All the inhabited islands are problem villages as far as drinking water supply is concerned. A central team consisting of Advisor(TM), Department of Rural Development along with experts from Central Ground Water Board, CSMCRI Bavanager, NEERI Nagpur, CESS Thiruvananthapuram after their visit to Lakshadweep came to the clonclusion that no single system or approach to provide water supply to Lakshadweep islands would be sufficient due to typical geological and
Hydrogeological nature of these islands. They suggested tapping of ground water to the extend of its sustainable yield and supplement it with additional activities such as installation of Desalination Plants, rain water harvesting etc. Accordingly the Water Supply scheme was modified to have a combination of ground water, Reverse Osmosis Desalination Plants and rain water harvesting. In all islands water supply system is in existence partially in quantity ranging from 15-20 litres to 30-35 litres only. Now more attention has given to construction of individual rain water harvesting stuctures, since the system is more adoptable to these area.
