An underground irrigation or piping system for water or fertilizing adjacent soil. The irrigation or piping system may be a horizontal system or a vertical system. A pipe contains a first, larger cavity and a second smaller cavity. Water or other fluids may flow from the first cavity to the second cavity, through a transfer port or via a vortex created by a restriction within a coupling or other element of the system. As the fluid transfers from the first cavity to the second cavity, it obtains a higher pressure. Emitters, such as holes) in the pipe that communicate with the second opening allow the pressurized fluid to spray out of the pipe a predetermined distance. Nutrients, air, or other elements may be added in the system to further fertilize or encourage vegetation growth.
