Summary:The wastewater treatment plant (WWTP) of the city of Kenitra treats urban wastewater, this said treatment produces significant quantities of dehydrated sludge which are then placed in the public dump. The valorization of the dehydrated sludge of the WWTP-Kenitra became a priority, seen the enormous quantities produced of their complex and heterogeneous composition. Objective: It is in this present work which aims at following the fate of the dehydrated sludge of the WWTP-Kenitra after their dehydration as well as their characterization by the analysis of the heavy metals in order to study the possibility of their valorization with one of the dies answering the protection of the environment. Results: The results of the analyses of the composition of the dehydrated sludge in Metallic Traces Element is in conformity with the standards AFNOR and the directive 86/278/CEE of the European Commission and does not reflect any danger in their use for the agriculture. Conclusion: The valorization of the sludge of the WWTP of the city of Kenitra is encouraged.
