Abstract



Many sections of Dschang town do not have pipe-borne water. For domestic purposes, about 25% of households cover distances of between 500 and 1000 meters to fetch water. The aim of this study is to see the possibility to bring the spring water closer to consumers. Analysis of the water is necessary before such a venture. The physicochemical analysis of spring waters consumed revealed their softness, their low level of mineralization and their aggressive character. Previous study indicated that Escherichia coli was present in
those springs with variations from one spring to another. Considering the physicochemical and biological aspects of springs, the study proposed that the water be treated with calcium carbonate in order to improve upon the total hardness, total alkalinity and to bring water to the calco-carbonic equilibrium. To disinfect the water, calcium hypochlorite was recommended as well as polyvinyl chloride for the mini distribution network.

Keywords: Langelier Index, calcium carbonate softness, remineralization, calco-carbonic equilibrium, network.
