The decreasing service function of the technical irrigation system should be supported by routine and periodical maintenance and rehabilitation which needs human resource and costs. Since limited resource is a problem to the government, an analysis of rehabilitation priority is required for 9 irrigation area in Kabupaten Purworejo. Rehabilitation priority analysis to the technical irrigation system taken in this study was carried out by assessing the irrigation water service function, water availability, and functional area. The service function assessment was based on the totally disturbed criteria, semi disturbed criteria, or not disturbed criteria. Results of the analysis showed that the first priority was for increasing the irrigation system status from semi technical to technical irrigation. The first priority was Tegalduren (small and semi technical irrigation) and the last was Krasak (small and technical irrigation). The next priority was large, medium and average irrigation system. Such condition implied that rehabilitation for small (technical) irrigation area was organized by the farmers themselves.
