The major soil types in Lakshadweep are coral sand derived from coral limestone. The islands of Lakshadweep have a soil layer overlying coral limestone. The island soil includes coral sands and lagoonal sands. These soils are highly permeable and allow rainfall to readily infiltrate, with the result that surface run-off does not occur except in local areas of compacted soils. (Source: CGWB Report, 2009).

The average rainfall of Lakshadweep is 1640 mm. Though the islands receive high rainfall, storage of freshwater is difficult due to high permeability nature of coral sand. Net annual ground water availability: 349.86 ha.m Annual Ground Water Draft: 258.79 ha.m (Source: CGWB Report, 2011)
