- The pollution of the environment is a major global problem in most developing countries. It leads to serious problems which are sometimes irreversible. Factors influencing the pollution of the environment in developing countries include the demographic growth; economic development; industrialization; etc. The wastes from these human activities are not treated by either formal or informal authorities. Instead, they are discharged in the environment, where they may pollute water; soil and air. Such pollution can cause health problem in human and biodiversity via infection with pathogen microbes; accumulation of heavy metals; eutrophication in aquatic ecosystems; etc.

- In the DRCongo and particularly in Bukavu Town (Ibanda District), most of domestic waste is not treated by any organization. It is, however, discharged into rivers; grounds; along the roads and streets; etc and may lead to environmental pollution. The pollution with domestic waste can increase the rate of mortality and morbidity in human and the biodiversity in natural ecosystems.

- The present research has been motivated of how citizen in Bukavu Town and particularly in Ibanda District hold domestic waste, when the later may cause health risk problem in beings.

- It aims to evaluate the knowledge level of Bukavu Citizens on domestic waste management. To achieve this goal, a questionnaire has been addressed to families in Ibanda District from December 2010 to April 2011. The population in this district has been grouped in families from which the sample was taken guided by the estimated table of Depelteau (2001).

- The data obtained from the enquiry have been gathered by the software “ EPI-INFO” and thereafter analyzed by the statistic test of “Chi-square”.

- The result to which I arrived in this research revealed that the families in Ibanda District dispose garbage can (81.9%) made of sacs (62.2%) in which solid waste are stored daily. The garbage can are positioned nearby the home families (68.7%) and are empty a day perweek (64%) in the gardens (29.4%); the rivers (6%); canals (27.7%); etc.

- The landfills observed in Ibanda are located along the roads; the streets; at the margin of stadium; etc. where the waste are either incinerated (56.4%) or decomposed (23.4%). The effluents from the landfills may reach water bodies through runoff during heavy rains.

- Liquid domestic waste consists of water using to wash cloves and utensils and toilet wastewater. In fact, the toilets in Ibanda are made of septic hole which wastewater can infiltrate aquifer water. Families, which do not have such facilities, living along the canal; the river and Kivu Lake, simply release fecal matter into water.

- The results of the enquiry leading in Ibanda showed that the citizens do not have a best level knowledge in domestic waste management. This gap should expose citizens and the biodiversity to several health risk problems through pathogen infections, heavy metals and others pollutants linked to domestic waste. The results of this research should awareness urban authorities in Bukavu to sensitize citizens in waste management in order to reduce the environmental pollution.
