Birco 300AS

The function of the Birco linear drainage system is to intercept, store and transport surface water. For normal surface water drainage there are six different Birco systems.

Birco 300AS comprises a range of channels, gratings and covers together with complementary in-line side outlet and junction outfalls. This system is ideally suited to perform with large surface discharges such as aircraft pavements and industrial hardstandings.
