Abstract. In order to alleviate the water shortage observed in rural areas, Algeria has resorted to the use of treated wastewater from lagooning stations. The approach to the management of domestic wastewater is all the more interesting because it is part of an environmental context for the collection, treatment and recycling of treated water for agricultural purposes. This is lagooning as a purification process. The question is whether it meets environmental and health requirements. The present work aims to monitor and analyze the purification performance of six sewage treatment plants located in the region of Mascara (West Algeria) namely: Ghriss, Bouhannifia, Hacine, Mohammadia, Tizi and Froha, to examine the reliability of this wastewater treatment system in accordance with universal standards. We notice that purification performances are low and variable and remain dependent on the season for nitrates (NO3), ammonium (NH4+) and phosphorus.
