An airport is a defined area on land or water that is used to land and take off aircraft, transport passengers, load and unload goods, and move transportation equipment. The airport is equipped with aviation safety and security facilities, as well as main and supporting facilities. The airport drainage system is one of the airport’s safety and security features.
Airports serve the following functions:
- The entry and exit of economic activities to achieve equitable development, economic growth, and stability, as well as the alignment of national and regional development.
- Because it serves as a hub for several networks and flight routes, it is referred to as an air transportation network node.
- Transfer point for air transportation to other modes of transportation and vice versa.
- Encouragement and support for the industrial, trade, tourism, and other development sectors
- Activating the isolation zone
What is the importance of the airport’s drainage system?
An airport’s drainage system is similar to that of a highway. The airport has the characteristics of a large paved area with a relatively flat gradient. Because the airport area requires rapid water absorption, an integrated drainage system is required. To avoid puddles, water on the surface must immediately flow into the drains. For the sake of flight safety, runways, taxiways, and aprons must be free of stagnant water.
A well-designed drainage system is essential for operational safety as well as the efficiency and durability of asphalt roads. Inadequate drainage can lead to flooding, endangering air traffic, erosion, saturation, and the weakening of asphalt road foundations.
What is the purpose of the airport drainage system?
A drainage system exists to prevent hazards, property damage, losses, and other loads caused by standing water.
Functions of the Airport Drainage System:
- Removing puddles from the airport area
- Controlling excessive rainwater accumulation
- Controlling erosion
Airport Drainage Castings
One aspect that contributes to a good drainage system is the use of drainage components. The drainage component serves as a drain cover, transporting water from the surface to the sewer. Manhole covers and gratings are common drainage components found in airport areas.
Because they are made of cast metal, airport drainage components are also known as airport castings. Ductile iron is the type of cast metal used. Ductile iron is strong and difficult to break, making it ideal for making airport drainage components.
Airport Manhole Covers
Manhole covers are typically used in the aircraft parking area (apron). Manhole covers are used to cover up access holes in closed drainage channels.
Airport Gratings
While gratings are typically used in the area between the apron and the taxiway. The purpose of gratings is to close open drainage channels. Gratings should be installed in a row along the drainage channel.
