Trenchless technology to be used for water supply project

The Tiruchi Corporation would adopt trenchless technology to lay pumping mains of the on-going Drinking Water Supply Augmentation Scheme in critical junctions and crossings at 11 places in the city.

The drinking water scheme is being executed at an estimated cost of Rs.221.42 crore with financial assistance from the Japan International Cooperation Agency.

In an attempt to expedite the laying of the pumping mains the Corporation has decided to adopt the trenchless technologies wherever the pipes have to be laid across the highways or railway crossings.

The Corporation would spend about Rs.2.38 crore for the purpose.

Explaining the rationale behind the move, a Corporation engineer said that apart from saving time the technology also averted the need for cutting roads, for which clearances have to be taken from the concerned agencies such as the National Highways and the National Highways Authority of India.

Pumping mains are to be laid for a total distance of about 89 km under the project, which seeks to ensure equitable supply of drinking water to all parts of the city. Work was fast underway on laying the pumping mains from the Collector wells located on the Coleroon River bed in the city.

Pipelines would be laid using the trenchless technology at the railway crossings at Manjathidal, Kudamuritti and at a couple of other places on the Tiruchi-Chennai and Tiruchi-Karaikudi railway lines.

This apart, pipelines would also laid across at different points across the Tiruchi-Padalur section of the Tiruchi-Chennai National Highway, the Tiruchi-Thanjavur highway, Tiruchi-Pudukottai Highway and the Tiruchi-Madurai Highway.
