Amidst the ongoing global water crisis, the need to address wastewater treatment has become crucial in order to cater to the growing demands of populations worldwide. Algeria, recognizing this necessity, is actively striving to enhance its wastewater treatment sector, particularly for the reclamation of wastewater in both agricultural and industrial domains. This study focuses on evaluating the effectiveness of a wastewater treatment plant (WWTP) and its suitability for irrigation purposes at the Timgad WWTP located in Batna, northeastern Algeria. This WWTP plays a vital role in treating rural domestic sewage from the small town of Timgad, serving the dual purpose of safeguarding the Koudiat-El-Medouar dam against waterborne pollutants. By conducting comprehensive physicochemical analyses of the wastewater, the research aimed to assess the quality and efficiency of the treated wastewater in comparison with national and international water quality standards, particularly concerning its viability for irrigation. Drawing on data spanning from 2014 to 2023, the study demonstrated that all measured physicochemical parameters of the water consistently fell within the established national and FAO norms, with the exception of slightly elevated levels of orthophosphate. The study delved into the relationships of the analyzed water parameters. Notably, the findings indicated that the treated wastewater was effectively purified and suitable for irrigation purposes, although it remains unsuitable for human consumption. Consequently, it raises concerns about the potential risks to public health if the treated wastewater from the WWTP were to be mixed with the pristine water present in the dam reservoir, given the likelihood of contamination and its associated health implications. In light of these findings, it is recommended that further research and extensive studies be conducted specifically on the water of the Koudiat-El-Medouar dam. This recommendation is made not only to preserve the environment but also to safeguard the health of the local population.

摘要

Amidst the ongoing global water crisis, the need to address wastewater treatment has become crucial in order to cater to the growing demands of populations worldwide. Algeria, recognizing this necessity, is actively striving to enhance its wastewater treatment sector, particularly for the reclamation of wastewater in both agricultural and industrial domains. This study focuses on evaluating the effectiveness of a wastewater treatment plant (WWTP) and its suitability for irrigation purposes at the Timgad WWTP located in Batna, northeastern Algeria. This WWTP plays a vital role in treating rural domestic sewage from the small town of Timgad, serving the dual purpose of safeguarding the Koudiat-El-Medouar dam against waterborne pollutants. By conducting comprehensive physicochemical analyses of the wastewater, the research aimed to assess the quality and efficiency of the treated wastewater in comparison with national and international water quality standards, particularly concerning its viability for irrigation. Drawing on data spanning from 2014 to 2023, the study demonstrated that all measured physicochemical parameters of the water consistently fell within the established national and FAO norms, with the exception of slightly elevated levels of orthophosphate. The study delved into the relationships of the analyzed water parameters. Notably, the findings indicated that the treated wastewater was effectively purified and suitable for irrigation purposes, although it remains unsuitable for human consumption. Consequently, it raises concerns about the potential risks to public health if the treated wastewater from the WWTP were to be mixed with the pristine water present in the dam reservoir, given the likelihood of contamination and its associated health implications. In light of these findings, it is recommended that further research and extensive studies be conducted specifically on the water of the Koudiat-El-Medouar dam. This recommendation is made not only to preserve the environment but also to safeguard the health of the local population.
