- Construct no wider and taller than 50 cm x 30 cm bunds, around the field.
- 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).
- 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.
