Abstract
A drainage channel system is disclosed which is characterized by a plurality of drainage channel segments (30) of progressively greater length adapted to be interlocked end-to-end. Each channel segment (30) comprises a pair of opposing, spaced-apart sidewalls (31), (32), a bottom wall (33) connecting the sidewalls (31), (32) adjacent one end and a top opening opposite bottom wall (33) defining a fluid entrance adapted to receive a grate (37). A sidewall extension (10) is provided for being mounted on top of each of the sidewalls of channel segment (30) along at least a part of the length thereof to effectively increase the total depth of each channel segment (30) and increase the length of a continuously and progressively sloping run of the drainage channel system.
