ABSTRACT:
The irrigation apparatus includes a quick-connect, self-piercing drip emitter insertable in a plastic pipe to effect a controlled, localized trickle of irrigating water. The apparatus is usable either above the surface of the ground or below the surface and may include a protective wrap to keep dirt from clogging the emitter and to spread the flow of irrigating water over a larger area.
