[Assam] geo-tube dyke

[Manoj Das]

Dear C'da

The job was reportedly given to a Malaysian Company at a cost of Rs. 140
crores (if I remember correctly). First time our good old thikadars and
nuniyas are out. Was wondering what this technology is like. Can you explain
a bit more.? Pl be reminded that the area witnesses huge siltation.

Regards
Manoj
