A slot drain is a linear drain used to evacuate water, runoff or liquids in a facility. The difference between a slot drain and the traditional trench drain is that the slot drain has no grating.

This increased flow velocity positively affects how the linear drain functions, making it possible to use a smaller diameter smooth pipe to carry the same amount of water as a larger culvert metal slot drain.
