<p>A simple system for underground irrigation has perforated tubing (2) threaded through a woven metal mesh, e.g. similar to chain link fencing, with the tubing secured by the corners of diamond pattern. The mesh forms a simple spacing system and helps to distribute the water in the spaces between the tubing. The mesh, fitted with tubing, is laid from a roll, and is covered by top soil layers, or can be used for above ground irrigation.</p> |
