Controlling Water Supply Quality: Case Study Of Souk Ahras City In Algeria

Résumé: The treated drinking water produced by water treatment plants and transported via the water supply network to users is never sterile. This is why we refer to the disinfection rather than the sterilization of public water supplies. Microorganisms have the opportunity to contaminate the water at various points in the network, such as at reservoirs, where the water is in contact with the air and poorly protected openings can allow contamination from dust or insects. Network interventions (repairs, connections), leaks (in the case of depression), and accidents such as backfows or breaks can also result in the introduction of microorganisms into the network. To facilitate the monitoring and control of waterborne diseases, a sampling-based study was carried out during the spring and summer periods of 2017 and 2018 in Faubourg, Souk Ahras City, Algeria. A precise inventory of the physicochemical and bacteriological quality of the water in the network in Faubourg was established for diferent areas of this urban neighborhood. The results show that the development of a fast strategy is inevitable.
