It is now 3 years since SIREV began working on water management tools. In fact, irrigation technology has progressed significantly and it is becoming more and more difficult for the sites already equipped with the equipment and an efficient central control system, to improve their use of water with the introduction of only one single item of equipment. Furthermore, the problem of the availability of the water resource has become more and more critical, year after year, and it is now essential for all of the managers to be able to have at their disposal precise information about their consumption and actual use of irrigation water.
