross-sectional area of the inlet flow-path of the stormwater flow-path, and the flow-path baffle is disposed in the stormwater sump in a direct impingement outlet back-flow-path of the outlet conduit such that, during the storm flow, the outlet back-flow-path extends to the flow-path baffle to intersect with the major plane, with the baffle area being larger than a cross-sectional area of the outlet back-flow-path of the stormwater flow-path.
