Abstract: Irrigation development has been identified as an important tool to stimulate economic growth and rural development, and is considered as a cornerstone of food security and poverty reduction in Ethiopia. While a lot of effort is being exerted towards irrigation development, little attempt is being made toward the sustainability of already constructed schemes. This study is an attempt to show whether already constructed scheme is sustainable or not, in the case of Nedhi Gelan Sedi SSI scheme in Eastern Oromia Region, Deder District, which was selected purposively. Therefore, the major concern of this study is to identify sustainability of the scheme from socio-cultural, environmental, physical, financial, institutional and community empowerment aspect .To realize these objectives, structured household survey questionnaires, semi-structured interviews, group discussions, field observations and literature were used. For household survey questionnaires a total of 88 sampled households were randomly selected. Physical stability , efficiency of the scheme, environmental protection, productivity, equity, collective action system resilience and relevance are those categories‟ that are selected to indicate practices under which we will feel confident that the system should continue to exist and to function, at least for time-span of 20-30 years. Categories are further expressed by around 36 indicators. By using the computed Yes or No response of the sampled household, rated scale of each category was calculated from rated scale of indicators. Finally, average value of all categories was taken to be the sustainability index of the scheme. The study indicates that, the approach of intervention was not participatory. The communities did not participate during study and construction period and no handing over of the project to the community. Elected committees were not representative of all villages and at this time water distribution, mass mobilization for maintenance and conflict resolutions were handled by traditional water leader Malaqa that are limited in their own village. Equality in water distribution is non-existence. Even if IFAD did the demonstration, the result was not satisfactory. Land scarcity is number one problem in the area. Siltation of head work and damage of column of flume is also a series issue that needs immediate solution. Watershed management must be practiced in the area. 92 percent of sampled households are not paid and willing to pay operation and maintenance costs, water fee costs and project recovery costs, which show weakness of financial viability of the project. As a result, the key findings of the study reveal that the sustainability index of the scheme was 1.31 which shows value approach to unsustainable condition, an outcome of lack of equitable resource distribution, which create lack of collective action towards the scheme sustainability issues, especially for operation and maintenances that harm stability of the physical capital by minimizing the efficiency of the scheme, coupled with low protective action of the environment, aggravate the problem and finally systems are no longer to deliver their benefit and the people are also no longer to devote necessary efforts to key activities and sustainability of the system become under question even for this generation. The supports from IFAD would have been more rewarding, if it is coupled with improvement of the condition of physical stability of the scheme with maintenance and establishment of representative WUA. Moreover, to improve the economic and environmental sustainability of small scale-irrigation schemes, institutional support (input supply, output marketing and credit services), training of farmers on improved crop and water management issues, regular supervision and monitoring of scheme activities are crucial.
