In countries with limited water resources, the reuse of wastewater appears to be a necessity.
To produce quality treated water without risk to health (and thus allow its reuse), a treatment plant must be equipped with a so-called “tertiary” treatment, which complements the secondary biological treatment (the latter allowing only a discharge to the natural environment).
The tertiary treatment technology often applied is a preliminary filtration for the reduction of suspended matter (MES), followed by disinfection with ultraviolet rays, aimed at the elimination of pathogenic germs.
If the technology is perfectly mastered, it is at the level of the legislative framework that efforts must often be made by governments, to determine the rules for the reuse of treated water, and the sectors of activity that will benefit from it ( industry and agriculture in particular).
In Morocco, the AGIRE (Support to Integrated Water Resources Management) program contributes to the kingdom’s efforts to reach the target of 325 million cubic meters of water reused by 2030, reaffirmed as part of the Paris agreement on climate change.
In Tiznit, for example, farmers will soon be able to benefit from this purified waste water.
