Airport Drainage

We can’t control the weather but proper drainage can facilitate the rapid removal of storm water from airport surfaces. Although some conditions are regional or seasonal, effective drainage prevents standing water which can ultimately delay and cancel flights.

Of course, the more surface area there is, the greater the amount of rainwater that is displaced. It all has to go somewhere that is practical and doesn’t create residual issues such as erosion or unplanned ponding areas.

County airports

County airports support small single and twin prop aircrafts. Pre-sloped 4” wide trench drain systems are found on taxiways and in front of the hangar doors. Loads are light (Class D) so these drains tend to use ductile or cast iron grates without reinforcement.

Municipal airports

Municipal airports are a little bigger with aircrafts that may include some light commercial crafts. Hangar doors will use 4” wide trench drain but will require reinforcement. Along the taxiways, 8” and 12” wide pre-sloped drains with Class D and E grating is recommended.

International airports

International airports deal with heavy equipment and acres of concrete surfaces that need to be drained quickly in the event of a storm. Drainage systems usually 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.

Trench Drain Systems offers exclusive product lines manufactured by TDS.

4 Considerations

Duck, Duck, Goose

Greenspace surrounding an airport with ponding issues needs to be properly drained to prevent areas that attract waterfowl and other wildlife. Taking this measure can prevent life threatening situations for aircrafts.

Locked & Secured

Avoid the potential for grates lifting to become flying projectiles from plan engines. Ensure that grates are securely placed and locked into position.

Legally Speaking

Location and design of drainage structures must comply with all airport surface requirements along with any related federal regulations.

Lay of the Land

When planning drainage systems for an airport you must first consider everything about the land including the slope, soil type, surrounding vegetation, and its permeability just to name a few.
