Typical trench drain sizing considerations

In order to size a trench drain system (length and width), the
following information is needed:

 1. Total length of the trench drain (feet or meters).

 2. Length and width of the surface area draining into the trench (feet or meters).

 3. Surface area type – concrete, pavement, asphalt, etc.

 4. Rainfall intensity (inches per hour or mm per hour) of the area where the trench drain will be installed.

 5. Slope or ground along the trench drain (%).

 6. Perpendicular slopes to trench drain (%).

 7. Location of and number of outlets along the trench
drain run.

 8. Any slab depth height restrictions.
