Evaluation de la qualité physico-chimique et bactériologique de l’eau du réseau de la région d’Alger : Cas de Kouba.

Abstract

This study aims to evaluate the physicochemical and bacteriological quality of water at the municipality of kouba,taking into consideration the problems related to the distribution of water namely the corrosion of pipes.to achieve this objective, water samples were taken at different water points such as: raw water, production plants as well as water storage places, The results obtained during this study indicate that the physicochemical quality of water on the samples analysed is in compliance with the standards, on the other hand ,at a microbiological level, the search and enumeration of bacteria revealed a rate of 22% of non-conformity from which these waters can only be consumed after a confirmation to affirm the results obtained.in terms of aggressiveness and corrosion of the materials in contact with water, the Langelier and Larson indication show that the water produced by El-Hamma station has corrosion and significant aggression, when water distributed by the SPIK and the field capturing Baraki,they a significant potential for scaling and corrosion.
