SITUATION DE LA REUTILISATION DES EAUX USEES EPUREES EN AGRICULTURE SAHARIENNE: CAS DE LA CUVETTE DE OUARGLA

Abstract

The reuse of treated wastewater can reduce the water deficit in the Saharan areas, especially in Ouargla. This research work in this area aims to study the situation of reuse of treated water in an agricultural perimeter of the basin of Ouargla. It is located north of the sewage treatment plant and supplied with water by it. Data collection was conducted through surveys and with the cooperation of farmers. The results obtained show that the operators are mostly adults. The rate of actual cultivated area reaches 45%. Most farms do not exceed one hectare. The family labor is the most used in the perimeter. The agriculture use the treated water for irrigation of the channel by mechanical pumping in the absence of conventional water wells. The reuse of treated wastewater in agriculture in Ouargla is encouraging but requires monitoring and further study to encourage the valorization of treated water in the entire agricultural sector of the basin of Ouargla
