In this study, we are interested in evaluating the performance of a system for purifying wastewater by plants in an arid climate. The treated water is wastewater from domestic sources in the region of the old Ksar Temacine (Wilaya of Ouargla, South-East of Algeria). The results show good yields for organic and particulate pollution. Drawdown rate of approximately 97.49 % of Suspended Solids (SS), 90.85 % of Chemical Oxygen Demand (COD), have been achieved. The system effectively removes nitrate pollution 100 % of ammonium and phosphorus pollution moderately 62.28 % of orthophosphates. The system shows a very high removal of total coliforms (90 %).
