This paper explores the variation of equity of water distribution in Pehur Main Canal (PMC) irrigation system in the context of time and space. This canal operates under warabandi scheduling of water supply with the aim of achieving social justice. The data for this study was collected from the Mogawar, official outlet-wise register. The equity is measured on a scale of 0-1, 1 for complete equity and 0 for complete inequity. The data analysis shows most of values closer to 0. Temporally equity in Rabi season is better than the summer (early Kharif) season. The spatial distribution of equity during both Rabi and summer seasons is random in majority of secondary canals. Most of secondary canals have better equity in their middle and tail sections then their respective head and mid-sections. This situation points to lack of operational maintenance of irrigation system.
