Tunnelling Work Completed for Barauni-Guwahati Gas Pipeline

The micro-tunnelling work for the Barauni-Guwahati gas pipeline project has concluded with the completion of a major line under the confluence of three Kanamakra, Aie and Manas rivers in Chirang district of Assam.

The breakthrough of the micro-tunnel boring machine was achieved by Ace Energy Infrastructure on 2 July, 2023, with the construction of a tunnel of diameter 1,600 mm across 1,200 mtrs. at a depth of 11-12 mtrs. under the river bed.

Further, a 24-inch carbon steel pipeline will be installed in the next few weeks to transport natural gas in this tunnel. On completion, it will serve as a final link to complete a 1,600-km network of gas pipelines from Barauni to Guwahati, and further from Guwahati to Numaligarh.

The Bihar portion of the gas pipeline was completed in April, 2023, by connecting six districts of the state to the national gas grid. The gas pipeline is a part of the extension of Urja Ganga Project which will provide natural gas connectivity from Guwahati to Numaligarh and North-eastern cities and towns.
