Abstract: Management of rainwater in industries is a challenge in many countries. This study, carried out at the Brasseries du Cameroun, at the plant of the Central Region, aimed to evaluate the management of rainwater within the plant. Thus, it was necessary to evaluate the current state of rainwater management according to the rainwater pollution prevention method proposed by the American Environmental Protection Agency in 2009, revised by Christopher Newport University in 2016 in the United. Furthermore, it was important to Characterize the pollutants in the surface water of the Aké River, which is directly located alongside the plant, and to identify the areas at stake in the plant. The range of activities carried out in the workshops, such as handling, the transfer of products from one workshop to another, washing (bottles, crates and tanks) and waste management, are all at risk of polluting rainwater. Solid waste constitutes 39% of the plant's potential pollutants, followed by fermentable products and waste (29%), chemicals (21%), metals (6%), bacteria (5%), biological products (3%), oils and fats (3%). These pollutants threaten the Aké tributary's water quality. This was observed on the results of: chemical dissolved oxygen demand COD reaching a maximum value of 860 mg/l at the brewery delivery station, suspended solids with a maximum value of 600 mg/l at the outlets of the stormwater drains at the wastewater treatment plant, and phosphate content with a value of 100mg/l at the conditioning, in the rainy season. This was observed on the results of: chemical demand for dissolved oxygen COD reaching a maximum value of 860 mg/l at the grain delivery unit, suspended solids with a maximum value of 600 mg/l at the outlets of the rainwater drains at the wastewater treatment plant, and phosphate content with a value of 100mg/l at the conditioning, in the rainy season. For this purpose, 50% of the plant' s areas are critical risk areas for stormwater management, 37.5% are catastrophic risk areas and 12.5% are tolerable risk areas. A corrective action plan worth 8,889,250 CFA francs has been proposed.
