ABSTRACT:
An irrigation or drainage system is provided comprising one or more conduits having radially positioned spaced apertures in the walls thereof, the system being otherwise closed except for an inlet/outlet aperture. The exterior of the conduits is covered by a snugly fitting fine mesh fabric sheath which covers all of the radial apertures, the interstices in the mesh of the fabric being very small and uniformly distributed such that fluid under slight to moderate pressure will flow through said sheath at least partially as the result of capillary action, and fluid distribution will be uniform throughout the length of the fabric sheath and about the periphery thereof.
