The objective of this study is to assess the performance of irrigation water management of the Great Chao Phraya Irrigation Scheme consisting of 25 operation and maintenance irrigation projects (OMPs) in the Chao Phraya River Basin, central Thailand. Benchmarking is used to evaluate irrigation performance amongst the schemes. The eight performance indicators are crop yield ratio, output per unit area, operation and maintenance (O&M) cost, total financial viability, efficiency of infrastructure, sufficiency of irrigation staff, irrigation ratio and cropped area ratio. The results provide a feasible mechanism for performance improvement in the irrigation and drainage sector, but need strong support from key stakeholders. Though there are some uncertainties concerning the quality of secondary data, experience and insight gained from this study could provide valuable information for other schemes and will be a good starting point for benchmarking the performance of irrigation in Thailand.
