  ABSTRACT: The objective of our work is to evaluate the purification performance of the Mechraa Belksiri (Gharb, Morocco) Wastewater Treatment Plant (WWTP) of natural lagoon type, and situate the treated wastewater with Moroccan and European standards. Sampling was carried out monthly during the year 2022. The wastewater from the city of Mechraa Belksiri is loaded with organic matter (BOD5/COD = 0.44 and SS/BOD5 = 1.39) and has a satisfactory biodegradability (COD/BOD5 = 2.29). The station has an excellent purifying power with a very satisfactory reduction in BOD5 (83.14%), COD (82.24%) and SS (74.03%). Even if the treated wastewater complies with the Moroccan standards in force with an average of BOD5 (62.75 mg of O2/l), COD (150.92 mg of O2/l), and SS (133. 25 mg/l), they don’t with European standards. Hence, an improvement is expected in the station system.
