A survey on the parasitological and bacteriological management was conducted in two villages in southeastern Senegal. The objective of this study was to evaluate the water management modalities in the two villages with ethnic differences and possibly detect factors that could cause waterborne diseases. A questionnaire on water management methods was submitted to one hundred one women drawn in the villages of Dielmo and Ndiop. Samples of well water and water stored in canaries were subjected to both parasitological and bacteriological analysis. In both villages, there was a difference in water management with respect to household configuration (monogamous, polygamous). The containers used for the drawing and storage of water were the same in their two villages. No helminth eggs were found in the drinking water, but bacterial germs, especially faecal coliforms (an indicator of human contamination) and Enterocoques (an indicator of animal contamination). These waters do not comply with WHO standards. So it is important to disinfect them before consumption although no cases of gastroenteritis have been reported.
