How to construct bunds

1. Construct no wider and taller than 50 cm x 30 cm bunds, around the field.
2. Make sure that bunds are well compacted and properly sealed, with no cracks, holes, etc. This will minimize water losses through seepage (particularly in sloping lands).
3. Adjust the spillway height to 3−5 cm for storing the same depth of water. Maintain this height to ensure sufficient water storage capacity especially during rainy or wet season.

For rat control, construct 30 cm x 30 cm bunds.
