发明名称 Water resistant hatch and hood
摘要 A hood that mounts around an outlet of a catch basin with a cover having a proximal end and distal end; the proximal end being pivotally attached to the hood. The cover pivots between a closed sealed position that substantially prevents water born contaminants from passing through the access opening and an open position that allows access to the access opening. The cover is made from a flexible material to allow the cover to be lifted from the closed sealed position in a substantially vertical path that allows access to the outlet of a catch basin.
