West Bengal's Farakka Barrage to get new navigational lock
The Inland Waterways Authority of India (IWAI), in end November, awarded the work for the construction of the navigational lock, to Larsen and Toubro Ltd (L&T), at a cost of Rs 359 crore, under Jal Marg Vikas Project (JMVP), which is being implemented in National Waterway-1 (River Ganga).
A navigational lock is a device used for raising and lowering ships/vessels between stretches of water of different levels on river and canal waterways.
The existing lock gate at Farakka which has been operational since 1978, is old and inefficient.
Since the modernisation of the existing lock will entail closing down the lock gate for to 8-10 months, it has been decided to first build a new navigational lock and subsequently the modernisation of the existing lock would be undertaken.
With the existing lock it takes about two hours or more for a vessel to pass upstream or downstream of Farakka.
With the new lock it will take only 38 minutes for a vessel to pass through, the ministry said.
If movement of a vessel is followed by movement of another vessel in the reverse direction, the operating time will be 23 minutes only.
The new lock is proposed with modern state of the art features like electro-hydraulic operations of Mitre Gates and Radial Gates on filling culverts and remote control operations of all the gates from a central control room, according to the ministry.
The Farakka navigational lock is the third major work on National Waterway-1 to be awarded in record time.
The contract for construction of Multi-Modal Terminal (MMT) at Varanasi and Sahibganj were awarded in May and October 2016, respectively.
The Jal Marg Vikas Project is being implemented with technical and financial assistance of the World Bank at an estimated cost of Rs. 5,369 crore for plying of vessels with capacity of 1500-2,000 tons.
Phase-I of the project covers the Haldia-Varanasi stretch which includes development of fairway, Multi-Modal Terminals, strengthening of river navigation system, conservancy works, modern River Information System (RIS), Digital Global Positioning System (DGPS), night navigation facilities, modern methods of channel marking etc.
