Résumé
Recognizing wastewater as an additional water resource is mandatory to emphasize its beneficial opportunities, taking into consideration its potential risks. In this regard this study was divided into two trials : the first was carried out in the laboratory to investigate the impact of wastewater irrigation on the characteristics of three different soil textures and to elucidate the role that could be played by the soil in improving the treated effluent quality taking the chemical characteristics of the collected drained effluents as an indicator. The results showed that the finer the soil texture, the better the effluent quality. The second trial was a comparative study aimed to characterize the effect of irrigation with treated wastewater as compared to the irrigation with fresh water supplied with the optimum fertilizing levels, on maize growth and yield. The results favored much more irrigation with treated wastewater resulting in better quantitative and qualitative maize production.
