An inner pipe having a plurality of apertures on a top surface is connected to a pressurized water input source. The inner pipe is located within a slightly larger outer pipe and rests on a bottom inner surface of the outer pipe. The outer pipe is buried just below a plant root line. A series of longitudinal slots on a bottom portion of the outer pipe permits water flowing from the inner pipe to the outer pipe to trickle unimpeded into the surrounding soil.

An underground irrigation system comprising; an inner plastic cylindrical pipe impervious and inert to water connected to a pressurized water input source, the inner pipe having a plurality of apertures located on a top portion to permit flow of water from the interior to the exterior of the inner pipe, an outer cylindrical pipe slightly larger in interior diameter from an outer diameter of the inner pipe, the outer pipe being impervious to water and inert to soil chemicals enclosing the inner pipe, the inner pipe sealed at an end distal from the water input source to form a closed system, the outer pipe having a plurality of longitudinal slots located on a bottom portion with a bottom portion of the inner pipe resting on the bottom portion of the outer pipe, the outer pipe resting on an underground soil strata and being covered with soil, the slots permitting water to trickle from the outer pipe into the surrounding soil area which requires at least one pound per square inch pressure to be exerted on the water supply within the inner pipe.
