Evaluating the performance of irrigation systems is to identify management practices and systems that should be effectively implemented to improve the irrigation efficiency. This study was carried out at FIBIDP with the objectives of characterization of the project, evaluating its performance using selected performance efficiency indices and analyzing water productivity in terms of water applied and water consumed for future improvements. While conducting this study first, initial assessment and field observation, consultation with different stakeholders was made to visualize the study area. The scheme characterization and performance evaluation was made by comparing the functionality of the structures with the design and by measuring the canals discharge capacity, dimensions, length of flow, using selected performance indicators such as conveyance, application, storage and distribution uniformity efficiencies along with the water productivity in terms of water use efficiency respectively. Most of the structures found on main canal are in need of maintenance. The most problem of this project was not only timely completion but also frequent revision of design and shortage of budget that made the project under performance. Average conveyance efficiencies on lined and unlined canals were obtained as 95%, 51%, respectively. The application efficiencies were 56.0%, 68.4% and 72.9% in head, middle and tail end location of the scheme respectively. The water storage efficiencies For upstream 97.7%, For Middle stream 98.0% and For downstream 98.8%. Water productivities in terms of water applied for the three locations (head, middle and tail) test plots were obtained in the order of 12.1kg/m³, 18.1kg/m³ and 20.3kg/m³. Finally, the economic water use efficiency of test plots in terms of benefit-cost ratio were estimated and found as 2.66, 2.76 and 2.15 for head, middle and tail locations, respectively and found to be efficient. Hence, it could be concluded that productivity of the cropping system can be improved by minimizing water losses. Therefore, the major recommendations are forwarded for sustainable resource utilization. Timely design, construction, and timely maintenance of irrigation structures contributes for equity of water distribution among farmers at different locations and achieving the most plan of production. Preparation of extra drainage system is necessary for the scheme to avoid accumulation of excess water in the lower spots that leads to deep percolation loss.
