The problem of water supply from the public distribution network is still very acute in many cities in developing countries. This work shows the problem of sustainability of water storage tanks made of concrete, in an aggressive environment but also especially the physicochemical quality of water stored in. The approach chosen is based first of all on the physicochemical analysis of the water stored in these tanks.

The problem of water supply from the public distribution network is still very acute in many cities in developing countries. This work shows the problem of sustainability of water storage tanks made of concrete, in an aggressive environment but also especially the physicochemical quality of water stored in. The approach chosen is based first of all on the physicochemical analysis of the water stored in these tanks. The reliability of tanks, which reflected in their impermeability overlooked external environment, has a direct impact on the quality of stored water and therefore the use that is made daily. Some samples of stored water, about 42.10% poses a public health problem. These results have clearly demonstrated the porous nature of the concrete chosen as the base material used for the construction of said tanks. Thus, anthropogenic pollution is evoked, which is confirmed by the high levels of physicochemical parameters measured in samples RE01, RE02, RE03, RE04, RE04, RE05, RE10, RE11 and RE12. In addition, 57.9% of these stored waters have low mineralization. These are acceptable as drinking water (RE06, RE07, RE08, RE09, RE13, RE14, RE15, RE16, RE17, RE18 and RE19).
