This research tries to as sess household water supply and factors affectingrnconsumption levels in Mekelle town. It is with the main objective of assessingrnthe water supply problems and major factors that affect household per capitarnwater consumption in the town. To achieve this, relevant data were gatheredrnfrom both primary and secondary sources. The major primary instrument ofrndata for the study was household questionnaire survey. A sample of 200rnhouseholds was selected using systematic random sampling method fromrnfour "Tabias' and responses of the questionnaire survey were entered intornSPSS and STATA Software for analysis.rnAs found out, mean daily p er capita water consumption of sample householdsrnwith private connection (group 1), households with out private connectionrn(group 2), and households with private connection and water vendors (grouprn3) is 49.5 l/c/ d, 11.9 l/c/d and 83.9 l/c/d respectively. Daily per capitarnwater consumption of those households who do not have their own privaternconnection is 11.9 liters. This is lower than the amount specified by Ministryrnof Water Resource (1996) which was 20 liters of water p er person p er dayrnand far lower than the WHO standard (45 1/ c/ d).rnThe result of regression analysis indicated that average income of householdrnheads, household size, presence of meter connection, and flu sh toilet arernstatistically s ignificant to explain the variation in daily per capita waterrnconsumption among households in the town.rnHence, income, presence of meter connection and flush toilet are positivelyrnrelated to mean daily water consumption p er capita (Y). On the other hand,rnhousehold size is negatively related to mean daily water consumption p errncapita (Y). Therefore for appropriate water supply projection, a detail study onrnthe physical and socio-economic factors affecting per capita waterrnconsumption are desirable.rnKey words: Supply, Phys ical, Socio-economic, Household, Per capita,rnConsumption, Daily
