El Oued’s Ghout are confronted with the phenomenon of the increase of water since about thirty years and which does not cease becoming extensive each year. The use of excessive water from aquifers of the Continental Intercalary, the Terminal Complex aquifer and the lack of a natural outlet for discharges of domestic water and industrial wastewater are the main causes of ecological imbalance. Among the problems that result from this lift, the disappearance of Ghouts and death by palms asphyxiation. Faced with this problem, various solutions have been implemented to stop this particular flood. It appears from this study that the achievement of a green belt around El Oued past two years is beginning to yield results; reducing the water level in the Ghouts is appreciable. With the completion of wastewater treatment plant (lagoon) and the use of treated wastewater in agriculture, the situation will be much more interesting in the coming years, except that the region of El Oued lose all Ghouts.
