This paper intends to investigate the service life time and to formulate a model of performance index degradation of surface irrigation system. The study conducted in all of technical surface irrigation area in Indonesia which has the assessment of irrigation performance and the real value of operation and maintenance demand during six months. The secondary data and site visit to location (primary data) are used for analysis in this study. The methodology consists of analysis on the physical aspects index that are physical infrastructure index and supporting aspect index. The supporting aspect index consists of 5 parameters that are crop productivity, supporting means, management organization, and institutional condition. Result shows that performance index degradation of surface irrigation system is as the addition between physical aspect and supporting aspect. The dominant parameter in the supporting aspect is crop productivity. © 2018 IAEME Publication.
