Adequate and sustainable water supply in rural areas of Machakel Woreda is very low. Effortsrnmade so far to improve the existing water supply situation have been threatened (vulnerable) byrnmultiple interlinked problems. Knowledge of the problems of rural water supply and communities’rnmanagement can help improving the problems of rural water supply in the future. Thus, thernobjective of this paper was to assess the Problems to Sustainability of Rural Water Supply andrnManagement Systems in Machakel Woreda, The researcher focuses on descriptive and crosssectionalrnsurvey research design where different data at points in time are collected to obtain thernnecessary information by applying both probability and non-probability to sampling designs tornidentify the sample kebeles and water supply schemes as well as the sample households. Householdrnsurveys, observation, key-informants interview and focus group discussion were used for primaryrndata collection. Documents review from different offices was used as a tool to collect valuablerninformation for secondary data. Three stage sampling method was used for primary data collection.rnFor the selection of kebele administration stratified sampling method was used based on agroclimaticrnzones. Two kebele administrations were selected from Woyna Dega and one from Degarnagro-climatic zones. Both Purposive sampling method and simple random sampling method wasrnemployed for village and households’ selection. Household survey was conducted in three selectedrnkebele administrations and 150 household heads were randomly drawn from the total 979 waterrnsupply user heads of households. Three focus group discussions were held with water committeernmembers, and kebele administration officials and 15 observations were conducted at different waterrnpoints. For data analysis a combination of quantitative and qualitative methods were employed. Thernmethod used for data analysis was simple description: like percentage, average, standard devotion,rntabulation and charts (figures). In conclusion various factors are interacting to maintain thernintended objectives of any water supply project. The utilization of water sources mainly depend onrntheir functionality, this in turn depend on the magnitude and types of community participation. Thernwhole purpose focused to sustain the continued use of water supply project, distances from thernwater pints, the involvement of community at all stage of water development, building of adequaternskill and considering the modest water services fees. It is also known that water office took thernresponsibility of to be handed over water supply schemes, unfortunately the water offices were notrnyet skill full and resources full to mange and maintain the existing schemes .Lack of tools, sparernpart, poor water committee’s effort, low senses of ownerships of rural water supply schemes by thernuser communities. The study revealed that weak institutional capacity, poor financial managementrnand weak linkage between water committees and Woreda Water Office are identified as the mainrnproblems in the study area. The evidence in the study area also indicates that poorly managedrnwater supply scheme has adversely affected access to potable water supply, especially where water supply schemes interruption was with high frequency. The policy implication of the study is strengthening of the institutional capacity (technical, financial human recourse and management capacity at Woreda and village (local) level Improving construction quality, strengths community participation and capacity building of the community in order to improve the rural water supply scheme management is recommended for the futures
