Evaluation of irrigation and drainage systems can help managers find problems and deliver water in the system more efficiently. Adequacy, efficiency, equity and dependability are important indicators for evaluation of management in irrigation and drainage systems. Evaluation of overall performance based on the above‐mentioned four indicators can be useful for more accurate judgement about system performance. In this paper, a new simple overall water delivery performance indicator (OPI) and a general form (OWDPI) are defined based on the combination of the four previously mentioned indicators, adequacy, efficiency, equity and dependability. Three performance classes were also defined to represent standard values. The overall performance indicator was used for evaluation of the Doroodzan Irrigation Network (DIN) in south‐western Iran. Results showed that although adequacy in 2001 and efficiency in 2015 were good for DIN, the overall delivery performance indicator was poor and equal to 0.70 and 0.72 in the 2 years of study. The developed overall performance indicator may be a suitable tool for better evaluation and comparison of DIN and other similar irrigation and drainage systems around the world. © 2019 John Wiley & Sons, Ltd.
