Wastewater reuse in agriculture sector: resources management and adaptation in the context of climate change: case study of the Beni Mellal-Khenifra region, Morocco

Recent climate change effects worsened water scarcity in Morocco and forced the country to seek alternative water resources such as domestic and industrial wastewater. In this context, we assessed the treatment efficiency of wastewater treatment plants (WWTP) of the BeniMellal-Khenifra region based...

Summary:Recent climate change effects worsened water scarcity in Morocco and forced the country to seek alternative water resources such as domestic and industrial wastewater. In this context, we assessed the treatment efficiency of wastewater treatment plants (WWTP) of the BeniMellal-Khenifra region based on physicochemical and biological parameters. Vegetation cover evolution near WWTPs was also analysed using satellite images (Landsat TM and OLI). Six WWTP were evaluated based on treated water quality and a survey of nearby farmers and residents. Results showed treated wastewater is in line with Moroccan standards, and can be reused for irrigation and aquaculture without harmful effects. The survey pointed to the Boujaad WWTP as a model in the region. The vegetation cover evolution before and after WWTP existence showed an important improvement of cultivated lands. As a conclusion, wastewater reuse will allow the BeniMellal-Khenifra region to secure agricultural irrigation to safeguard freshwater quantities and quality despite climate change.
