ABSTRACT:
A skimmer cover for a secondary dispersement system orifice in a storm water catch basin prevents inflow of floatable materials, and especially hydrocarbons from motor vehicles, from entering the orifice. The orifice is defined in a neck extending spacedly above the bottom of the catch basin surface to carry the skimmer cover. The skimmer cover provides a top with a peripheral skirt diametrically larger than the neck and supported on the neck to depend therebelow to a point spacedly above the catch basin bottom surrounding the neck. An internal cylinder depends from the cover top within the skimmer cover skirt and defines plural spaced orifices to allow fluid passage therethrough and into the orifice defined by the neck. A depending fastening structure having opposed pivotal lever arms moved by a medial screw therebetween is carried by the skimmer cover top to allow releasable fastening of the skimmer cover within the neck orifice for positional establishment and maintenance of the skimmer cover thereon.
