Many irrigation schemes developed in Burundi indicate to perform below their potential. Major causes of poor performance are mainly due to the inequitable water distribution and mismanagement. This study aimed to evaluate the irrigation system using performance indicators and farmers’ knowledge. In this study, a float method was used for determining flow rate, the discharge and conveyance efficiency at the main secondary and tertiary canals. The task involved the determination of irrigation water allocation and distribution at main, secondary and tertiary canals. Based on the climatic data, the crop water requirement was determined and by discharge data, the conveyance efficiency, the adequacy, the efficiency, the dependability, the equity of water supply. We have also evaluated the productivity of agricultural water use by comparing the quantity of water delivery to the field within the output. The results indicate that 82.48, 80.40 and 66.38% of water conveyed by the system in lined main canal, lined secondary canal and unlined secondary canal, respectively reach the destined farms. The results show further more that the system of water distribution was good in terms of adequacy and poor in terms of efficiency and fair to both dependability and equity. The physical and economical water productivity was 0.97 kgm-3 and 0.45$m3 at head, 1.36 kgm-3 and 0.63$m3 at the middle and 1.41 kgm-3 and 0.65 at the tail. The results show further that the water productivity performance was found to be 0.72, 1.16, and 1.31 at the head, middle and tail, respectively. The findings from survey have shown that the majority of farmer lack of crop water requirement. The study suggests adding more efforts for improving efficiency, temporal uniformity and equity in water allocation.
