Numerous studies have shown the variability of the physico-chemical and microbiological characteristics of meteorite waters collected and stored in recovery tanks. This variability can have negative impacts for users, physico-chemical and microbiological analyzes reflecting the quality of rainwater collected downstream from the roof and stored in a concrete tank were carried out. The chosen site is a rainwater tank whose use is not limited to laundry, some households use it for washing, for domestic uses in the kitchen, and even for drinking. The objective of this work is to assess the risks to which users are exposed when consuming collected and stored rainwater. The hydrogen potential analysis revealed an average content of 7.05. The turbidity value is less than 5NTU.The conductivity has an average value of 0,01005 µs/cm. The quantity of chloride ion is very varied for each sample analyzed, with an average of 227.47 mg/l in Cl-. The samples show considerable number of total coliforms.
