The conduit comprises at least two compartments having specific relative dimensions and disposed in fluid communication with one another wherein the configuration and disposition of the two compartments are defined by the configuration of the single wall portion which is formed from the single piece of extruded material. Dispersion means in the form of a strip of elongated liquid permeable material is mounted within one of the compartments and configured to extend outwardly to the exterior of the conduit whereby liquid is dispersed through the two compartments to the exterior of the conduit through the liquid permeable dispersion element by a capillary-type action.
