3000 Series trench drain at airport terminal

Airports require trench drains with secure lock downs because a loose bolt can be sucked into the plane's engine or propelled at high speeds by the engine blast.  Though trench drain systems at airport facilities cover a broad spectrum they all share the signature impact resistance and lock downs that mark airport trench drain applications.

Pro Tip:

  • Slotted drains are popular at airports because, without grates, they have the largest percentage of open area and pose no debris hazards on the tarmac.

airplanes in rowCounty airports

County airports support small single and twin prop aircrafts. Incorporate trench drain systems on taxiways and in front of the hangar doors.  Because loads are light (Class D), these drains tend to use ductile or cast iron grates without additional reinforcement.  County airports commonly use 4” wide pre-sloped drainage systems on taxiways and hangar bays since drainage areas are relatively small.

Municipal airports are a little bigger.  The aircrafts using the runways may include some light commercial crafts. Hangar doors will still use 4” wide trench drain, but these require reinforcement.  Along the taxiways, 8” and 12” wide pre-sloped drains with Class D and E grating prevent standing water.

International airports deal with big equipment and acres of concrete surfaces that need to be drained quickly in the event of a storm.  Trench drain systems generally have Class E or F load ratings and grates with 2-point lock down systems.  Trench drains designed for large flow capacities use grates with a high percentage of open area along with wider trench dimensions; it is not uncommon to see 12 inch wide trenches that reach 3-to-4 feet deep.
