Since water is essential to sustain life, and when supplied as drinking water to consumers, a satisfactoryrnquality must be maintained so that, provision of water, sanitation and good hygiene services are vital forrnthe protection and development of human resources. Though ground water is much better than surfacernwater in terms of biological quality, lack of source protection and inefficient treatment, wasternmanagement and sewerage system problem, poorly designed pit latrines and poor hygienic practice at thernhouseholds affect the quality of the water. Therefore, assessment of physico-chemical and microbiologicalrnquality of drinking water from sources to house hold in selected communities of Akaki-kaliti sub city,rnAddis Ababa City Administration were conducted.rnThis study was conducted from September 2006 to January 2007. A survey of 82 triplicate water samplernand sanitary surveys were conducted in 7 raw water sources, 5 chlorinated and non-chlorinated waterrnpoints, 35 pipe water and 35 randomly selected householdsâ€™ storage water containers. The water samplesrnwere examined for TTC and FS using membrane filtration method.rnAll raw water samples were positive for TTC and FS. High bacteriological load were found in BH8 (52.5rncfu/100ml) for FS and FSNC (29 cfu/100ml) for TTC. TTC and FS concentrations detected were 12.3 andrn11.6 cfu/100ml, respectively for bore hole EP4. For un-treated water sources the (KGW, EP5) TTC countsrnwere higher (>15 cfu per 100). Similarly, the FS count for KGW (>15 cfu per 100 ml) was higher thanrnEP5 (2 CFU/100ml). The health risk matrix assessment indicated that both the EP5 and KGW for TTCrnwere within high risk score while FS risk to health classification EP5 and KGW lie on medium and highrnrisk score, respectively.rnTemperature at all three disinfection points were above permissible limit of 15 oC. Turbidity at CTR andrnFSC met the acceptable level of WHO and National standard limit of potability < 5 FAU. TDR was abovernthe recommended limit. The pH values at all the three points were within the recommended limit (6.5 -rn8.5). The free chlorine residual were 0.67, 0.6, 0.68 mg/l at CTR, TDR and FSC respectively which arernless than the average value of the recommended limit of WHO (>0.8mg/l). Even if disinfected waterrnsources (CTR, TDR, FSC) were better than non disinfected water sources (EP5, KGW), all sample sourcesrnwere contaminated with TTC and FS having cfu >1 per 100ml and this were found out to be above WHOrnand National standards (cfu/100ml=0).rnOnly 1(2.9%) of pipe water samples was
