Tamil Nadu Minister for cooperatives Sellur K Raju, who inaugurated the unconventional method to conserve water in drought hit Tamil Nadu, saw the attempt go awry as the sheets flew in different directions due to the wind. 

The minister later held discussions with PWD experts on ways to overcome the problem of wind and water flow, which led to the sheets drifting in various directions, officials said. 

Water from the Vaigai dam flows through six water starved districts of south Tamil Nadu. 

The minister said that the “thermocol covering technology” had come from a “source”, but refused to specify what it was.  

Journalists, who were part of the team taken to the spot to demonstrate the ‘technology’, found there were not enough sheets to cover the water. 

Raju claimed such methods are used abroad to reduce evaporation and that experts would also be consulted for these initiatives. 

He said the state government had allocated Rs 10 lakh to try out different technolgoies to prevent water evaporation. 

Madurai Collector K Veera Raghava Rao said different methods would be adopted or experimented to save water which is in 10-12 hectares of water-spread area in the Vaigai dam. 

He said 1.2 million cubic feet of water is lost due to evaporation every day. 

The official said thermocol was used as the material was non-polluting (Fun Fact: it isn’t).
