Treated wastewater reuse (TWWR) helps to meet growing water demands, reduces degradation of the quality of conventional water resources and contributes to soil fertilization. But, TWWR requires irrigation methods that minimize risks for health and the environment. At the international level, guidelines and recommendations have been developed based on health risk assessment processes, which form the background for most of the proposed guidelines on TWWR in other countries (Aquarec project, 2006; EPHC/NRMMC/AHMC, 2006; EPA, 2012). France has recently adopted regulations concerning the treated wastewater reuse for sprinkler irrigation, including the use of water from urban wastewater treatment plants for field crops or green spaces irrigation (ANSES, 2012; NOR-AFSP1410752A, 2014; NOR-TREL1803081A, 2018). However, there is still lack of knowledge about dispersion of inhaling pathogens such enteric viruses or toxic contaminants by sprinkler irrigation.
