Qualified disposal of sediments from drainage systems<\/strong><\/h1>\n

Stormwater treatment facilities are an essential part of the drainage systems of trunk roads. The surface water accumulating on the carriageways and the associated ancillary facilities is collected and fed into the facilities. Here, particle-bound pollutants sediment along with the suspended matter. The sludge from the sedimentation plants has a high water content, which may preclude direct delivery to a landfill. Prior to disposal, it must be checked whether the intended disposal route requires sludge dewatering and which process is intended for this pre-treatment.<\/p>\n

In order to maintain the functionality, the sedimentation areas and flow channels in the stormwater treatment plants must be cleared regularly in accordance with the generally recognised rules of technology and the water law approval notices. The sediments in the settling area and in the flow channels are mixtures of mineral components that contain impurities typical of roads. Prior to clearing, the sediments in the sedimentation basins must therefore be sampled and subjected to laboratory analysis.<\/p>\n

Depending on the results of the investigation, the sediments from drainage systems are to be assigned to one of the two waste types:<\/p>\n
