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.
