Navigational Lock - Farakka

Navigational Lock - Farakka

 

The Site is located at Farakka in Murshidabad district of West Bengal, on the Feeder Canal of Farakka Barrage.

A barrage was constructed across river Ganga at Farakka to divert the water from Ganga to Bhagirathi through a feeder canal. There is a significant difference in water level of the upstream pond of the Barrage and feeder canal, depending upon the flow in river Ganga and the feeder canal. To negotiate this difference, a navigation lock is required. The navigable route through the main Ganga River upstream to the River Bhagirathi downstream is facilitated by a navigation lock at Farakka. The Feeder Canal of Farakka Barrage and the navigation lock becomes the link between the main Ganga and Bhagirathi. The existing lock has become dysfunctional and a new lock is constructed in parallel to the existing lock.

 

The navigational lock is part of The Jal Marg Vikas (National Waterway-1) project, financed by the Worldbank. Larsen and Toubro Engineering and Construction Company (LNTECC) have signed an engineering, procurement and construction (EPC) agreement with Inland Waterways Authority of India (IWAI) for the New Navigational Lock.

SBE International was appointed as the designer for the hydro-mechanical components (including lock gates, lock appurtenances, Electromechanical and control systems and hydro-electrical drive systems) of the lock.
