Laying of underground pipelines across the Salem – Bangalore National Highway 7 for the Mettur – Salem Dedicated Water Supply Scheme using trenchless technology began recently.

The technology involves digging the roads horizontally at a five metre depth and laying 1,100 mm diameter pipelines instead of digging the top of the roads and disrupting traffic.

The work is expected to be completed in a month’s time.

The Rs. 320 crore scheme is implemented in two packages with Package VI implemented at a cost of Rs. 42.43 crore. The package includes laying of pipelines along the highway for a total of 11.80 km from Omalur – Tharamangalam Main Road till Mamangam which is the city’s entry point.

The pipeline will cross the highway at three places, near Dalmia Board, Reddipatti Junction and near a private hospital. The trenchless technology is being adopted for the first time in the city. There will be no need for traffic diversion and the work will not cause environmental pollution either. The National Highways Authority of India (NHAI) has recently accorded permission for carrying out the work.
