Abstract


BACKGROUND: Lack of safe drinking water, basic sanitation, and hygienic practices are associated with high morbidity and mortality from excreta related diseases. The aims of this study were to determine the bacteriological and physico-chemical quality of drinking water and investigate the hygiene and sanitation practices of the consumers in Bahir Dar City, Ethiopia.
METHODS: A cross sectional prospective study was conducted in Bahir Dar City from October-December, 2009. Water samples were collected from 35 private taps and 35 household water containers for bacteriological analysis. The turbidity, pH, temperature and turbidity were measured immediately after collection. Finally, the hygiene-sanitation practices of the consumers were surveyed using interview.
RESULTS: Twenty seven (77.1%) of the household water samples had high total coliforms counts. Twenty (57.1%) household water samples and 9 (25.7%) of the tap water samples had no residual free chlorine. Sixteen (45.7%) household water samples had very high risk score to thermotolerant coliforms. Eight (22.9%) tap water samples had low risk score for total coliforms whereas 21(60%) tap water had very low risk score for thermotolerant coliforms. Twelve (34.3%) of the consumers collect water without contact with their hand and 9(25.7%) wash their hands with soap after visiting toilet.
CONCLUSION: Water supplies at tap and household water containers were contaminated with bacteria. Poor sanitation, low level of hygiene, uncontrolled treatment parameters are the causes for contamination. Control of physico-chemical parameters and promoting good hygiene and sanitation are recommended.
