New Pipelines to Ensure Quality Water

People complaining about contamination of drinking water in some parts of city can heave a sigh of relief as Chennai Metro Water is on the verge of completing the first phase of relaying 20 km of pipeline.

A Metro Water spokesman said that 19 km of pipeline has been completed to ensure quality drinking water in people living in Triplicane, Anna Nagar and North Chennai areas of Tondiarpet, Perambur and Kolathur.

The Rs 9.45 crore scheme was started after Chennai Metro Water identified specific pockets where contamination occurs due to aged and corroded pipes. He said the second phase of work on replacement of choked water main lines will be taken up after identifying pockets based on the complaints.

Meanwhile, the replacement of old sewer main lines for a total of 117km under Chennai Mega City Development Mission 2011-12 has been taken up and laying of new pipeline for a length of 100km have been completed at a cost of Rs 52 crore.

  1. Replacement of corroded pipes with a new pipeline is a welcome step to supply good quality water to Public. Corrosion of pipelines is leading the way for contamination in drinking water systems. We loose significant proposition of water through corrosion induced leakages. When pipeline replacement is done there should be a structured program in place to monitor corrosive nature of water supplied to the public and ensure integrity of the entire water distribution network. Corrosion awareness is very limited in our country. Corrosion management professionals have to be necessarily inducted in various phases of project starting from design through to operation and maintenance of distribution network. Costly replacement with the new pipeline is the resultant effect when scope for finding appropriate corrosion control is limited. Ultimately public funds are wasted through improper selection of materials and inadequate corrosion control activities.
