Water is an essential material for the operation of factories. It is threatened by difficult circumstances and causes the disruption of different ecosystems especially in aquatic environments. The main problems characterizing water situation in Morocco today are linked to shortage’s aggravation through over-exploitation, and on the other hand to the degradation of the quality of water resources such as a lack of wastewater treatment. However, the depollution of these discharges requires several steps starting with the identification of different pollutants until their treatments. As a result, we carried out this first physicochemical characterization of the effluents of 5 industrial units along with the final collector at the exit of the industrial zone of Settat, and we discussed pollution load generated by each type of industry. The results show that these discharges were heavily loaded with organic matter and with high conductivity, compared with tolerances based on national and international standards for activities-related releases. Our approach aims to set up new methods on smart water management in Morocco based on techniques like regular monitoring and automatic sampling.
