Chak Bandi (चकबंदी) or Killa Bandi (किल्लाबंदी), in terms of land and revenue, is the process of land consolidation, and Revenue Settlement. "Chak bandi" and "Settlement" is done by the "Settlement Officer" with the help of patwaris, lambardars and earlier zaildar (now abolished). Chakbandi, in terms of irrigation, means that each chak is irrigated by a branch water-course, fed by a sluice channel in the bank of the main canal where the amount of water given to each chak (farm) owner is in proportion to the area of its chak. Block of contiguous land irrigated by the specific Rajwaha, also called irrigation circle, were given a unique chak number each. The Chak (चक) is also referred to as the Chakla (चकला), which is different from the Chakla-belan for making roti or the Chakla (brothel).
