摘要：
An irrigation pipe (12) with holes is provided. The pipe is, at least in the area of each hole, multilayered. At least top (152a) and bottom (152b) layers of the pipe (12) are made of a water-repellant material, and an inner layer (154) of the pipe (12) is made of a porous material. The hole is defined by a cut surface of the pipe wall. The cut surface comprises a seal, which covers at least the inner layer (154). Each layer (152a, 152b, 154) may be bonded to adjacent layers.
