Developed by Chahbani Technologies of Tunisia, the buried diffuser technology comes in three forms, for irrigating trees, vegetables and container plants.
In Tunisia, Algeria, Morocco, Qatar, United Arab Emirates, Greece, California, and France, it’s being used to irrigate olive, date palm, fig citrus, pistachio, almond and peach trees, grape vines and all kinds of vegetables, says the buried diffuser innovator, and founder of Chahbani Technologies, Dr Bellachheb Chahbani.
The buried diffuser typically consists of a 6 millimetre diameter flexible tube connected to a 16 to 20 millimetre diameter polyethylene high-density pipe. The whole diffuser set up is then buried in holes below the soil surface, next to the roots of trees and plants needing irrigation. Only the distribution water pipe that connects to the main reservoir and the flexible tube is visible on the ground.
