The physicochemical, heavy metals and microbiological characteristics of the treated wastewater were carried out to determine if it could be used in the agricultural field as an alternative system for natural irrigation water, using as a case study the effluent of a wastewater treatment plant in Ain Defla, Algeria. The physicochemical results showed that the average values in the treated effluents ranged from 7.64 to 7.86 for the pH, from 1.86 to 1.97 mS/cm for the electrical conductivity, from 29.27 to 32.76 mg/ l for the COD, from 6.70mg/l at 8.87mg/l for BOD5, <0.03 mg/l for cadmium and <0.2 mg/l for nickel. All concentrations complied with national (Algerian executive decree) and international (WHO and FAO) standards. Furthermore, the average concentration of total coliforms in the treated wastewater also complied with national and international standards, suggesting that the treated water can be used as an alternative water resource for irrigation. The reuse of treated wastewater is both a political and socio-economic challenge. Moreover, this path can contribute to reducing water shortages by better preserving natural resources and contributing to the development of integrated water management systems.
