Published on

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. 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

  34. 34. Trial results of comparison of irrigation by drip and by Buried Diffusers in the greenhouse of farmer field in Region Maatoug (Desert of south of Tunisia)  The Buried Diffuser produces 3 to 5 times more yield than the drip method. www.chahtech.com 34
  35. 35. www.chahtech.com 35
  36. 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. 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. 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
  51. 51. Drought 2002 in Center Tunisia hills lakes are empty and the irrigated agriculture based on the water of these lakes is in crisis: no production of vegetables and fruits.

Anticipated Irrigation Instead of irrigation during the hot or the dry season, the irrigation using Buried Diffusers is done during the autumn and winter or during the rainy season. The amount of water of the Anticipated Irrigation should cover the total need of the crop during the hot or dry season (spring and summer). This water amount is stored in the deep soil layers will be used by the deep or sub surface roots systems of the crops. www.chahtech.com 55
