Characterisation of Treated Wastewater of M’Zab Valley for Reuse in Irrigation (Southern Algeria)

Treated wastewater from the M'Zab Valley, Algeria, shows limited suitability for irrigation despite meeting some national and international standards. The study, conducted over two years (2013-2015), analyzed physical-chemical and bacteriological parameters to assess the effectiveness of a natural lagoon treatment system. While biological treatment reduced pollution, the water was deemed poor quality, only viable for salt-tolerant crops on well-drained soils with additional treatment. This research highlights the challenges of reusing treated wastewater in arid regions like the Sahara, where water scarcity is a critical issue.
