Feasibility of Water Reuse for Agriculture—Case Study of Ain Temouchent (Algeria)

This work seeks to study the feasibility of reusing the treated wastewater for agricultural purposes. The area under investigation is Ain Temouchent located in Northwestern Algeria. Climate studies have shown that climate change through the drought period that occurred in the past decades has affected the whole country. This has been characterized by a negative impact on available water resources as well as on the agricultural productivity. It is therefore imperative to rationalize the use of conventional water resources. This research was conducted in the WWTP of Ain Temouchent. Analyses were carried out on the physico-chemical and microbiological parameters of the treated wastewater. The water quality has been compared with the World Health Organization (WHO), Food and Agriculture Organization (FAO) and Algerian standards of water quality for irrigation. Following the interpretation of the results, the treated wastewater could be used for the irrigation of fruit-bearing trees, especially for olive tree.
