Drainage systems for rainwater purification

Rainwater collected in drainage systems (e.g. from car parks) first needs to be filtered or purified before it can be either used or returned to the natural water cycle as groundwater. BG-Graspointner offers Austrian standard-certified drainage systems for line drainage and cleaning of pecipitation on car parks. Our drainage channels for rainwater are suitable as replacements for natural drainage systems – such as plants between parking spaces – and can be used on areas fully usable by traffic. The drainage systems for rainwater purification and treatment are highly efficient even in areas with a high water table and also require impressively little maintenance.
