This work on the impact of pollution of Lake Kivu waters on its biodiversity by considering the section of the Independence Square - Kazingo Bukavu led us to make a finding on the decrease in the quantity and quality of fish, as a consequence direct pollution of Lake waters with negative impact on its biodiversity. This pollution of Lake Kivu by streams and rivers results from industry and household waste. Industrial waste is channeled there and households use streams and rivers as a dump. The waters of the Kawa River that cross the entire Greater Kadutu Commune from the West to the East are highly polluted and are of no use without serious treatment beforehand. The most polluted points are downstream of industrial wastewater discharges and all along rivers and streams where all forms of spilled waste end up in Lake Kivu. This water pollution causes olfactory nuisance on a large part of the population who complains of water-related diseases such as typhoid fever, cholera, etc. People settled in the bed of rivers and streams are well aware of floods by the waters that return to their natural bed in the rainy season. These floods are indeed true sources of contaminations because of their high level of pollution. The creation of an Integrated Watershed Management Committee and the construction of a waste treatment plant bringing together all the watershed stakeholders around a table for information and awareness raising for change in behavior, could reduce the flow of waste dumped in Lake Kivu.
Author Keywords: Pollution, incidence, biodiversity, waters, lake Kivu.

Abstract: (french)
Ce travail sur l’incidence de la pollution des eaux du Lac Kivu sur sa biodiversité en considérant le tronçon place de l’Indépendance – Kazingo à Bukavu nous a amené à faire un constat sur la diminution de la quantité et qualité des poissons, comme conséquence directe de la pollution des eaux du Lac avec impact négatif sur sa biodiversité. Cette pollution du Lac Kivu par les cours d'eau et les rivières résulte des industries et des rejets ménagers. Les déchets industriels y sont canalisés et les ménages utilisent les cours d’eau et rivières comme leur dépotoir. Les eaux de la rivière Kawa qui traversent toute la Grande Commune de Kadutu de l’Ouest vers l’Est sont fortement polluées et ne sont d’aucune utilité sans un traitement sérieux au préalable. Les points les plus pollués se situent en aval des rejets des eaux usées industrielles et tout le long des cours d’eau et rivière où toutes formes des déchets déversés finissent dans le Lac Kivu. Cette pollution des eaux cause des nuisances olfactives sur une bonne partie de la population qui se plaigne des maladies liées à l'eau notamment la fièvre typhoïde, le choléra, etc. Les populations installées dans le lit des cours d'eau et rivières connaissent bien des inondations par les eaux qui retrouvent leur lit naturel en saison des pluies. Ces inondations sont bel et bien des véritables sources des contaminations à cause de leur niveau élevé de pollution. La mise sur pied d'un Comité de Gestion Intégrée du bassin versant et la construction d’une usine de traitement des déchets mettant ensemble tous les acteurs du bassin versant autour d'une table en vue de l'information et de la sensibilisation pour le changement de comportement, pourrait réduire le flux de déchets déversés dans le Lac Kivu.
