The aim of this study was to assess the impact of knowledge and hygienic practices of the community on bacteriological quality of drinking water at the source and point of use. community based cross-sectional study was conducted using questionnaire, inspection check list to observe the condition of water sources, and bacteriological water quality examination of sources and household containers. The study was conducted during February-May 2011 in rural Communitie Council. Three hundred eighty four households were selected using systematic random sampling method to assess the knowledge and hygienic practices of the community and gathered by health extension worker under strict supervisi supervisors. Bacteriological examination of six water sources systematically selected household containers was carried out by using Oxfam DelAgua water testing kit. Almost all of the water sources were subjected to contamin score. There is a significant variation between the bacteriological analysis of source water and household drinking water samples. Educational status was the only variables which was significant after adjustment of other socio demographic, Knowledge and practices variables. However other variables like: types of household containers, washing of containers before transferring, methods of water withdrawal, duration of stored water and cover of container during transportation and storage were significant in bivariate analysis but not in multivariate analysis. This may be due to confounding effects of different variables. high sanitary risk score were highly subjected to bacteriological con feacal coliform almost tripled at household level, because of poor household management INTRODUCTION Water is the essence of life and safe drinking water is a basic human right essential to all, and for sustainable development. It is known that water is our most precious resource, vital to our economy, our daily lives and to the health of our environment. Water and sanitation inadequacies hinder economic and social development, constitute a major impediment to poverty alleviation and inevitably lead to environmental degradation (WHO, 2004). A community ravaged by diarrheal diseases, dracunculiasis or schistosomiasis cannot look beyond its immediate problems towards social economic welfare. Safe water is the door way to health and health is the prerequisite for progress, social equity and human dignity (WHO, 2004).
