Abstract: The study relates to the quality of raw water treated at the wastewater treatment station 'WTS' of Ouargla (Algeria). This study made it possible to highlight the importance of the physicochemical characteristics of wastewater within the WTS. The results we have obtained clearly show the effectiveness of such a system of urban wastewater treatment of a medium agglomeration. Pollution abatement achieves organic pollutants (COD, BOD₅, NO₃ and NO₂). Despite the efficient treatment of these waters remain of bad quality to very bad. They are rich in nitrates and phosphorus, which avoided the purchase of fertilisers, so they can be used for irrigating non-productive trees and palms according to FWO parameters.

Keywords: quality; characteristics; pollution; efficiency; urban wastewater; Ouargla; Algeria.
