Considering the problems of water in the arid and semi arid regions in the world, our team (lead by senior scientific researchers specialized in water economy and efficient use of hydraulic resources), spent more than 25 years experimenting new techniques for irrigation and for the injection of retention water or natural sources water to be conserved in the deep soil. These researches results are an innovative technique which is called: The Buried Diffuser. This worldwide patented (PCT) invention was awarded multiple times.

  • 25. Important water saving Important Energy saving The water saving reaches 100% (0% evaporation), thus the irrigation frequency is considerably reduced. The pumping time is less important because of the reduction of needed irrigation water. In addition to that the energy saving is higher when the diffuser works with gravity. Less weeds pulling out, less irrigation frequency, less mulching actions, etc. Important reduction of fertilizers amounts Longer life for water distribution pipes Important reduction of Herbicides and pesticides All the network could be totally buried (20 cm below the topographic surface). No weeds for vegetable fields and trees plantations, this is a great contribution in the protection of the environment. Less degradation of fertilizers and less loss leaching. Fertilizers directly delivered to roots the by are the www.chahtech.com Important reduction of labour for the maintenance of soil 25

  • 35. www.chahtech.com 35
  • 36. Decreased water cost The water saving reaches 100% (0% evaporation), thus the irrigation frequency is considerably reduced. Healthier plants and better quality crops Soil and foliage are kept dry, reducing fungal diseases caused by surface or overhead irrigation. Eliminates fruit and vegetable spotting. Increased revenues from increased yields Crop productivity increasing 3 to 5 times more than when using the drip while reducing 2 times less the irrigation water. Decreased Labor cost Less irrigation tasks, easier fertilizer application, less weeds and diseases control… Decreased pesticides and herbicides amounts Reduction of water vapor inside the greenhouses No weeds in the irrigation by buried diffuser (for vegetable fields and trees plantations), this is a great contribution in the protection of the environment. This has a good impact by reducing the development of diseases. This low rate of water vapor inside the greenhouses, facilitates the movement of pollen and increase the rate of flowers producing fruits. www.chahtech.com 36

  • 49. During 2012 north of Tunisia got exceptional heavy rains. This generated catastrophic floods in many cities. The water flow of Medjerda River reached 300 cubic meters per second during 10 days (none stop). According to this flow 10 800 000 cubic meters have been evacuated to the Mediterranean Sea. This big amount of lost water, if injected in the deep soil layers of the plantations, is sufficient to maintain 540 000 adult olive trees in good production conditions during 3 successive dry years. www.chahtech.com 49
  • 50. The water flowing from the natural springs and not used during the autumn, winter and the beginning of spring is lost in the rivers. This lost water is estimated 23 328 m3 (from September till May) for a spring with a flow of 1 litter/second. If this volume is injected in the soil horizons, using buried diffusers, it is sufficient for the water needs of about 518 adult olive trees during 3 dry years (without any rain).   www.chahtech.com 50
