• each said side column having inside and outside panels connected along a vertical front fold line and forming an acute dihedral angle for forming a front edge of said side column;
• each said outside panel being generally (flush with and parallel to a respective collection box side wall and thereby defining a flush side of said box against which said top can be poured;
• said inside panels converging generally rearwardly and inwardly with respect to said collection box and having respective top edges for directing storm water into said box;
• an upper crosspiece connected to said collection box top and extending between said side columns, said crosspiece having opposite ends connected to said side column upper ends;
• said upper crosspiece including a bottom flange mounted on said inside panel upper edges;
• said side columns and said crosspiece bottom flange forming an inlet throat converging into said collection box;
• each said side column outside panel having an upper edge at said side column upper end;
• each said side column inside panel having an upper edge located below said outside panel upper edge;
• each said side column inside panel upper edge being connected to said bottom flange at a respective upper crosspiece end;
• said upper crosspiece including a top flange mounted on said outside panel upper edges,
• said upper crosspiece including a front flange mounted on said outside panels below the upper edges thereof;
• said upper crosspiece bottom flange sloping rearwardly and downwardly from said front flange and having converging edges each aligned with and connected to a respective inside panel upper edge;
• a lower crosspiece extending between said side column inside panels and providing a back form for said apron;
• a medial column comprising a pair of panels folded along a medial column fold line located at the front of said inlet;
• said medial column being connected to said upper and lower crosspieces intermediate said side columns;
• each said side column outside panel having a respective notch located above said fold line and said inside panel upper edge;
• each said notch receiving a portion of a respective said crosspiece end;
• a trash bar extending across said throat and having opposite ends each mounted on a respective side column;
• a trash bar hanger mounted on said crosspiece and depending downwardly therefrom;
• said trash bar banger including a receiver receiving said trash bar;
• each said side column outside panel being located adjacent to a respective curb section;
• a pair of spacers each located between a respective side column outside panel and a respective curb section and adapted for accommodating relative movement therebetween;
• multiple reinforcing bars mounted on and extending rearwardly from said crosspiece;
• and
• said reinforcing bars being embedded in said collection box top.
