| Résumé : |
The present report is an overview of water availability and distribution, water
consumption, and wastewater treatment trends in Saida. Aspects of current practices of municipal wastewater treatment are discussed in addition to current standards, both for disposal into surface water, and impacts in terms of water savings, socio-economical and environmental benefits of wastewater treatment and reuse. The current study has been carried out to support the use wastewater reuse in agriculture irrigation in farm workers. The main health outcomes to be considered were gastro-intestinal infections including intestinal parasite infections (intestinal nematodes and protozoa), specific bacterial infections (e.g. cholera, typhoid), specific viral infections (enteroviruses, hepatitis A) and symptomatic diarrhoeal disease However, our project is not accomplished yet because of corona virus and no development of hypothesis was stated in our work. So we ask you to accept our apologies. |
