Abstract (en)
[origin: EP1079026A2] The pipe has a concrete polymer wall (16). At least part of the wall is made of a filter material (14) that is permeable to liquids. The filter material is formed as gravel-like granules bonded together with a binder. Preferably, the wall has at least one radially arranged round hole (12), which is filled with a plug of the filter material. An Independent claim is included for a method to manufacture a drain pipeline.
