The ‘Khadin’ system of rainwater harvesting in Rajasthan is a very long (100 m - 300 m long) earthen embankment called ‘Bund’ built across the lower edge of the sloping farmland. The rainwater from the catchment area flows down the slopes and stopped by the ‘Bund’ to form a reservoir. The rainwater which collects in the reservoir formed by the ‘Bund’, and in the well, seeps slowly into the land (or ground). This water - saturated land is subsequently used for growing crops.
