Airport drainage :-

An adequate drainage system for the removal of surface and subsurface water is vital for the safety of aircraft and for the long service life of the pavements. Improper drainage results in the formation of puddles on the pavement surface which can be hazardous to aircraft taking off and landing poor drainage can also results in the early deterioration of pavements.

Purpose of drainage :-

The functions of an airport drainage system are as follows;

• Intercepting and diversion of surface and ground water flow originating from lands adjacent to the airport.
• Removal of surface run off from the airport
• Removal of subsurface flow from the airport
