Abstract
Drinking water treatment and waste management have alarming dimensions in rural DR Congo, particularly in the Bengamisa region, and are currently experiencing continuous and permanent degradation.

However, water scarcity is characterized here by the abundance of dirty water whose use is a hindrance to the economic and social emergence of the population. The criteria for water scarcity in the Bengamisa region are lack of or poor access to drinking water, the preponderance of water-related diseases and above all the "doubt" that consumers have about the quality of water. of this resource.

Abstract: (french)
Le traitement de l’eau de boisson et la gestion de déchets présentent des dimensions alarmantes en milieu rural en RD Congo, particulièrement dans la région de Bengamisa, et connaissent actuellement une dégradation continue et permanente. Aussi, il existe une disparité entre les villes et au sein des villes et cela s’exprime en termes de qualité et quantité d’eau de consommation entre les zones bien équipées (zones régulières) et les zones faiblement équipées (zones irrégulières). Cependant, la pénurie d’eau est caractérisée ici par l’abondance de l’eau souillée dont l’utilisation constitue une entrave à l’émergence économique et sociale de la population. Les critères qui fondent la pénurie d’eau dans la région de Bengamisa sont l’absence ou faible accès à l’eau potable, la prépondérance des maladies liées à l’eau et surtout le “doute” qu’ont les consommateurs sur la qualité de cette ressource. D’une manière générale, l’objectif poursuivi par cette étude est d’évaluer l’impact des bouteilles en plastique dans le traitement de l’eau de boisson par rayonnement solaire, mais aussi sur la santé humaine. Pour atteindre les objectifs fixés, nous avons traité l’eau de consommation par la méthode SODIS, qui consiste à exposer sous soleil l’eau contenue dans la bouteille en plastique à base de PET pour sa purification. Ainsi, les paramètres physico-chimiques ci-après ont fait l’objet de nos analyses : le pH, M.O, couleur, turbidité, nitrate, nitrite, fer total et température ; et cela avant et après photo-épuration de l’eau. En effet, il ressort de nos investigations que la photo-épuration de l’eau ne modifie pas tellement les paramètres physico-chimiques de l’eau de boisson. De même, il est à noter que tous les plastiques ne sont pas anodins et qu’il faut se méfier en achetant non seulement de l’eau en bouteille mais également d’autres produits/aliments conditionnés avec du plastique. Mais, il est plutôt important de savoir quel type de plastique qu’on a à faire ; et que tous les codes, en général, sont mentionnés sur le fond des bouteilles, récipients, bouchons, etc. Pour ce faire, la bouteille en plastique à base de Polyéthylène téréphtalate (PET) est plus recommandée que les autres, à cause de sa performance en recette solaire. Il convient également de rappeler que, consommer de l’eau en bouteille nuit au portefeuille, à l’environnement, et « pourrait » nuire à la santé.
