Catch basin

Abstract

The invention describes a catch basin having an inlet zone and an outlet zone separated by a vertical baffle wherein: (i) the vertical baffle is positioned in such a manner that liquid is permitted to flow from the bottom of the inlet zone to the bottom of the outlet zone; (ii) the vertical baffle provides an inner wall for the outlet zone; and (iii) the outlet zone has an outer wall parallel to the vertical baffle, the outer wall having an outlet port at its upper end, the improvement comprising: locating a series of at least three alternating baffles in the outlet zone, these alternating baffles being parallel, and bearing a spaced relationship, to each other; the even numbered baffles in the series being attached at right angles to the vertical baffle; the odd numbered baffles in the series being attached at right angles to the outer wall; and each baffle in the series extending just beyond the midpoint between the vertical baffle and the outer wall, the first baffle in the series being attached to the bottom of the vertical baffle and the last baffle in the series being attached to the vertical baffle at a point below an imaginary line running from the bottom of the outlet port to the vertical baffle, the imaginary line being parallel to the alternating baffles.
