Trench drains are linear drainage systems designed to collect and convey surface water or runoff through a continuous channel. Trench drains generally consist of a long, recessed trough, usually installed flush with the surrounding surface and typically covered by a removable grate. Water/runoff flows through the grate and along the channel to an outlet connected to the drainage system. Trench drains capture water along the entire length rather than at a single point, making them suitable for handling larger collection areas, like commercial kitchens, parking areas, loading docks, and outdoor recreation or pedestrian areas.
