A flexible plastic pipe system is divided into sections either with a smooth surface or with a surface with transverse ribs. The sections with the smooth surface are provided with water drip-feed openings, water distributor labyrinths, and a surface layer of filter material which prevents the ingress of roots into the pipe. The outside dia. of the ribbed sections is greater than that of the sections with a smooth surface.
