Innovative Decentralized and low cost treatment systems for Optimal Urban wastewater Management. Reuse of treated wastewater is increasingly seen as one of the solutions to tackle the water scarcity problem and to limit the pollution load to surface water. Yet, using reclaimed water for non-potable purposes and particularly to irrigate food crops presents an exposure pathway for antibiotics and antibiotic resistant bacteria and genes (ARB&G) to enter the human food chain. Wastewater reuse is currently of particular concern as potential source of selective pressure that elevates the levels of antibiotic resistance in native bacteria. More
