The water of the river N’djili is used for several facts.

Yet several human activities susceptible to damage the quality of the water of this river are identified in its perimeters very brought closer. The danger is that in case of pollution of the river N’djili, several score of thousands of Kinshasa’s population should be exposed directly to water illnesses with risk of the epidemiological propagation, while the REGIDESO will be obliging to use big quantities of reagents to succeed in purifying this water polluted without forgetting the risk of resistance of some badly known pollutants. It will be able to be obliged however to resort to a lot of more refined techniques and expensive. A resource of as big importance had to absolutely be protected while the activities capable to harm to its good working should be regulated restricted either.

Abstract: (french)
L’eau de la rivière N’djili est utilisée pour plusieurs faits. En effet, faute de la desserte en eau potable dans plusieurs quartiers de la ville de Kinshasa, plusieurs riverains utilisent l’eau de cette rivière (brute) comme eau de baignade, de cuisson, de lavage de linges, de boisson, d’arrosage des jardins et lavage des produits de jardinage (légumes et tubercules), etc. Il y a lieu de souligner que le plus grand utilisateur de l’eau de la rivière N’djili c’est la REGIDESO qui soutire chaque jour un volume nominal équivalent à ±550.000 m3 d’eau brute en vue de l’épurer pour desservir au moins ¾ de la population kinoise en eau potable. Pourtant plusieurs activités anthropiques susceptibles de détériorer la qualité de l’eau de cette rivière sont identifiées dans ses périmètres très rapprochés. Le danger c’est qu’en cas de pollution de la rivière N’djili, plusieurs dizaines de milliers de la population kinoise sont exposées directement à des maladies hydriques avec risque de la propagation épidémiologique, tandis que la REGIDESO se trouvera obliger d’utiliser des grandes quantités de réactifs pour parvenir à épurer cette eau polluée sans oublier le risque de résistance de certains polluants mal connus. Elle pourra cependant être obligée de recourir à des techniques beaucoup plus affinées et couteuses. Une ressource d’aussi grande importance devait absolument être protégée tandis que les activités pouvant nuire à son bon fonctionnement devraient être réglementées ou restreintes.
