  • Storm drain baffle to decrease sediment washout
    Patent number: 8715507
    Abstract: Some examples includes a 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, the flow-path baffle being substantially planar and defining a plurality of openings, the flow-path baffle oriented such that a centerline of the inlet conduit intersects a major plane of the baffle at a point and a centerline of the outlet conduit intersects the major plane at a further point, the flow-path baffle disposed in the stormwater sump in a direct impingement inlet flow-path of the inlet conduit and a direct impingement outlet back-flow-path of the outlet conduit.
