This study was undertaken in the Irhambi/Katana grouping. The purpose is to inventory sources for to determine the flow or theirs spatial distributions, to liberate the correlation between water quantity and household also presenting state source that is to say source hawk and not hawk also those dying up the grouping. The direct observation method and interview was used as a stopwatch and the global positioning system (GPS) for the geographic coordinates and the measurement of flow.
The results of this work demonstrate that geographically, sources are unevenly distributed across the grouping. From a quantities point of view most of sources in Irhambi/Katana produces little water. And according to altitude, the finding is that there are fewer sources upstream (high altitude) and more sources downstream, the shores of lakes –Kivu.
Water supply sources are very affected by seasonal variation of their flow during the year and this explains occasionally the use of water stream and Water Lake in spite of the latter condition that is polluted and therefore undesirable consumption.

Abstract
This study was undertaken in the Irhambi/Katana grouping. The purpose is to inventory sources for to determine the flow or theirs spatial distributions, to liberate the correlation between water quantity and household also presenting state source that is to say source hawk and not hawk also those dying up the grouping. The direct observation method and interview was used as a stopwatch and the global positioning system (GPS) for the geographic coordinates and the measurement of flow.
The results of this work demonstrate that geographically, sources are unevenly distributed across the grouping. From a quantities point of view most of sources in Irhambi/Katana produces little water. And according to altitude, the finding is that there are fewer sources upstream (high altitude) and more sources downstream, the shores of lakes –Kivu.
Water supply sources are very affected by seasonal variation of their flow during the year and this explains occasionally the use of water stream and Water Lake in spite of the latter condition that is polluted and therefore undesirable consumption.

Abstract: (french)
Cette étude a été effectuée dans le groupement d'Irhambi-Katana. L'objet est d'inventorier les sources d'eau tout en déterminant leur débit et/ou distribution spatiale, en dégageant la corrélation entre quantité d'eau et ménage aussi en présentant l'état de ces sources c'est-à-dire les sources aménages et/ou non aménages et aussi celles en voie de tarissement dans le dit groupement. La méthode d'observation directe et d'interview ont été utilisées ainsi qu'un chronomètre et un GPS nous ont aidés respectivement pour la mensuration du débit et la prise des coordonnées géographiques. Les résultats de ce travail démontrent que sur le plan géographique, les sources sont inégalement réparties sur l'ensemble du groupement. Du point de vue quantitatif, la majorité des sources d'Irhambi produisent peu d'eau. Et suivant l'altitude, le constat est qu'il y a moins de sources en amont (haute altitude) et plus de sources en aval, aux abords du lac Kivu. La fourniture d'eau de ces sources est très affectée par la variation saisonnière de leurs débits au cours de l'année ce qui explique des temps en temps le recours à des eaux des ruisseaux et du lac par la population malgré l'état de ces dernières qui sont polluées et par conséquent indésirables à la consommation.
Author Keywords: nappe aquifère, source, ménage, affleurement, débit.
