<p>An irrigation system (30) for watering a substrate (S), comprising a pipe (31) having a longitudinal dimension. A hermetically closeable inlet portion (32) is connected to a water supply. A passageway (34) extends generally throughout the longitudinal dimension and is in fluid communication with the inlet portion (32) such that water can fill the passageway (34). Openings (35) are in fluid communication with the passageway (34) such that water in the passageway (34) can exit the pipe (31) through the openings (35). The openings (35) are distributed along the longitudinal dimension of the pipe (31), the pipe (31) being adapted to be at least partially buried in the substrate (S) with said longitudinal dimension being generally horizontal. Porous members (36) are secured to an outer periphery of the pipe (31) so as to each cover one of the openings (35) and so as to be in contact with the substrate (S) such that water flows out of the passageway (34) through the openings (35) and the porous member (36) and into the substrate (S) as a result of a capillary action of the substrate (S).</p> |
