Physico- Chemical And Bacteriological Quality Assessment Of Drinking Water From Source To Households Distribution Point In Debrezeit Town Ethiopia

In Ethiopia only 28% and 52% of the total population have access to sanitation and saferndrinking water respectively. As a result, 60-80% of the population suffers from waterbornernand water-related diseases. This is partly due to the lack of access to safe waterrndistribution systems. This thesis evaluates the physico-chemical and bacteriologicalrnquality of water from sources, disinfection point (DP), main distribution systemsrn(reservoir, MD) and private tap water samples of Debrezeit (Bishoftu) town, OromiarnRegional State, Ethiopia. The study was conducted from May 2008 to August 2008. Arntotal of 123 triplicate water samples were collected and analyzed from 5 wells, 1 DP, 6rnMD, and 29 tap water distribution systems. The temperature measurements of all waterrnsamples were between 19.9ºC and 25.5ºC and that of pH was between 6.9 and 7.7. Thernturbidity of water from the sampling sites showed significant variations ranging from 0-rn7.6NTU. Almost 30% of the turbidity measurements of the tap water samples werernhigher than that of the sources by a factor of 3NTU showing increment in turbidityrnrecords. However, only 6% of the water samples from the distribution systems werernfound to be greater than the maximum limits of the guide line value of
