Catch Basin System

Abstract

A drainage catch basin is formed from a rectangular trough with a planar upper rim defined by at least two opposite sidewalls and includes at least one inner wall forming a lower rim to define the gutter opening for flush mounting with the curb. The basin is covered by a top with a planar bottom that preferably includes a central circular manhole cover. The top is preferably formed by first providing a mold having a bottom and side frame of steel plates reinforced by a galvanized steel nosing and crossing rebar. The mold is then filled by concrete casting while installed on the catch basin trough to match the exterior color and/or finish of the adjacent sidewalk, street and/or curb.
