||Poor management of biomedical wastewater is a major threat for the environment and the public health. This
study aims to assess the activated sludge wastewater station of CNHU-HKM of Cotonou, the biggest hospital in
the country. Purposely, some parameters such as temperature, pH, dissolved oxygen, total dissolved solids,
biological oxygen demand, and chemical oxygen demand were measured at the entry and at the exit of the station.
Some microbiological parameters such as fecal coliforms and total coliforms have also been investigated. It came
out of our investigations that the wastewater treatment station is undersized compared to the current needs of
this hospital. Parameters measured at the exit are far beyond admitted World Health Organization standards.
Frequent dysfunctions are observed. Wastewater is frequently rejected inside the center without any prior
treatment. This results in the pollution of the ground as well as groundwater and constitutes a real threat for
