Harvesting rain in Andaman in Kerala Style
Port Blair | Thursday, Oct 15 2009 IST
KJ Antoji, a renowned rain water harvester of Kerala and a NRDC (Natural Resources Defence Council) award winner, today claimed that water crisis of the islands could be solved to a great extent if his new rain water harvesting technology was adopted.
''In this technique, rain water is collected in a 1000 litres tank and the pressure of the water tank helps the water injection device to inject water into the ground which enables the recharge of the earth's water table and accordingly fresh water is pumped through a motor for use,'' Mr Antoji told mediapersons at Port Blair while addressing a press conference.
He said this technology is being used in Kerala, since 1998, especially in his village Chellanam in Kochi, a saline affected coastal village, whereby using this rain water injecting system the salinity of the water has come down by 80 per cent.
Mr Antoji, in this regard, has already completed a pilot project at a resort in Havelock Island, which was badly hit by water shortage and was forced to close down for three months. But with Antoji's method the resort is now getting nearly 1500 litres of clean water daily.
Mr Antoji said since the complete storage in this project is underground, there is no mosquito menace or formation of larva or worms, as this system avoids stagnation of water above the ground level.
''The greatest advantage of this technology is that it needs one time investment of setting up the unit and there are no recurring charges or maintaining cost,'' he added.
So far 200 rain water harvest units in various districts' and in coastal villages of Kerala have been installed with more than 90 per cent success rate and in the last 10 years approximately 45 crore liters of water has been injected back into the earth helping to recharge the earths water table.
