Abstract

This study was initiated to better understand the varying physical and chemical parameters of the water in order to ensure its effective treatment. With rainfall ranging from 11.6 to 24.4 mm in 2018 and from 54 to 114 mm in 2023, the Yamoussoukro district receives ample rainfall. Average physical parameters such as temperature and pH are less affected by the dry and rainy seasons. In contrast to these two physical values, turbidity is very high during the dry season, with a maximum value of (7.83 ± 0.40) NTU, which accounts for the reddish color of the water. As for chemical parameters specifically COD and nitrate, the highest concentrations were observed during the rainiest months: 82.18 ± 0.19 mg/L and 103.23 ± 1.05 mg/L for COD and nitrate, respectively. Lake water with conductivity outside the (200–1,000) range specified by the WHO during the dry season has a higher bacterial load during the rainy season. Overall, the filter becomes saturated more quickly during the dry season than during the rainy season, resulting in a volume of 18 m³ and 22 m³ during the dry and rainy seasons, respectively.
