Advantages
Thought-out in every detail
The ingress of seepage water can impair the water quality. GRAF tank and filter solutions are therefore sealed up to the top edge of the ground.
The complete package includes a basket filter for 100% water yield, making it ideal for small roof areas or downstream infiltration.
Includes telescopic cast-iron dome shaft withvehicle-loading cover. This enables installation e.g. under the courtyard driveway.
